The Sun radiates energy continuously and maintains its brightness because:

Energy released in the fission of a single $_{92}U^{235}$ nucleus is $200 \, MeV$. The fission rate of a $_{92}U^{235}$ fuelled reactor operating at a power level of $5 \, W$ is

When Uranium is bombarded with neutrons,it undergoes fission. The fission reaction can be written as ${}_{92}U^{235} + {}_0n^1 \to {}_{56}Ba^{141} + {}_{36}Kr^{92} + 3x + Q$,where three particles named $x$ are produced and energy $Q$ is released. What is the name of the particle $x$?

In an $\alpha$-decay,the kinetic energy of the $\alpha$-particle is $48 \, MeV$ and the $Q$-value of the reaction is $50 \, MeV$. The mass number of the mother nucleus is:

Which of the following is used as a moderator in nuclear reactors?

$A$ power of $100 \ W$ is produced by the fission of $1 \ kg$ of $^{235}U$. For approximately how long will the energy production continue?
