Vedclass · Answer

(C) simple pendulum oscillating in air experiences air resistance (damping force).The damping force acts opposite to the direction of motion,which causes the energy of the oscillator to dissipate over time.As a result,the amplitude $A$ of the oscillation gradually decreases.For a damped harmonic oscillator,the time period $T'$ is given by $T' = \frac{2\pi}{\sqrt{\omega_0^2 - b^2/4m^2}}$,where $b$ is the damping constant. As damping occurs,the effective frequency decreases,which means the time period $T$ increases.Therefore,as time passes,$T$ increases and $A$ decreases.

$A$ simple pendulum oscillates in air with time period $T$ and amplitude $A$. As the time passes,
