C Correct answer
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 $E=mc^2$.

A Correct answer
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.

From below which are the disadvantages of nuclear energy?

  1. High set up cost

  2. low set up cost

  3. Waste products are useful

  4. None
Reveal answer Fill a bubble to check yourself
A Correct answer
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.
