State the principle of an atomic bomb and identify the nuclear process that occurs within it.

When $^{235}_{92}U$ is bombarded with one neutron,fission occurs and the products are three neutrons,$^{94}_{36}Kr$ and:

What is the amount of $U^{235}$ in $kg$ consumed per hour in a nuclear reactor of $100 \, kW$ capacity? (Given $E_s = 200 \, MeV/fission$)

In the fusion reaction,${ }_1 H^2+{ }_1 H^2 \rightarrow{ }_2 He^4+Q$,where $Q$ is the energy released. If $c$ is the speed of light and $m$ is the mass of each deuterium nucleus,then the mass of the helium nucleus formed is:

How can fusion reactors provide unlimited power to humanity?

The energy released per fission of a nucleus of ${}^{240}X$ is $200 \ MeV$. The energy released if all the atoms in $120 \ g$ of pure ${}^{240}X$ undergo fission is $........ \times 10^{25} \ MeV$. (Given $N_A = 6 \times 10^{23}$)
