Use the terms primary key field, foreign key field, one-to-many relationship, parent table and child table to describe the following WHERE clause: WHERE Clients.ClientID = Projects.ClientID

Answers

Answer 1

Hi! I'd be happy to help you with your question. The WHERE clause you provided, "WHERE Clients.ClientID = Projects.ClientID", can be described using the terms primary key field, foreign key field, one-to-many relationship, parent table, and child table as follows:

In this scenario, the Clients table is the parent table, and the Projects table is the child table. The primary key field in the parent table (Clients) is ClientID, which uniquely identifies each client. The foreign key field in the child table (Projects) is also ClientID, which establishes a link between the two tables by referencing the primary key in the parent table.

The relationship between the Clients and Projects tables is a one-to-many relationship, as one client (from the Clients table) can be associated with multiple projects (in the Projects table), but each project is linked to only one client.

The WHERE clause "WHERE Clients.ClientID = Projects.ClientID" is used to retrieve records where there is a match between the primary key field in the parent table (Clients.ClientID) and the foreign key field in the child table (Projects.ClientID), effectively displaying the combined data for clients and their corresponding projects.

Two chambers with the same fluid at their base are
separated by a 30-cm-diameter piston whose weight is 25
N. Calculate the gage pressures in chambers A and B

Answers

Answer:

Pgage at A = 101.30354 kPa

Pgage at B = 101.29646 kPa.

Explanation:

To calculate the gauge pressures in chambers A and B, we need to use the formula:

Pressure = Force / Area

where force is the net force acting on the piston and area is the cross-sectional area of the piston.

First, let's calculate the net force acting on the piston. We know that the weight of the piston is 25 N, which is acting downwards. We also know that the piston is in equilibrium, so the net force acting on it is zero. Therefore, there must be an upward force acting on the piston that is equal in magnitude to the weight of the piston. This upward force is the pressure difference between the two chambers pushing up on the piston.

The area of the piston is given by:

Area = pi * (diameter/2)^2

= pi * (30 cm / 2)^2

= 706.9 cm^2

Now we can calculate the pressure difference between the two chambers:

Pressure difference = Force / Area

= 25 N / 706.9 cm^2

= 0.0354 N/cm^2

Since the fluid in both chambers is at the same level, the pressure in chamber A is equal to the atmospheric pressure plus the pressure difference, and the pressure in chamber B is equal to the atmospheric pressure minus the pressure difference. Assuming the atmospheric pressure is 101.3 kPa, we can calculate the gauge pressures in chambers A and B as follows:

Pressure in A = Atmospheric pressure + Pressure difference

= 101.3 kPa + 0.0354 N/cm^2

= 101.3 kPa + 0.00354 kPa

= 101.30354 kPa

Pressure in B = Atmospheric pressure - Pressure difference

= 101.3 kPa - 0.0354 N/cm^2

= 101.3 kPa - 0.00354 kPa

= 101.29646 kPa

Therefore, the gauge pressure in chamber A is 101.30354 kPa and the gauge pressure in chamber B is 101.29646 kPa.

Answers

calculating the dry unit weight, first, find the dry mass of the soil using the wet mass and water content.
So, the dry unit weight is most nearly option c) 18.1 kN/m³.

To calculate the dry unit weight of the soil, we first need to calculate the mass of dry soil. We know that the wet mass of soil is 2 kg and the water content is 15%, so the mass of dry soil can be calculated as follows:

Mass of dry soil = Wet mass of soil / (1 + Water content)
Mass of dry soil = 2 kg / (1 + 0.15)
Mass of dry soil = 1.739 kg

Next, we can calculate the volume of the soil using the mold volume:

Volume of soil = Mold volume x Bulk density
Bulk density = Wet mass of soil / Mold volume

Bulk density = 2 kg / 942 x 10^-6 m³
Bulk density = 2121.99 kg/m³

Volume of soil = 942 x 10⁻⁶ m³x 2121.99 kg/m³
Volume of soil = 2.002 m³

Finally, we can calculate the dry unit weight:

Dry unit weight = Mass of dry soil / Volume of soil
Dry unit weight = 1.739 kg / 2.002 m³
Dry unit weight = 867.91 kg/m³

Converting to kN/m²:

Dry unit weight = 867.91 kg/m³x 9.81 m/s² / 1000
Dry unit weight = 8.51 kN/m²
Therefore, the answer is most nearly (c) 18.1 kN/m².

