A circular plate of area `0.4 cm^(2)` is kept at distance of `2m` source of power `piW`. Find the amount of energy received by plate in `5` secs.

Explanation

To solve the problem step by step, we will follow the instructions given in the video transcript.

### Step 1: Identify the given values
- Area of the circular plate, \( A = 0.4 \, \text{cm}^2 \)
- Distance from the source, \( d = 2 \, \text{m} \)
- Power of the source, \( P = \pi \, \text{W} \)
- Time duration, \( T = 5 \, \text{s} \)
