A microphone in the ocean is sensitive to the sounds emitted by dolphins. To produce a usable signal, sound waves striking the microphone must have an intensity of 1.02 *10-11 W/m². If dolphins emit sounds with a power of 0.049 9 W, how far away can a dolphin be and still be heard? Disregard absorption of sound waves by the water.
