Total nuclear energy from repeated events

Each completed nuclear event in a mass defect calculation releases \(189\,\text{MeV}\). Calculate total energy from \(3\times10^{12}\) events in units of \(10^{12}\,\text{MeV}\). Use the diagram labels before calculating the requested value. Enter the numerical result and choose the interpretation that matches the quantum or nuclear physics.
