A) 500 Hz
B) 550 Hz
C) 355 Hz
D) 55.5 Hz
E) None of these
Correct Answer: B
Solution :
Hence, \[n=500\,Hz,\]\[{{v}_{0}}=0,\] \[{{v}_{s}}=30\,m\text{/}s,\]\[v=330\,m\text{/}s\] \[\therefore \] From, \[n=n\left( \frac{v-{{v}_{0}}}{v-{{v}_{s}}} \right)\] \[=500\left( \frac{330}{330-30} \right)\] \[=500\,Hz\]You need to login to perform this action.
