Calculate and compare the energy released by (a) fusion of 1.0kg of hydrogen deep within the sun, and (b) the fission of 1.0kg of `U^(235)` in a fission reactor.

Explanation

To solve the problem of calculating and comparing the energy released by the fusion of 1.0 kg of hydrogen and the fission of 1.0 kg of uranium-235, we can follow these steps:

### Step 1: Calculate the energy released by the fusion of 1.0 kg of hydrogen.

1. **Identify the fusion reaction**: The fusion of hydrogen can be represented as:
\[ 4 \, ^1H \rightarrow \, ^4He + 2e^+ + 2\nu_e \]
