A) \[540\,m{{s}^{-1}}\]
B) \[5.4\,m{{s}^{-1}}\]
C) \[0.184\,m{{s}^{-1}}\]
D) \[9\,m{{s}^{-1}}\]
Correct Answer: D
Solution :
Frequency, \[n=\frac{54}{60}\] \[\Rightarrow \] \[n=\frac{9}{10}\] \[\therefore \]velocity, \[v=n\lambda \] \[=\frac{9}{10}\times 10=9m/s\]You need to login to perform this action.
