Answer:

Option (B)

Explanation:

The latent heat is often defined as the amount of temperature that is needed in the conversion of a phase, such as from solid to liquid (or gas) or from liquid to gas, and during this entire process, the temperature remains constant.

This latent heat plays an important role in generating intensive thunderstorms as well as hurricanes because it acts as a source of energy.

There are two types of latent heat and they are as follows-

(1) Latent heat of fusion- This involves a phase change from solid to liquid.

(2) Latent heat of vaporization- This involves a phase transformation from liquid to gas.

Thus, the correct answer is option (B).

What is the original source of energy for gasoline?
Yuki888 [10]
Gasoline comes from petroleum, which is a fossil fuel. Petroleum, coal and natural gas (methane) are all made in the earth's crust from the bodies of plants and animals that died long ago. That's why they are called fossil fuels.

The sun provides the energy that all life needs to grow and reproduce. Therefore, fossil fuels can be considered a form of solar energy that has been stored in the bodies of living things, and then concentrated in hydrocarbon deposits in the earth's crust.

The fact is that all the energy on earth comes from the sun, directly or indirectly, except for nuclear energy, which comes from radioactive elements that were made in other stars that existed before the sun.

Hope this helps!!!

A boat with a horizontal tow rope pulls a water skier. She skis off to the side, so the rope makes an angle of 12.0 ∘ with the f
Sladkaya [172]

Answer:

62.601kJ

Explanation:

We have a force with a horizontal component given by the angle of 15°. So wue can take this component to calculate the total work done, that is,

W_T = Fd(cos\theta)

Our values are,

d=320m

Angle = 12\°

Force=200N,

Substituting in Work equation,

W_T = 200(320)(cos12)

W_T = 62601.4J

W_T = 62.601kJ

Earthquakes typically occur
ICE Princess25 [194]

Answer:

<h3><u><em>Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. ... When the rocks break, the earthquake occurs.</em></u></h3>
