AI Generated Solution

To understand where the mass difference comes from when nucleons are separated from a nucleus, we can break down the explanation into the following steps: ### Step-by-Step Solution: 1. **Understanding Nucleons and Mass**: - Nucleons (protons and neutrons) are the building blocks of a nucleus. When they are bound together in a nucleus, they exhibit a certain mass. 2. **Mass of Separated Nucleons vs. Mass of the Nucleus**: ...
