Answers Key:

Generic 3

5 x 3 = 15

Time period of a loaded spring,
T = 2\(\pi \sqrt { \frac { m }{ k } } \)
As T is independent of g, will not be affected when the loaded spring is taken to the moon.

At a particular speed, the frequency of the engine of the bus becomes equal to the natural frequency of the body of the bus the frame of the bus begins to vibrate strongly clue to resonance.

(i) A large amplitude in all directions. As these sound waves strike the glass 'windows, they set them into forced oscillations.
(ii) Since glass is brittle, so the glass windows break as soon as they start- oscillating due to forced oscillations.

When the natural frequency of the wire glass becomes equal to that of the singers voice, the resulting resonance due to the powerful voice of the singer may break the glass.

The resonance may cause disaster during the earthquake, if the frequency of oscillation present within the earth per chance coincides with natural frequency of some building, which may start vibrating with large amplitude due to resonance and may get damaged.
