(a) Calculate the minimum safe distance (in m) you can be from a speaker that puts out 1.20 W of sound, using the following assumptions. The sound power spreads uniformly over a sphere of radius r and area 4?r2, your eardrum area is 0.720 cm2, and it cannot tolerate more than 1.00 ? 10?6 W. Damage is done by this small amount of power after prolonged exposure and can be repaired by the body, but damage done by 10?4 W...
