Solve the following system of equations: (15)/u+2/v=17 ,\ \ \ 1/u+1/v=(36)/5

Solve the following system of equations: (15)/(u)+(2)/(v)=17,quad (1)/(u)+(1)/(v)=(36)/(5)

Calculate the B.E./nucleon of ._17Cl^(35) nucleus. Given that of proton =1.007825u , mass of neutron =1.008665 u , mass of ._17Cl^(35)=34.980000u , 1u=931MeV .

Calculate the binding energy per nucleon of ._17^35Cl nucleus. Given that mass of ._17^35Cl nucleus = 34.98000 u, mass of proton = 1.007825 u, mass of neutron = 1.008665 u and 1 u is equivalent to 931 Mev.

The decay rate of a radioactive sample is called its activity. The half life of U_92^238 against alpha decay is 1.5x 10^17s . Calculate the activity of a sample of U_92^238 having 25 x 10^21 atoms.
