The graph of binding energy per nucleon $B_N$ versus mass number $A$ is given. In which process will energy be released?

Find the binding energy per nucleon for $^{120}_{50}Sn$. Given: mass of proton $m_{p} = 1.00783 \, U$,mass of neutron $m_{n} = 1.00867 \, U$,and mass of tin nucleus $m_{Sn} = 119.902199 \, U$. (Take $1 \, U = 931 \, MeV$) (in $, MeV$)

What is the energy equivalent to one kilogram of mass?

State Einstein's special theory of relativity and provide the mass-energy equivalence formula.

The ratio of the orders of the spacings of nuclear energy levels and atomic energy levels is

$A$ radioactive nucleus has specific binding energy $E_{1}$. It emits an $\alpha$-particle. The resulting nucleus has specific binding energy $E_{2}$. Then
