What is the intensity at radial distances (a) 2.50 m and (b) 6.00 m from an isotropic point source of sound that emits energy at the rate 12.0 W, assuming no energy absorption by the surrounding air?

Explanation

To solve the problem of finding the intensity at radial distances of 2.50 m and 6.00 m from an isotropic point source of sound emitting energy at a rate of 12.0 W, we will follow these steps:

### Step 1: Understand the concept of intensity
Intensity (I) is defined as the power (P) per unit area (A). For a point source emitting sound isotropically, the sound spreads out uniformly in all directions, forming a sphere around the source.

### Step 2: Write the formula for intensity
The formula for intensity is given by:
\[ I = \frac{P}{A} \]
