The binding energies per nucleon in case of deutron `("-1H^2)` and `alpha`-particle `("-2He^4)` are 1.25 MeV and 7.2 MeV respectively. Which nucleus is more stable?

The nucleus of an atom of ._(92)Y^(235) initially at rest decays by emitting an alpha particle. The binding energy per nucleon of parent and dougther nuclei are 7.8MeV and 7.835MeV respectively and that of alpha particles is 7.07MeV//"nucleon". Assuming the dougther nucleus to be formed in the unexcited state and neglecting its share of energy in the reaction, calculate speed of emitted alpha particle. Take mass of alpha particle to be 6.68xx10^(-27)kg .

A heavy nucleus P of mass number of 240 and binding energy 7.6 MeV per nucleon splits into two nuclie Q and R of mass numbers 110 and 130 and binding energy per nucleon 8.5 MeV and 8.4 MeV, respectively. Calculate the energy released in the fission.

The binding energy per nucleon of _2He^4 is 7.075 MeV. If the masses of prton and neutron are 1.007270 a.m.u. and 1.008665 a.m.u. respectively,find the mass of _2He^4 nucleus.

The pH of same concentration of gastric juice and lemon juice are 1.5 and 2.4 respectively. Which is more acidic?

The binding energy per nucleon of _2He^4 is 7.075 MeV. What is its total binding energy?

Calculate mass defect, binding energy and binding energy per nucleon of deuteron ( "_1H^2 ) nucleus. Given mass of proton=1.007275 a.m.u., mass of neutron = 1.008665 a.m.u. and mass of deuteron =2.013553 a.m.u.
