AP Physics 2
15.7 Fission, Fusion, and Nuclear Decay
Sample X contains \(N_0\) undecayed nuclei of a radioactive isotope with a half-life of \(T_0\). Sample Y contains \(3N_0\) undecayed nuclei of a different radioactive isotope with a half-life of \(2T_0\). What is the ratio \(R_X / R_Y\) of the initial decay rate (activity) of Sample X to the initial decay rate of Sample Y?
