a) Radon undergoes alpha decay with a half-life of 3.8 days. What is its decay constant in s^-1?

b) Sr -90 (A=90, Z = 38) decays via β^- decay. Calculate the energy of the antineutrino (in keV) if the beta particle has a kinetic energy of 397 keV. Note - you can look the atomic masses up online.

c) What is the average binding energy per nucleon for Argon-40 (A=40, Z = 18) in MeV/nucleon? Note - keep 4 significant figures.
