A) frequency equal to \[\frac{15}{\pi }Hz\]
B) velocity equals to 30 m/s along -ve direction
C) time period of oscillation equal to \[\frac{\pi }{15}s\]
D) wavelength equal to \[2\pi \]metres
Correct Answer: B
Solution :
Given equation may be written as \[y=5\sin 60\left( t+\frac{x}{30} \right)\] ...(i) The standard equation is \[y=a\sin \omega \left( t-\frac{x}{\upsilon } \right)\] ...(ii) Now, comparing equation (i) and (ii) we have \[\frac{x}{30}=-\frac{x}{\upsilon }\] or \[\upsilon =-30m/s\]You need to login to perform this action.
