(1 Point)
a) Restoring
b) Frictional
c) External Periodic
d) All​

Answer 1

Answer:

A periodic force driving a harmonic oscillator at its natural frequency produces resonance. The system is said to resonate. The less damping a system has, the higher the amplitude of the forced oscillations near resonance. The more damping a system has, the broader response it has to varying driving frequencies
