A straight line source of sound of length `L=10m`, emits a pulse of sound energy (in mW) is intercepted by an acoustic cylindrical detector of surface area `2.4cm^2`. Located at a perpendicular distance 7 m from the source ? The waves reach perpenduculary at the surface of the detector. The total emiited by the source in the form of sound is `2.2xx10^(4)W`. (use `pi=22//7`)

Explanation

To solve the problem, we need to calculate the power received by the acoustic cylindrical detector from the straight line source of sound. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the parameters given
- Length of the sound source, \( L = 10 \, \text{m} \)
- Distance from the source to the detector, \( r = 7 \, \text{m} \)
- Surface area of the detector, \( A = 2.4 \, \text{cm}^2 = 2.4 \times 10^{-4} \, \text{m}^2 \)
- Total power emitted by the source, \( P = 2.2 \times 10^4 \, \text{W} \)