Give your answer in units of N/mm. Do not include the units Blackboard will not understand.

Answers

The spring constant of this helical compression spring made of music wire is 71.43 N/mm.

A helical compression spring is a mechanical spring made from wire coiled into a helical shape, with the ends of the spring designed to compress under a load. When a force is applied to the ends of the spring, the coils are compressed, and the spring stores energy. When the force is removed, the spring expands to its original shape and releases the stored energy. To calculate the spring constant (k) for a helical compression spring, we can use the following formula:
[tex]k = (G * d^4) / (8 * D * N)[/tex]
where:
G = modulus of rigidity (80 GPa or 80,000 N/mm²)
d = wire diameter (2.2 mm)
D = mean coil diameter (spring index = D/d, so D = 11 * 2.2 = 24.2 mm)
N = total active coils (13)
Plugging in the values, we get:
[tex]k = (80,000 * 2.2^4) / (8 * 24.2 * 13) = 71.43 N/mm[/tex]
So, the spring constant of this helical compression spring made of music wire is 71.43 N/mm.

A solid metal sphere with radius 0.430 m carries a net charge of 0.280 nC.
A. Find the magnitude of the electric field at a point 0.104 m outside the surface of the sphere.
B. Find the magnitude of the electric field at a point inside the sphere, 0.104 m below the surface.

Answers

A. The magnitude of the electric field at a point 0.104 m outside the surface of the sphere is 1.36 x 10⁶ N/C.

B. The magnitude of the electric field at a point inside the sphere, 0.104 m below the surface, is 3.02 x 10⁶ N/C.

A. To find the magnitude of the electric field at a point 0.104 m outside the surface of the sphere, we can use the equation for electric field of a point charge:
E = kq/r²
where E is the electric field, k is Coulomb's constant (9 x 10⁹ N*m²/C²), q is the charge, and r is the distance from the charge.
Since the sphere has a net charge, we can treat it as a point charge located at the center of the sphere. The distance from the center of the sphere to the point outside the surface is:
r = 0.430 m + 0.104 m = 0.534 m
Plugging in the values, we get:
E = (9 x 10⁹ N*m²/C²) * (0.280 x 10⁻⁹ C) / (0.534 m)²
E = 1.36 x 10⁶ N/C
Therefore, the magnitude of the electric field at a point 0.104 m outside the surface of the sphere is 1.36 x 10^6 N/C.

B. To find the magnitude of the electric field at a point inside the sphere, we need to consider that the charge distribution inside the sphere is not uniform. However, since the point is very close to the surface, we can approximate the electric field as if the entire charge is located at the center of the sphere.
The distance from the center of the sphere to the point inside the sphere, 0.104 m below the surface, is:
r = 0.430 m - 0.104 m = 0.326 m
Using the same equation as before, we get:
E = (9 x 10⁹ N*m²/C²) * (0.280 x 10⁻⁹ C) / (0.326 m)²
E = 3.02 x 10⁶ N/C
Therefore, the magnitude of the electric field at a point inside the sphere, 0.104 m below the surface, is 3.02 x 10⁶ N/C.

if σ = 0.4 and w = 16,000 kg, determine the minimum drag and the velocity at which it occurs. (round the final answers to two decimal places.)

Answers

To determine the minimum drag and the velocity at which it occurs, we need to use the following formula: D = (1/2)ρV^2CDA where: - D is the drag force - ρ is the density of the fluid- V is the velocity of the object
- CDA is the coefficient of drag times the frontal area of the object To solve for the minimum drag, we need to find the velocity at which the drag force is at a minimum.

This can be done by differentiating the above formula with respect to  V and setting it equal to zero: dD/dV = ρVCDA = 0 Solving for V, we get: V = 0 This means that the minimum drag occurs at zero velocity, which makes sense since there is no drag force when the object is at rest. To solve for the minimum drag, we can substitute V = 0 into the original formula: D = (1/2)ρ(0)^2CDA = 0 So the minimum drag is zero. Therefore, we cannot determine the velocity at which the minimum drag occurs because it occurs at zero velocity. Note that the final answer for the minimum drag is already rounded to two decimal places, which is zero.

a parallel polarized plane wave is incident from air onto a dielectric medium with εr = 4 at the brewster angle.

