Explanation / Answer

he low-frequency speaker of a stereo set has a surface area of 0.05 m^2 and produces 1 W of acoustical power.

A) what is the intensity at the speaker?

answer= 20.0 W/m^2

B) if the speaker projects sounds uniformly in all directions, at what distance from the speaker is the intensity 0.1 W/m^2?

answer= 0.892 m
