(a)

The energy released in each fusion cycle of 4 protons into a is

The number of protons in 1.0 kg of hydrogen is

Therefore, the total energy that will be released in fusion of 1.0 kg of hydrogen will be

(b)

We will assume that the average energy released per fission of is 200 MeV.

The number of atoms in 1.0 kg of uranium will be

The energy that will be released in fission of 1.0 kg of in a nuclear reactor will be
