A) \[510\,Hz\]
B) \[500\,Hz\]
C) \[525\,Hz\]
D) \[550\,Hz\]
Correct Answer: C
Solution :
[c] Apparent frequency \[n'=n\frac{(u+{{v}_{w}})}{(u+{{v}_{w}}-{{v}_{s}}\,\cos \,60{}^\circ )}\] \[=\frac{510(330+20)}{330+20-20\,\cos \,60{}^\circ }\] \[=510\times \frac{350}{340}=525\,Hz\]You need to login to perform this action.
