Question

The normal mode of a resonating system is sinusoidally disturbed at a frequency $f$. Assume that $\gamma<<f_{0}$, where $f_{0}$ is the normal mode's natural frequency.
-(b) If $f$ is about $30 f_{0}$ ?
A) Roughly zero
B) Roughly $A_{0} / 30$
C) Roughly $A_{0} / 1.4$
D) Roughly $A_{0}$
E) Roughly $1.4 \mathrm{~A}_{0}$
F) Roughly $30 A_{0}$
G) Other (specify)

When the frequency of disturbance $f$ is much higher than the natural frequency $f_0$ (in this case, $f = 30f_0$), the system cannot respond effectively to such rapid oscillations. Therefore, the amplitude of the system's response is roughly zero, as it cannot keep up with the high frequency of disturbance.
