Questions Related to electricity from nuclear energy

The energy released due to loss in mass during the process of nuclear fission and fusion is called:

physics towards green energy electricity from nuclear energy nuclear power nuclear energy

  1. hydro energy

  2. electrical energy

  3. nuclear energy

  4. geothermal energy

Show answer
Correct Option: C
Explanation:

The energy released due to a loss in mass during the process of nuclear fission and fusion is called nuclear energy. In both these processes, the loss in mass gets converted into energy in accordance with Einstein's mass-energy relation $E=mc^2$.

The most common fuel for a fission reaction in a nuclear reactor is:

Show answer
Correct Option: B
Explanation:

Uranium $238$ is used in nuclear reactor for fission reaction.

Energy produced in nuclear power plants is example of:

physics towards green energy electricity from nuclear energy nuclear power nuclear energy

  1. controlled nuclear fission.

  2. uncontrolled nuclear fission.

  3. controlled nuclear fusion.

  4. uncontrolled nuclear fusion.

Show answer
Correct Option: A
Explanation:

Nuclear fission carried out in a nuclear power plant is a controlled chain reaction which can be controlled to stop if required.

What is the biggest advantage of nuclear energy?

physics towards green energy electricity from nuclear energy nuclear power nuclear energy

  1. It is clean.

  2. Huge amount of energy is produced.

  3. The radioactive emissions from a nuclear power plant are healthy.

  4. Nuclear power plant can be easily set up in urban areas.

Show answer
Correct Option: B
Explanation:

The yield of nuclear energy is enormous and hence it has extraordinary potential as an energy source.

Health hazards related to nuclear radiations are:

  1. They can cause cancer.

  2. They can cause deformity in the body.

  3. They can damage the genes of a person.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

Nuclear radiations are extremely harmful to human health. They can cause:

1. The radiations can affect body cells and this may cause cancer.
2. The radiations have the capability to damage the genes of a person and this can be transferred to the next generation.
3. The radiations can cause permanent incurable deformity in human body.

What is Chain Reaction?

  1. Particles released by splitting of atom strikes other uranium atoms and split them.

  2. Particles released by expanding of atom strikes other uranium atoms and split them.

  3. Particles released by contracting of atom strikes other uranium atoms and split them.

  4. None

Show answer
Correct Option: A
Explanation:

A self sustaining reaction where the neutrons bombard an atom resulting in the fission process which leads to the release of more neutrons which then bombards more atoms and the cycles goes on.

What is known as process of splitting of an atom?

  1. Nuclear Fusion

  2. Nuclear Fission

  3. Nuclear Confusion

  4. Nuclear Dillusion

Show answer
Correct Option: B
Explanation:

Splitting of a large atomic nucleus into smaller particles is called nuclear fission.

Which energy is produced by nuclear fission or nuclear fusion?

From below which are the disadvantages of nuclear energy?

physics towards green energy electricity from nuclear energy nuclear power nuclear energy

  1. High set up cost

  2. low set up cost

  3. Waste products are useful

  4. None

Show answer
Correct Option: A
Explanation:

Energy generation from the nuclear energy is greater than from any non-conventional sources of energy. But it has some disadvantages too, such as:

1. Cost of nuclear power plant set up is very high.
2. Waste generated are hazardous to health and environment.
