a .158 Kg
b 1.58 Kg
c 15.8 Kg
d 1,580 Kg
Answer:
A is the correct answer 0.158
158 Milligrams of salt are on the table there would be 0.158 grams of salt on the table, therefore the correct answer is option A.
What is a unit of measurement?A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.
As given in the problem 158 Milligrams of salt are on the table, then we have to find out how many grams of salt is on the table,
1000 milligrams = 1 gram
1 milligram = 1 / 1000 grams
158 milligram = 158 × 1 / 1000 grams
=0.158 grams
Thus, there would be 0.158 grams of salt on the table, the correct answer is option A.

WILL AWARD BRAINLY
Answer:
sry I can't help you In that
A light bulb used in homes converts electrical energy into light energy The amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.
What is electrical energy?The ability of an atom's charged particles to initiate an activity or move an object is known as electrical energy.
The proportion of the device's useful energy transferred to the device's total energy input.
The input power of the light bulb = 52 w.
In 9.0 hours of use.
Hence,
52 x 9.0 = 468 J
The following equation calculates efficiency as a percentage and is represented as follows:
Efficiency is calculated as (Usable Energy Output/Total Energy Input) x 100%.
The lightbulb's efficiency is 5.0%.
(The light energy output/ 468) x 100% = 5%
So, the light energy output = 23.4 J
Therefore, the amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.

An object's period of oscillation can always be used to solve for which 2 points
variable? *
Velocity
Weight
Frequency
Momentum
Answer:
Frequency
Explanation:
A period is the number of revolutions in a minute.
[tex] Period = \frac {time}{number \; of \; oscillations}[/tex]
Also, frequency can be defined as number of oscillation per unit time.
Mathematically, frequency is given by the formula;
[tex] Frequency = \frac {number \; of \; oscillations}{time}[/tex]
Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.
Mathematically, period is expressed as;
[tex] Period = \frac {1}{frequency}[/tex]
This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.

A ball hits a wall. What is true about the magnitude of the force experienced by the ball compared with the force experienced by the wall?
A. The ball experiences more force than the wall.
B. The ball experiences less force than the wall.
The ball and the wall experience the same force.
D. The ball experiences half the force of the wall.
Reset
Next
Answer:
The ball and the wall experience the same force.
Explanation:
According to the third law of Newton, which states that "for every action, there is an equal and opposite reaction", this means that when an object 1 acts on object 2 with a certain force, object 2 also acts on object 1 with the same magnitude of force but in an opposite direction.
According to this question, a ball hits a wall with a certain force. This means that the wall will react on the ball with the same force magnitude, but in an opposite manner. Hence, the ball and the wall experience the same force.

Explanation:
Select all of the statements that are true about the rubber ball.
If the ball is cold, its particles tend to have a small amount of kinetic energy
The particles that make up the ball are moving even when the ball is not.
The temperature of the ball depends on the kinetic energies of the particles that make up the ball.
✔️If the ball is cold, its particles tend to have a smallamount of kinetic energy.
When a substance is hot its particles generally have a large amount of kinetic energy when a substance is cold it's particles do not move as much that means the particles tend to have less kinetic energy.✔️The particles that make up the ball are moving even when the ball is not.
Like all matter the ball is made up of particles that are constay moving even ig the ball is sitting still the particles that make up the ball are still moving.✔️The temperature of the ball depends on the kinetic energies of the particles that make up the
ball.
A substance temperature is a measure of the kinetic energies of the substance's particles so the ball's temperature depends of the particles that make up the ball.#CarryOnLearning!

Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. ... Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you add calcium chloride to water, the solution heats.
What happens to pressure when the area of the surface increases ? *
Pressure will decrease whenever the surface area increases, and when the weight of the object is reduced.

Explanation :We know that,
[tex]\large \boxed{ \mathrm{pressure = \frac{mass}{area \: \: of \: \: surface}} }[/tex]
Now, we can observe that the area of surface is inversely proportional to the pressure, Therefore pressure will change opposite to the change in surface area in contact.
So, if we increase the surface area then there would be decrease in magnitude of pressure.

