To solve a line cut by a transversal, use the properties of parallel lines, such as corresponding angles and alternate interior angles, to find the unknown angle measurements.
When a line is cut by a transversal, a number of simultaneous equations can be formed by using the properties of parallel lines. For example, the corresponding angles of the lines will always be equal, the alternate interior angles will be equal, and the consecutive interior angles will add up to 180 degrees. Using these properties, you can identify the unknown angle measurements. For example, if the measure of one of the corresponding angles is known, the measure of the other corresponding angle can be determined simply by using the fact that they are equal. Similarly, if one of the alternate interior angles is known, the other can be determined using the fact that they are equal. By forming these equations, you can solve for the unknown angle measurements.

What is the transfer of energy from a wave to the medium through which travels
Answer:
'Wave' is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.
Calculate the momentum elephant of a 2020 kg elephant charging a hunter at a speed of 7.49 m/s .
Answer:
15129.8 Kg•m/s
Explanation:
From the question given above, the following data were obtained:
Mass = 2020 kg
Velocity = 7.49 m/s
Momentum =?
Momentum is simply defined as the product of mass and velocity. Mathematically, it is expressed as:
Momentum = mass × velocity
With the above formula, we can obtain the momentum of the Elephant as follow:
Mass = 2020 kg
Velocity = 7.49 m/s
Momentum =?
Momentum = mass × velocity
Momentum = 2020 × 7.49
Momentum = 15129.8 Kg•m/s
Thus, the momentum of the Elephant is 15129.8 Kg•m/s

A sphere is released into the atmosphere where air resistance is present. As it falls it loses 7J of potential energy. How much kinetic energy did it gain?
Answer:
7 J
Explanation:
Given that,
A sphere is released into the atmosphere where air resistance is present.
The lose in energy is equal to 7 J
We need to find the gain in its kinetic energy.
We know that, as per the law of conservation of energy,
Loss in potential energy = gain in kinetic energy
⇒
Gain in kinetic energy = 7 J
Hence, the gain in kinetic energy is 7 J.

1.85s
1.92s
13.6s
3.69s
Explanation:
t = usin©/g
Where t is the time to reach the maximum height

An object has a weight of 1550N when it is on the surface of a planet of radius R. What will be the gravitational force on the object after it has been moved to a distance of 4R from the surface of the planet?
Answer:
W = 96.875 N
Explanation:
For this exercise let's use the law of universal gravitation
F = [tex]G \frac{m M }{r^2}[/tex]
we substitute this force in Newton's second law
F = m a
G \frac{m M }{r^2} = m a
a = [tex]G \frac{M}{r^2}[/tex]
This sidewalk we will call it gravity acceleration
g₀ = a
the weight of a body is
W₀ = m g₀
if we change the cario of r ’= 4r
a’= [tex]G \frac{M}{r'^2 }[/tex]
a ’= G \frac{M}{(4r)^2 }
a' = [tex]G \frac{M}{r^2} \ \frac{1}{16}[/tex]
a ’= [tex]\frac{g_o}{16}[/tex]
therefore the weight of the body must be
W = m g = [tex]m \ \frac{g_o}{16}[/tex]
W = W₀ / 16
W = 1550/16
W = 96.875 N
Compare and contrast hydrogen fuel cell vehicles with vehicles that have intemal combustion engines.
A hydrogen fuel cell vehicle is different from internal combustion engine as in fuel cell, hydrogen combines with oxygen whereas in internal combustion engines, gasoline is used.
What are hydrogen fuel cell vehicles and internal combustion engines?
In a internal combustion engine or fuel cell vehicle, the hydrogen fuel is combined with oxygen atom. While the combustion in a hydrogen- fuel or in a gasoline-powered engine is converted into mechanical energy, however in the hydrogen fuel cell vehicle, the chemical energy from the hydrogen and oxygen is converted into electrical energy.
Both hydrogen internal combustion engines and the hydrogen fuel cells can power vehicles using hydrogen, a zero-carbon fuel. Hydrogen engines burn hydrogen gas in an internal combustion engine, in the same way as the gasoline is used in a power engine. Examples of hydrogen internal combustion engines include gasoline engines, diesel engines, gas-turbine engines, and rocket-propulsion systems.

A 100 L ball is blown up inside at 200K. It is then taken outside in the hot sun, and the volume increases to 150 L. What is the new temperature?
Answer:
Temperature, T2 = 300 Kelvin
Explanation:
Given the following data;
Initial volume = 100 Liters
Initial temperature = 200 Kelvin
Final volume = 150 Liters
To find the final temperature T2, we would use Charles' law.
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles is given by;
[tex] \frac {V}{T} = K[/tex]
[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]
Making T2 as the subject formula, we have;
[tex] T_{2}= \frac{V_{2}}{V_{1}} * T_{1}[/tex]
Substituting into the formula, we have;
[tex] T_{2}= \frac{150}{100} * 200[/tex]
[tex] T_{2}= 1.5 * 200 [/tex]
Temperature, T2 = 300 Kelvin
A 12.0 volt battery is connected in a series to 4 identical 5.00 ohm resistors connected in parallel to each other. What is the current through the battery?
Answer:
9.6 Amperes
Explanation:
since the resistors are connected in parallel connection the equivalent resistance is1/R = 1 /5 + 1/5 + 1/5 + 1/5
solving for R we get 5/4 ohms
then from V=IR
I = V/R
I=12/(5/4)
hence I= 9.6 Amperes
A 12.0-volt battery is connected in a series, then the current through the battery is 9.6 A.
What are Resistors?Electrical resistance is implemented as a circuit element by resistors, which are passive two-terminal electrical components. Resistors are devices that are used in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biasing active components, and terminating transmission lines.
As part of motor controllers, power distribution systems, or as test loads for generators, high-power resistors that can dissipate many watts of electrical energy as heat may be used.
According to the question,
1/R = 1 /5 + 1/5 + 1/5 + 1/5
R = 5/4 ohms
By ohm's law,
V=IR
I = V/R
I=12/(5/4)
I= 9.6 Amperes

The equation below shows a general equation for a reaction, and the amounts of the substance are written underneath.
AB + CD → AC + BD
(15 g) (?) (?) (10 g)
The total mass of the products is 50g. Which best completes the other two amounts?
The amount of CD is 40 g, and the amount of AC is 35 g.
The amount of CD is 35 g, and the amount of AC is 40 g.
The amount of CD and AC would be the same.
The amount of CD and AC is undetermined.
Explanation:
The amount of CD is 35 g, and the amount of AC is 40 g.
Explanation:
AB + CD \rightarrow AC + BDAB+CD→AC+BD
The law of conservation of mass states that in any chemical reaction, the total mass of the reactants must be equal to the total mass of the products.
In this reaction, we know the mass of one reactant (AB, 15 g) and the mass of one product (BD, 10 g). In order to have the same total mass on the left side and on the right side of the equation, the mass of AC must be 5 g more than the mass of CD. We see that the only choice that satisfies this condition is:
The amount of CD is 35 g, and the amount of AC is 40 g.
In fact, if we assume these masses are correct, we have:
- on the reactant side: m(AB)+m(CD)= 15g + 35g = 50g
- on the product side: m(AC)+m(BD)= 40g + 10g = 50g
so, we have the same mass on both sides of the equation, and the law of conservation of mass is satisfied.
Answer:
B is the answer on edge
Explanation:
B: The amount of CD is 35 g, and the amount of AC is 40 g.
