1. The problem statement, all variables and given/known data Two unstable isotopes A and B and a stable isotope C have the following decay rates per atom present: Let rate = k, A > B, k=k1=3 atoms/sec A > C, k=k2=1 atom/sec B > C, k=k3=2 atoms/sec Intially, there are N0 atoms of species A present, but none of other two types. Using Laplace transforms, find the number of atoms of type C present at a later time t 2. Relevant equations 3. The attempt at a solution dA/dt = -kA, A(0,t) = N0 1/A dA = -kdt ∫1/A dA = ∫-kdt ln A = -kt + C A = e-kt+C A = De-kt A = N0e-kt then... i dont know.... Please help.. thank you!!!
