Define unit of electric work (JOULE) in relation to quantity of charge and potential difference.

Answers

Answer 1

Answer: 1 volt = 1 joule per coulomb

It takes 1 joule of work to force a coulomb of charge enough closer to a charge
with the same sign to raise its potential 1 volt.

If you allow 1 coulomb of charge to fall to where its potential is 1 volt less,
it gives up 1 joule of energy.

Describe briefly how fossil fuels were formed

Answers

Fossil fuels are formed by organic remains that have been buried under rock. "Organic remains" can include animals and plants (think of oil and dinosaurs).

Fossil fuels were formed by the compression of dead plants and animals due to high pressure and temperature.
Some fossil fuels are coal, petroleum and natural gas

Sound waves travel fastest through the ground.

What is meant by a longitudinal wave ?

A longitudinal wave is a form of wave in which the medium vibrates parallel to the direction of the wave.

Here,

The displacement of the medium moves with the wave motion in the same direction.

Sound waves are longitudinal waves because, the direction of the energy transport is parallel to the oscillations of the sound waves.

Since, it is created by compressions and rarefactions in the air, sound waves are known as longitudinal waves. The air particles vibrate in a direction that is parallel to the direction of propagation.

The sound waves require a medium to propagate.

Solids and liquids have the quickest sound wave propagation rates, whereas gases have the slowest. Gases are very loosely packed while liquids are not as securely packed as solids. Sound moves through solids much more quickly than it does through gases due to the distance between the molecules.

Hence,

Sound waves travel fastest through the ground.

Answer: The correct option is the ground.

Explanation:

Sound is a longitudinal wave. In longitudinal wave, the particles vibrate parallel to the direction of the propagation of the wave.

It needs medium to travel. It can travel in solid, liquid and gas.

Sound wave travels faster in solid in comparison to liquid.

It travels slowest in air.

Ground is a denser medium. Here, the sound wave travels faster in comparison to the ocean and the air.

Therefore, the correct answer is the ground.

Suppose that we repeat the experiment shown in the video, but we replace one of the cylinders with a cylinder that has twice the radius (and use larger containers of water). If the height of the original cylinder is \rm h, how deeply must we submerge the new cylinder to get the same weight reduction as in the video?
