Embibe Experts Solutions for Chapter: Nuclei, Exercise 1: Exercise

Compare the radii of the nuclei of masses numbers $27 \mathrm{and} 64$

The radius of oxygen nucleus ${}_8{}^{16}\mathrm{O}=2.8\times {10}^{-12 }\mathrm{m}$. Find the radius of lead nucleus ${}_{82}{}^{205}\mathrm{Pb}$.

Compare the radii of the nuclei of mass numbers $27$ and $64$.

$200 \mathrm{MeV}$ energy is released when one nucleus of ${\mathrm{U}}^{235}$undergoes fission. Find the number of fission per second required for producing power of $1 \mathrm{megawatt}$.

How much ${{\mathrm{U}}^{235}}^{}$is consumed in a day in an atomic house operating at $400 \mathrm{MW}$, provided that whole of mass of uranium is converted into energy?

Energy released per fission of nucleus is of the order of $200 \mathrm{MeV}$ whereas that perfusion is of the order of $10 \mathrm{MeV}$. But a fusion bomb (hydrogen bomb) is said to be more powerful than a fission bomb. Explain why? 

What is an exoergic nuclear reaction?

What is proton-proton cycle?
