Suppose that a public address system emits sound uniformly in all directions and that there are no reflections. The intensity at a location 27 m away from the sound source is 3.0 X 10^{-4} W/m^{2}. What is the intensity at a spot that is 80 m away?

Step 1

The formula for the intensity in terms of po...