Answers

The angle of incidence at which the parallel polarized plane wave is incident from air onto the dielectric medium with εr = 4 is known as the Brewster angle.

The Brewster angle, also known as the polarization angle, is the angle of incidence at which a polarized light wave is perfectly reflected from a surface, with the reflected light having only perpendicular polarization. This angle is dependent on the refractive indices of the materials involved in the reflection process. When the incident angle is equal to the Brewster angle, the reflected and transmitted waves are at right angles to each other, which means the reflected light is completely polarized in the plane of incidence. This phenomenon is useful in various optical applications, such as polarizing filters, where the polarization of light can be controlled by adjusting the angle of incidence. In addition, the Brewster angle also plays a crucial role in the reflection of electromagnetic waves from dielectric surfaces, such as radio waves from the Earth's surface.

Answers

A multiplier value of zero for any of the Revised NIOSH Lifting Equation means that the factor being multiplied by has no impact on the overall equation. This can occur if, for example, the lifting task does not involve twisting or awkward postures.

If a job has an L1 greater than 1, it means that the task may not be performed safely without modifications or improvements. An L1 value greater than 1 indicates that the recommended weight limit for the task is lower than the weight being lifted, which increases the risk of injury.
For the lifting task and RWL given, the resulting RWL of 16.77 indicates that the task is within the recommended weight limit. However, there may still be room for improvement in terms of reducing other factors in the lifting equation, such as the lifting distance or frequency. Modifying the task or using assistive equipment may also help to further reduce the risk of injury. Hi there! A multiplier value of zero in the Revised NIOSH Lifting Equation means that one or more factors in the lifting task are at their least favorable condition, making the task extremely unsafe to perform. The equation is used to calculate the Recommended Weight Limit (RWL) for lifting tasks, considering various factors that impact lifting safety.The Lifting Index (LI) is the ratio of the Actual Load (AL) to the RWL. If the LI is greater than 1, it indicates that the lifting task exceeds the recommended safe limits, and there is an increased risk of injury. However, even with an LI greater than 1, a task can still be performed safely if proper precautions, techniques, and equipment are used to minimize the risk.In the given lifting task, the RWL is 16.77. To improve the task's safety, you can:
Reduce the weight of the load
Adjust the lifting posture to minimize reach or horizontal distance

sketch a typical longitudinal stream profile, label areas of erosion, deposition, and what clast sizes typically would be found where.

Answers

The longitudinal stream profile provides valuable information about the geomorphology of a stream, including areas of erosion and deposition, as well as the size and type of sediment being transported.

A longitudinal stream profile shows the changes in elevation along the length of a river or stream. Typically, the profile starts at the source of the stream and follows its path downstream to the mouth.

Areas of erosion are typically found near the headwaters of the stream, where the gradient is steeper, and the water is moving faster, allowing it to pick up and transport larger clasts. These areas are typically characterized by steep, V-shaped valleys and rapids or waterfalls.

Areas of deposition are typically found near the mouth of the stream, where the gradient is flatter, and the water is moving slower, allowing it to deposit the sediment it has been carrying. These areas are typically characterized by wide, flat floodplains and meandering channels.

In terms of clast sizes, larger clasts (such as boulders and cobbles) are typically found near the headwaters, while smaller clasts (such as sand and silt) are found further downstream where the water is moving slower and has less energy to transport larger particles.

Answers

Hi! I'm happy to help you with the circuit analysis question involving radian frequency (ω) and capacitor behavior.

(a) To determine the phasor gain va/vi as ω → 0, consider the behavior of the capacitor at DC (ω = 0). At DC, a capacitor acts as an open circuit. Therefore, no current will flow through the capacitor, and the output voltage va will be equal to the input voltage vi. Thus, the phasor gain va/vi will be 1.

(b) To find the gain va/vi as ω → ∞, consider the behavior of the capacitor at very high radian frequencies. At high frequencies, a capacitor acts as a short circuit. In this case, the output voltage va will be 0, as the voltage across the capacitor is shorted. Therefore, the gain va/vi will be 0.

(c) Based on the answers from parts (a) and (b), we can infer that the filter implemented by this circuit is a lowpass filter. This is because the gain is 1 at low frequencies (DC), and the gain approaches 0 at high frequencies.

