A) \[1020\text{ }Hz\]
B) \[1110\text{ }Hz\]
C) \[2040\text{ }Hz\]
D) \[610\text{ }Hz\]
Correct Answer: B
Solution :
Apart frequency \[n'=n\left[ \frac{v+{{v}_{0}}}{v} \right]\] \[n'=1020\left[ \frac{340+30}{340} \right]\] \[n'=1020\times 108.8\] \[n'=1110\,Hz\]You need to login to perform this action.
