Fusion sequence total energy

In a second version of the same nuclear physics investigation, a simplified fusion sequence in a nuclear reactor model releases \(24\,\text{MeV}\) per completed step. Calculate the total energy from \(4\) completed steps. Use the diagram first, then calculate the requested value. Enter the numerical result and choose the interpretation that matches the nuclear physics meaning.