The ambient temperature for the trip.is 45°c. The Red Box is compowered. The triptakes 3 hours, Will our hapless driver make it before the Red Box damages the DVDS? (Initial conditions)

Answers

Based on the initial conditions, the Red Box is at a temperature of 13°C when the driver leaves the warehouse. However, the ambient temperature for the trip is 45°C which is significantly higher than the internal temperature of the Red Box. This means that the temperature inside the Red Box will rise during the trip, potentially damaging the DVDS inside.

Since the Red Box is powered, it's possible that it has a cooling system to regulate its internal temperature. However, without knowing more details about the specific Red Box being used, it's difficult to determine whether the cooling system is sufficient to prevent damage to the DVDS.
Assuming that the cooling system is not sufficient, it's likely that the temperature inside the Red Box will rise above the recommended temperature range for DVDS, which is typically between 5°C and 35°C. If this happens, it's possible that the DVDS inside will become damaged.
Since the trip takes 3 hours, it's important for the driver to take steps to minimize the temperature rise inside the Red Box. This might include keeping the Red Box in a shaded area or turning up the air conditioning in the delivery vehicle to keep the ambient temperature as low as possible.
Overall, it's difficult to say whether the hapless driver will make it before the Red Box damages the DVDS without knowing more details about the cooling system and the specific DVDS being transported. However, it's important for the driver to take steps to minimize the temperature rise inside the Red Box and protect the DVDS from damage.

Answers

The code provided is for two sorting algorithms - selection sort and insertion sort - that operate on a ListADT. The selection sort algorithm works by finding the largest element in the unsorted part of the list and swapping it with the last element in the unsorted part. The insertion sort algorithm works by inserting each element in the unsorted part into the sorted part of the list, one at a time.

Both algorithms have two versions - one that takes a Comparator object as input and one that doesn't. The Comparator object is used to compare elements in the list and determine their order.
The try-catch blocks in both algorithms catch any Exceptions that may be thrown during the sorting process and print their stack traces using the ".printStackTrace();" method.
Overall, these algorithms provide a way to sort a ListADT using either selection sort or insertion sort, with or without a Comparator object.
It looks like you have provided code for sorting algorithms using ListADT and Comparator. Here's a brief explanation of the code:
1. The code implements two sorting algorithms: selection sort and insertion sort.
2. There are two versions of each algorithm: one that takes a Comparator as an argument, and another that uses the compareTo method of the elements in the ListADT.
3. The try-catch blocks in each method, containing "Exception ex" and "ex.printStackTrace();", handle any exceptions that might occur during the sorting process. If an exception is thrown, the stack trace will be printed to help identify the cause of the error.
I hope this helps! If you have any specific questions about the code, please feel free to ask.

If you have a Products table and you want to increase the Price by 15% for all products that have a price greater than $15.00, write the update statement. (ProductID, Price)For the same Products table write a query that will count all the products with a Price greater than $15, and the count is greater than 3.

Answers

To update the price of all products with a price greater than $15 by 15%, you can use the following SQL statement:

UPDATE Products
SET Price = Price * 1.15
WHERE Price > 15.00;

This will update the Price column of the Products table for all rows where the Price is greater than $15.00, increasing the price by 15%.

To count all the products with a Price greater than $15 and a count greater than 3, you can use the following SQL query:

SELECT COUNT(*)
FROM Products
WHERE Price > 15.00
GROUP BY Price
HAVING COUNT(*) > 3;

This query will count all the products with a Price greater than $15, group them by their Price, and then filter out any groups with a count less than or equal to 3. The result will be a single count of all products that meet these criteria.

what special property of the exclusive or gate that allows us to build an adder-subtractor circuit using full adders and exclusive or gates?

Answers

The special property of the exclusive or (XOR) gate that allows us to build an adder-subtractor circuit using full adders and exclusive or gates is its ability to perform both addition and subtraction operations through a simple modification of the input values.

In an adder-subtractor circuit, full adders are used for binary addition, while XOR gates are used to control the operation (addition or subtraction) by selectively inverting the bits of one of the input numbers. When the control signal is 0, the XOR gates pass the input bits unchanged, and the full adders perform binary addition. When the control signal is 1, the XOR gates invert the input bits, and the full adders perform binary subtraction using 2's complement arithmetic.

