How much should the temperature of a brass rod be increased so as to increse its length by `1%`? Given `alpha` for brass is `0.00002 .^(@)C^(-1)`.

Explanation

To determine how much the temperature of a brass rod should be increased to achieve a 1% increase in its length, we can use the formula for linear expansion. The formula is given by:

\[ \Delta L = L \cdot \alpha \cdot \Delta T \]

Where:
- \(\Delta L\) = change in length
