Sole the all parts of given problem:
Problem: A point source emits 45.2 W of sound isotropically. A small microphone intercepts the sound in an area of 0.245 cm2, 280 m from the source.
Part A: Calculate the sound intensity there?
Part B: Calculate the power intercepted by the microphone?
If possible just a brief explanation how you got the answer for above problem?
