PHY 1120 Homework 13 Nuclear Physics and Radioactivity 1. A pi meson subatomic particle has a mass of 139 MeV/c2. What is this mass in unified atomic mass units (u)? 2. Use the figure provided to estimate the total binding energy of gg Kr. Binding energy per nucleon (MeV) 0 50 100 150 200 250 Number of nucleons, A (mass number) 3. Calculate the total binding energy (in MeV) and the binding energy per nucleon for ; Li The mass of a proton bound in a nucleus with an electron is an H atom (get mass for this and for a neutron from attached table). The mass of; Liis 7.016003
