As comparee to $$ ^{12}C $$ atom , $$ ^{14}C $$ atom has 

When number of nucleons in nuclei increases, the binding energy per nucleon:

The mass and energy equivalent to $$1$$ a.m.u, respectively are :

Which of the following is a wrong description of binding energy of a nucleus?

 A radioactive sample decays by $$63$$% of its initial value in $$10s$$. It would have decayed by $$50$$% of its initial value in

During $$\beta$$-decay:

Consider one of fission reactions of $$_{  }^{ 235 }{ U }$$ by thermal neutrons $$_{ 92 }^{ 235 }{ U }+n\rightarrow _{ 38 }^{ 94 }{ Sr }+_{ 54 }^{ 140 }{ Xe }+2n$$. The fission fragments are however unstable and they undergo successive $$\beta$$- decay until $$_{ 38 }^{ 94 }{ Sr }$$ becomes $$_{ 40 }^{ 94 }{ Zr }$$ and $$_{ 54 }^{ 140 }{ Xe }$$ becomes $$_{ 58 }^{ 140 }{ Ce }$$. The energy released in this process is
[Given: $$m(_{  }^{ 235 }{ U })=235.439u$$; $$m(n)=1.00866u$$; $$m(_{  }^{ 94 }{ Zr }=93.9064u$$; $$m(_{  }^{ 140 }{ Ce })=139.9055u$$; $$1u=931MeV$$]

$$1.00kg$$ of $$_{  }^{ 235 }{ U }$$ undergoes fission process. If energy released per event is $$200MeV$$, then the total energy released is

Calculate the binding energy of a deutron atom, which consists of a proton and a neutron, given that the atomic mass of the deuteron is $$2.014102u$$

The radioactivity of a sample is $${R}_{1}$$ at a time $${T}_{1}$$ and $${R}_{2}$$ at a time $${T}_{2}$$. If the half-life of the specimen is $$T$$, the number of atoms that have disintegrated in the time $$({T}_{2}-{T}_{1})$$ is proportional to