This unique property of the XOR gate makes it a versatile component for building adder-subtractor circuits.

an angle is measured by 7 equally competent surveying crews. three crews measured 42.11 degrees, and four crews measured 42.07. what is the probable value of the angle? O (A) (42.11+ 42.07)/2 (B) (4) (42.11) + (3) (42.07)/7 O (C) (3) (42.11) + (4) (42.07)/7 O (D) (3) (42.11) (4) (42.07)/7

Answers

The probable value of the angle is closest to option (C), which is (3 x 42.11 + 4 x 42.07) / 7.

How to calculate the value

We can find the probable value of the angle by taking the weighted average of the measurements taken by each crew. Since there are 7 crews in total, and 3 crews measured 42.11 degrees while 4 crews measured 42.07 degrees, we can write:

Probable value of angle = [(3 x 42.11) + (4 x 42.07)] / 7

Probable value of angle = (126.33 + 168.28) / 7

Probable value of angle = 294.61 / 7

Probable value of angle ≈ 42.09 degrees

Therefore, the probable value of the angle is closest to option (C), which is (3 x 42.11 + 4 x 42.07) / 7.

an op-amp with an open-loop gain of 3x106 and vcc = 12 v has an inverting-input voltage of 6.3 microvolts and a non-inverting input voltage of 4.8 microvolts. what is its output voltage?

Answers

The output voltage of an op-amp with an open-loop gain of 3x10^6, Vcc = 12V, an inverting-input voltage of 6.3 microvolts, and a non-inverting input voltage of 4.8 microvolts is 4.5 volts.

To calculate the output voltage, follow these steps:

1. Determine the voltage difference between the inverting and non-inverting input voltages:

6.3 microvolts - 4.8 microvolts = 1.5 microvolts.

2. Multiply the voltage difference by the open-loop gain:

1.5 microvolts * 3x10^6 = 4.5 volts.

3. Check if the calculated output voltage exceeds the power supply voltage (Vcc). Since the calculated output voltage (4.5V) is less than Vcc (12V), the op-amp is operating within its linear range.

4. Therefore, the output voltage of the op-amp is 4.5 volts.

#SPJ11

To calculate the output voltage of the op-amp, we need to use the formula for the voltage gain of an inverting amplifier:

Vout = -(Rf/Rin) * Vin

where Rf is the feedback resistor, Rin is the input resistor, and Vin is the input voltage. Since this is an ideal op-amp, the input impedance is infinite, which means that Rin can be assumed to be zero.

Given that the open-loop gain of the op-amp is 3x10^6, we can assume that the output voltage will be very close to the maximum possible value of 12 V. This means that the voltage across the feedback resistor (Rf) will be 12 V - Vout.

Now we can use the given input voltages and the voltage gain formula to solve for Vout (output voltage):

Vout = -(Rf/Rin) * Vin
Vout = -(Rf/0) * (Vnon-inverting - Vinverting)
Vout = -Rf * (4.8 uV - 6.3 uV)
Vout = 1.5 uV * Rf

Since we don't know the value of Rf, we can't calculate the exact value of Vout. However, we know that it will be very close to the maximum possible value of 12 V, due to the high open-loop gain of the op-amp.

why bubbling-up in min heap is needed? explain with an example.

Answers

Bubbling-up in a min-heap is needed in order to maintain the heap property, which states that the parent node must always be smaller than its children.

When a new element is added to the heap, it is placed at the bottommost level and compared to its parent node. If the new element is smaller than its parent, they swap positions. This process is repeated until the heap property is satisfied.

For example, let's say we have a min heap with the following elements: 2, 5, 7, 10, 12, 15. If we want to add element 4 to the heap, it would be placed at the bottommost level as the rightmost node. The heap property is then checked by comparing 4 to its parent node, which is 5. Since 4 is smaller than 5, they swap positions. The heap property is still not satisfied, so the process is repeated with 4 and its new parent node, 2. 4 is smaller than 2, so they swap positions. Now the heap property is satisfied and the resulting heap is 2, 4, 7, 10, 12, 15. Such is an example of bubbling up.

In this exercise, we will look at the different ways capacity affects overall performance. In general, cache access time is proportional to capacity. Assume that main memory accesses take 70 ns and that memory accesses are 36% of all instructions. The following table shows data for L1 caches attached to each of two processors, PI and P2.

