The activity of sample A is 16 Ci and that of sample B is 4.0 Ci. After

Question:

The activity of sample A is 16 Ci and that of sample B is 4.0 Ci. After 8.0 days the two samples have the same activity of 0.25 Ci.

(a) Is the half-life of type A nuclei greater than, less than, or the same as the half-life of type B nuclei?

(b) Calculate the half-lives of type A and type B nuclei.
