Question

7. The Doppler shift formula for the frequency detected is f=rt where f I is the frequency emitted, v is the speed of sound, vD is the speed of the
detector, and vs is the speed of the source. Suppose the source is traveling at
5 m/s away from the detector, the detector is traveling at 7 m/s toward the
source, and there is a 3-m/s wind blowing from the source toward the
detector. The values that should be substituted into the Doppler shift
equation are:
A) VD = 7m/s and VS = 5m/s
D) VD = 10 m/s and vS = 2m/s
B) VD = 10 m/s and VS = 8m/s
E) VD = 4m/s and VS = 8m/s
C) VD = 4m/s and vs = 2m/s​

Answer 1

Answer:

c) VD=4m/s and vs =2m/s
