To solve the problem of finding the number of nuclei of a radioactive substance A and the stable substance B at any time t, we can follow these steps: ### Step 1: Define the Variables Let: - \( N_A(t) \) = number of nuclei of substance A at time \( t \) - \( N_B(t) \) = number of nuclei of substance B at time \( t \) - \( \alpha \) = rate of production of A (constant) - \( \lambda \) = decay constant of A ...