Answers

In this exercise, we can see that capacity has a direct impact on cache access time and overall performance. The table provided shows that PI and P2 have different L1 cache capacities, with PI having a larger capacity than P2.

This means that PI may have a faster cache access time, resulting in better overall performance compared to P2. However, it's important to note that capacity isn't the only factor that affects performance, as other factors such as cache organization and hit rates also play a role. Therefore, it's important to consider all of these factors when analyzing the impact of capacity on overall performance.
Hi! In this exercise, we analyze how capacity impacts overall performance in the context of L1 caches for two processors, PI and P2. Generally, cache access time is proportional to capacity, which means that as capacity increases, access time may also increase. With main memory accesses taking 70 ns and accounting for 36% of all instructions, the difference in cache capacity between PI and P2 can significantly influence their respective overall performance. Comparing the L1 cache data for PI and P2 will help us understand the relationship between capacity and performance in these processors.

describe in detail the steps in inserting a key with value 184 in the original tree. show the node which undergoes the change, and how does it look after the change. [5 points]

Answers

The steps involve traversing the tree and creating a new node at the appropriate location, and the node that undergoes the change is the one where the new node is inserted.

What are the steps involved in inserting a key with value 184 in the original tree, and what node undergoes the change?

To insert a key with value 184 in the original tree, the following steps can be taken:

Start at the root node of the tree.
Compare the value of the key being inserted (184) with the value of the root node.
Since 184 is greater than the value of the root node, move to the right child node.
Compare the value of 184 with the value of the right child node. Since there is no right child node, create a new node with the value of 184 and insert it as the right child of the current node.
The node which undergoes the change is the right child of the root node.
After the change, the node will have a value of 184 and no children nodes.

Overall, the steps involved in inserting a key with value 184 in the original tree involve traversing the tree and creating a new node at the appropriate location. The node that undergoes the change is the one where the new node is inserted, and it will have a different value and possibly different children nodes after the insertion.

write a statement that creates and initializes a static variable named salestax to 7.59.\

Answers

A statement in C++ that creates and initializes a static variable named "salestax" to 7.59 is:

static float salestax = 7.59

How to create and initializes a static variable?

In programming, a static variable is a variable that retains its value across multiple function calls. It is initialized only once, and subsequent calls to the function will use the same value that was set during the first call.

To create and initialize a static variable named "salestax" to 7.59, we can use the following C++ statement:

static float salestax = 7.59;

Here, we are declaring a static variable of type "float" named "salestax" and initializing it to the value 7.59. The "static" keyword ensures that the variable is only initialized once, and subsequent calls to the function will use the same value.

Static variables are commonly used in programming to keep track of data that needs to persist across function calls, such as a running total or a count of the number of times a function has been called. By using static variables, we can write more efficient and concise code that avoids unnecessary memory allocation and initialization.

We will refer to the side each person prefers as their "dominant" arm, and the other, non-preferred side the "subordinate" arm.Handedness can produce differences between the right and left sides of our body. The effect of preferential use of one side should be most obvious for muscle mass, since it responds directly to exercise. Tennis players are good examples of this effect - their racket arm is often much more muscular than their other arm, as you can see in these pictures of Rafael Nadal (left) and Rod Laver (right).For most people if there is any difference in muscle sizes between their dominant and subordinate arms it is likely to be much less dramatic than what we see in tennis players. Additionally, the amount of difference between dominant and subordinate arms would probably be small compared to the large amount of variation in sizes of arms between people.Given this, if we used a sample of people and measured their dominant arms, and a separate independent sample of people to measure their subordinate arms, the amount of difference between the two groups might be obscured by the individual variation among people. If instead we used one sample of people and measured the dominant and subordinate bicep circumferences on each one, we might find a small but consistent amount of difference at the level of individuals. Focusing on the differences eliminates the variation from person to person, and consistent small differences can be detected reliably once this nuisance variation between people is removed statistically.We wouldn't necessarily expect the sizes of the bones in the arms to be as responsive to exercise as muscle mass is, so we will also look at arm lengths. People's arms may not be exactly the same length, but we wouldn't necessarily expect the dominant arm to be longer than the subordinate arm.This is 1 question broken down to 2 parts: independent variable in the reaction of stoichiometry and percentage yield Throughout history, most managers operated on a trial-and-error basis.
