Need help please show steps and a thorough explanation so I can understand thank you in advance will rate.

1 0.25 points What is the half life of Cs (the isotope you will be working with in this lab)? Report your answer in years, but do not include units in the box below. 30 2 0.25 points The relationship between decay constant ()) and half life is t1/2 = In(2) For Cs-137, what is the value of the decay constant in units of years ? Do not type units into the box. Type your answer.. 3 0.05 points If you start at t = 0 with a decay rate of r = 10,000 Cs-137 decays per second, how many decays per second would you expect to find after 66.0 s? Type your answer. 4 0.05 points If you start at t = 0 with a decay rate of r = 10,000 Cs-137 decays per second, how many decays per second would you expect to find after 600 s? Type your answer. 5 0.05 points If you start at t = 0 with a decay rate of r = 10,000 Cs-137 decays per second, how many decays per second would you expect to find after 4800 s? Type your answer. 11:52 AM 8/13/2022 1
