Question: The kinetic energy of a positron emitted from the ß+ decay of a 13N nucleus into a 13C nucleus is measured to be 1.195MeV.
Part A: What is the energy of the accompanying neutrino of the decay process?
I need help to solve the above question and neglect the recoil energy of the daughter nucleus. Answer must be in keV.
The Earth can be approximated as a sphere of uniform density, rotating on its axis once a day. The mass of the Earth is 5.97×1024 kg, the radius of the Earth is 6.38×106 m, and the time of rotation for the Earth is 24.0 hrs.
