The binding energy per nucleon for deuteron $(_1H^2)$ and helium $(_2He^4)$ are $1.1 \, MeV$ and $7 \, MeV$ respectively. When two deuterons fuse to form a helium nucleus,the energy released is ........... $MeV$.

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

The binding energy of deuteron $_1^2H$ is $1.112 \, MeV$ per nucleon and an $\alpha$-particle $_2^4He$ has a binding energy of $7.047 \, MeV$ per nucleon. Then in the fusion reaction $_1^2H + _1^2H \to _2^4He + Q$,the energy $Q$ released is ........ $MeV$.

During the fission of $_{92}U^{235}$,$0.1\%$ of its mass is converted into energy. How much energy is produced from $1 \, kg$ of $_{92}U^{235}$?

Which of the following nuclei undergoes fission when bombarded with slow neutrons?

Explain the process of thermonuclear fusion as a source of energy in the Sun and stars.
