Problem

A certain unstable nucleus created in a laboratory experiment is found to occupy a volume of 7.2×10−44 m37.2\times10^{-44}\,\text{m}^3 just at the instant of its formation. (a) Determine the radius of the nucleus corresponding to this volume. (b) Using R0=1.2×10−15 m,R_0=1.2\times10^{-15}\,\text{m}, estimate the mass number AA of the nucleus. (c) Hence calculate the mass of the nucleus in kilograms, taking 1 u=1.66×10−27 kg.1\,\text{u}=1.66\times10^{-27}\,\text{kg}.
