A) 0.5 Hz
B) 1.0 Hz
C) \[\frac{\pi }{2}Hz\]
D) \[\pi \,Hz\]
Correct Answer: A
Solution :
Comparing given equation with standard equation, \[x=a\cos \,(\omega t+\varphi )\] we get, \[a=0.01\] and\[\omega =\pi \] \[\Rightarrow 2\pi n=\pi \Rightarrow n=0.5\,Hz\]You need to login to perform this action.
