Nuclei Test - 4...

The binding energy per nucleon of $$_5B^{10}$$ is $$8.0$$MeV and that of $$_5B^{11}$$ is $$7.5$$MeV. The Energy required to remove a neutron from $$_5B^{11}$$ is (mass of electron and proton are $$9.11\times 10^{-31}$$kg and $$1.67\times 10^{-27}$$kg).

Two radioactive sources $$X$$ and $$Y$$ of half lives $$1h$$ and $$2h$$ respectively initially contain the same number of radioactive atoms. At the end of $$2h$$, their rates of disintegration are in the ratio of :

The mass defect of $$_{ 2 }^{ 4 }{ He }$$ is $$0.03 u$$. The binding energy per nucleon of helium (in $$MeV$$) is

Atomic weight of boron is $$10.81$$ and it has two isotopes $$_{5}B^{10}$$ and $$_{5}B^{11}$$. Then ratio of $$_{5}B^{10} : \,_{5}B^{11}$$ in nature would be

Nuclear reactor in which $$U - 235$$ is used as fuel. Uses $$2\ kg$$ of $$U-235$$ in $$30$$ days. Then, power output of the reactor will be (given energy released per fission $$= 185\ MeV$$).

The binding energy per nucleon of $$C^{12}$$ is $$E_{1}$$ and that of $$C^{13}$$ is $$E_{2}$$. The energy required to remove one neutron from $$C^{13}$$ is

A nucleus X initially at rest, undergoes alpha decay according to the equation.
$$_{92}X^A\rightarrow _{Z}Y^{228}+\alpha$$.
Then, the value of A and Z are.

Li nucleus has three protons and four neutrons. Mass of lithium nucleus is 7.03.6005 amu. Mass of proton is 1.007277 amu and mass of neutron is 1.008665 amu. Mass defect for lithium nucleus in amu is 

Nucleus of mass number $$A$$, originally at rest, emits the $$\alpha$$ particle with speed $$v$$. The daughter nucleus recoils with a speed of :

The binding energy per nucleon of deuteron $$(_{1}H^{2})$$ and helium $$(_{2}He^{4})$$ are $$1.1\ MeV$$ and $$7.0\ MeV$$, respectively. The energy released when two deuterons fuse to form a helium nucleus is
