Pls answer this question 15.
A point like sound source emits sound in all direction uniformly. An observer is at a distance
of 50rn from the source detects sound of intensity watt/m2. If the butk modulus of air is
1.6 10s N\m2 and velocity Of sound is 340 rn/s. Find power developed by sound source and
pressure amplitude at the position Of observer.
