Explain fusion and stellar energy processes

Paper 1, Paper 2 5 marks Difficulty 5

Fusion sequence total energy

A simplified fusion sequence in a neutron chain reaction diagram releases \(33\,\text{MeV}\) per completed step. Calculate the total energy from \(6\) completed steps. Enter the numerical result and choose the interpretation that matches the nuclear physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
