(C) The equation for a damped harmonic oscillator is given by $x(t) = A e^{-bt/2m} \cos(\omega' t + \delta)$,where $A$ is the initial amplitude,$b$ is the damping constant,$m$ is the mass,$\omega'$ is the damped angular frequency,and $\delta$ is the initial phase.During damping,the amplitude $A e^{-bt/2m}$ decreases exponentially with time.The damped angular frequency $\omega' = \sqrt{\frac{k}{m} - \frac{b^2}{4m^2}}$ is different from the natural frequency $\omega_0 = \sqrt{\frac{k}{m}}$,and the time period $T = \frac{2\pi}{\omega'}$ also changes.The initial phase $\delta$ is determined by the initial conditions (position and velocity at $t = 0$) and remains constant regardless of the damping process.

Which of the following quantities does $NOT$ change due to the damping of oscillations?

In forced oscillation of a particle,the amplitude is maximum for a frequency $\omega_{1}$ of the driving force,while the energy is maximum for a frequency $\omega_{2}$ of the driving force. Then:

The displacement of a damped oscillator is $x(t) = \exp(-0.2 t) \cos(3.2 t + \Phi)$,where $t$ is time in seconds. The time required for the amplitude of the oscillator to become $\frac{1}{e^{1.2}}$ times its initial amplitude is (in $s$)
