Show that nuclear density is almost constant for nuclei with `Zgt10`.

Explanation

Nuclear density, `rho` = (mass of the nuclei)/(Volume of the nuclei) = `(A.m)/((4)/(3) pi R_(0)^(3)A) = (m)/(4/3 pi R_(0)^(3))`
`rho = (1.67 xx 10^(-27))/(4/3 pi xx (1.2 xx 10^(-15))^(3)) = 2.3 xx 10^(17) kg m^(-3)`
The expression shows that the nuclear density is independent of the mass number A.In other words, all the nuclei `(Z gt 10)` have the same density and it is important characteristics of the nuclei.
