Calculate the elastic potential energy per unit volume of water at a depth of `1km`. Compressibility (`alpha`) of water `=5xx10^(-10)` SI units. Density of water `=10^(3)kg//m^(3)`

Explanation

To calculate the elastic potential energy per unit volume of water at a depth of 1 km, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Elastic Potential Energy per Unit Volume**:
The elastic potential energy (U) per unit volume can be expressed as:
\[
U = \frac{1}{2} \times \text{Stress} \times \text{Strain}
