Compute all parts of given question:
Question: A factory whistle emits sound of frequency 720 Hz.
Part I: When the wind velocity is 12.1m/s from the north, what frequency will observers here who are located, at rest, due north of the whistle? Assume T=20 µC.
Part II: What frequency will observers here who are located, at rest, due south of the whistle?
I am not able to get the correct answer please help me for above question.
