Answer 2

Answer:

Explanation:

Detailed answer :-

If an external force with angular frequency Wd acts on an oscillating system with natural angular frequency W , the system oscillates with angular frequency Wd.The amplitude of oscillations is the greater when

=> Wd = W

A condition called RESONANCE.
