Answer 1

APPLICATIONS OF RESONANCE IS :

• Resonance can be employed to maintain AC circuit oscillations at a constant frequency, just as a pendulum can be used to maintain constant oscillation speed in a timekeeping mechanism.

• One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other.

Answer 2

Answer:

(1) A radio or TV receiver set is tuned to the frequency of the desired broadcast station by adjusting the resonans frequency of its electrical oscillator circuit.

(2) The speed of sound at room temperature can be determined by making the air column of a resonance tube resonate with a vibraing tuning fork of known requency.

(3) The frequency of a tuning fork can be determined by making a sonometer wire, of known mass per unit length and under known tension, resonate with the vibrating fork.

(4) The amplitude of the oscillations of a child on a SWing is increased by pushing with a frequency equal to the natural frequency or the swing
