The figure shows the decay of parents in a radioactive sample. The axes are scaled by Ns = 2.02 x 10 and ts = 10.0 s. What is the activity of the sample at t = 28.7 s? NN 0 Number i UnitsA nucleus with mass number 231 emits a 3.838 MeV alpha particle. Calculate the disintegration energy Q for this process, taking the recoil energy of the residual nucleus into account. nits A free neutron decays to a proton, an electron, and an antineutrino. If the neutron-hydrogen atom mass difference is 840 pu, what is the maximum kinetic energy Kmnax possible for the electron produced in a neutron decay? Number n Units
