For a uranium nucleus, how does its mass vary with volume?

An atom ${}_3^8 X$ is bombarded by a shower of fundamental particles. In $10 \ s$,this atom absorbs $10$ electrons,$10$ protons,and $9$ neutrons. The percentage growth in the surface area of the nucleus is recorded as: (in $\%$)

The range of weak nuclear force is of the order of

The radius of germanium $(Ge)$ nuclide is measured to be twice the radius of ${ }_4^9 Be$. The number of nucleons in $Ge$ will be

The ratio of the nuclear radii of the gold isotope ${}_{79}^{197}Au$ and the silver isotope ${}_{47}^{107}Ag$ is $ . . . . . . $.

The mass number and the volume of a nucleus are $A$ and $V$ respectively. If the mass number is increased to $2A$,then the volume changes to:
