A) 600 Hz
B) 585 Hz
C) 645 Hz
D) 666 Hz
Correct Answer: D
Solution :
[d] \[v'=v\left( \frac{v+{{v}_{D}}}{v-{{v}_{S}}} \right)\] Here, \[v=600Hz,\,\,{{v}_{D}}=15m/s\] \[{{v}_{s}}=20,m/s,\,\,\,\,v=340m/s\] \[\therefore \,\,\,\,v'=600\left( \frac{355}{320} \right)\approx 666\,Hz\]You need to login to perform this action.
