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 betaparticle has a kinetic energy of 397 keV. Note - you can look theatomic 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 significantfigures.
