The control rod in a nuclear reactor is made of

In an atomic bomb,the energy is released due to

Fission of nuclei is possible because the binding energy per nucleon in them

When a slow neutron goes sufficiently close to a ${U^{235}}$ nucleus,then the process that takes place is

The fission of a $_{92}U^{235}$ nucleus releases $200 \, MeV$ of energy. Find the rate of fission of $_{92}U^{235}$ required to operate a reactor at a constant power of $5 \, W$.

$1 \, g$ of hydrogen is converted into $0.993 \, g$ of helium in a thermonuclear reaction. The energy released is