How much gravitational potential energy does an object have if it is located 20 m above the point that we define as O height and has a mass of 10 kg
Answer:
Explanation:
PE = mgh where m is the mass in kg, g is the pull of gravity which is 9.8, and h is the height of the object above the point to which it could possibly fall, measured in meters. Plugging in:
PE = 10(9.8)(20) so
PE = 1960 J

A 1.6 Kg bird that is flying through the air has 220 J of kinetic energy. How fast is the bird flying?
20.5 m/s
19.4 m/s
18.2 m/s
16.6 m/s
cuh
Answer:
v = 16.58 m/s
Explanation:
Given that,
Mass of a bird, m = 1.6 kg
Kinetic energy of the bird, K = 220 J
We need to find the speed of the bird. The formula for the kinetic energy is given by :
[tex]E=\dfrac{1}{2}mv^2[/tex]
Where
v is the speed of the bird
So,
[tex]v=\sqrt{\dfrac{2E}{m}}[/tex]
Put all the values,
[tex]v=\sqrt{\dfrac{2\times 220}{1.6}}\\\\v=16.58\ m/s[/tex]
So, the speed of the bird is equal to 16.58 m/s.

Ở nhiệt độ không đổi, dưới áp suất 10^4 Pa l, một lượng khí có thể tích 10l. Tính thể tích lượng khí đó dưới áp suất 5.10^4 Pa
Answer:
Thể tích cuối cùng, V2 = 2 L
Explanation:
Cho các dữ liệu sau đây;
Khối lượng ban đầu = 10 L
Áp suất ban đầu = 10⁴ = 10000 Pa
Áp suất cuối cùng = 5 * 10⁴ = 50000 Pa
Để tìm tập mới hoặc tập cuối cùng, chúng ta sẽ sử dụng định luật Boyle;
Để tìm tập mới V2, chúng tôi sẽ sử dụng định luật Boyles.
Boyles phát biểu rằng khi nhiệt độ của khí lý tưởng được giữ không đổi, áp suất của khí tỉ lệ nghịch với thể tích mà khí chiếm giữ.
Về mặt toán học, định luật Boyles được đưa ra bởi;
[tex] PV = K[/tex]
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
Thay vào phương trình, ta có;
[tex] 10000 * 10 = 50000V_{2} [/tex]
[tex] 100000 = 50000V_{2} [/tex]
[tex] V_{2} = \frac {100000}{50000}[/tex]
[tex] V_{2} = 2 [/tex]
Thể tích cuối cùng, V2 = 2 L
what is the pressure exerted, what is the pressure exerted by 50kg girl as she places her weight on one shoe if the heels area is 0.002m²
Answer:
The pressure exerted by the girl is 245,000 N/m²
Explanation:
Given;
mass of the girl, m = 50 kg
area of the girl's shoe, A = 0.002 m²
The pressure exerted by the girl is calculated as follows;
[tex]P = \frac{F}{A} \\\\Where;\\F \ is \ the \ force \ exerted \ by \ girl's \ weight\\\\P = \frac{F}{A} = \frac{mg}{A} = \frac{50 \times 9.8}{0.002} = 245,000 \ N/m^2[/tex]
Therefore, the pressure exerted by the girl is 245,000 N/m²
A potential difference of 15 V produces a current of 0.60 amps in a piece of copper wire. What is the resistance of the wire?
9.0 Ω
18.0 Ω
25 Ω
Answer:
R = 25 Ohms
Explanation:
Given the following data;
Voltage (p.d) = 15 V
Current = 0.6 A
To find the resistance of the wire;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
[tex] R = \frac {V}{I} [/tex]
Substituting into the equation, we have;
[tex] R = \frac {15}{0.6} [/tex]
R = 25 Ohms
