Nuclei of a radioactive element A are being produced at a constant rate α . The element A has a decay constant λ . At time t=0 , there are N0 nuclei of element A .
a. Calculate the number of nuclei ( N ) of A at any time t .
b. If α=2λN0 , calculate the number of nuclei of A after one half-life of A and also the limiting value of N as t→∞ .
