If the pitch of the sound of a source appears to drop by 10%to a moving person, then determine the velocity of motion of the person. Velocity of sound = 330 ms ^(-1).

1.	If the pitch of the sound of a source appears to drop by 10%to a moving person, then determine the velocity of motion of the person. Velocity of sound = 330 ms ^(-1).
Answer» SOLUTION :APPARENT FREQ. `v.=((v-v_(0))/v)v or (v.)/v=900/1000=9/10,v=330ms^(-1) therefore 9/10=330-v_(0)=9/10**330=297 v_(0)=330-297=(33M)/s.`
