Ten questions. The result tells you which lessons you may skip.
Two particles oscillate with the same amplitude and period. One is at its positive extreme while the other passes through the mean position. The phase difference between them is
Two SHMs have the same amplitude. The period of the first is \(2\,\text{s}\) and that of the second is \(1\,\text{s}\). The greatest speed of the second is
Two SHMs of the same frequency along one line have amplitudes \(3\,\text{cm}\) and \(4\,\text{cm}\) and a phase difference of \(\pi/2\). The amplitude of the resultant motion is
Two SHMs of the same frequency along one line, of amplitudes \(5\,\text{cm}\) and \(3\,\text{cm}\), are in opposite phase. The resultant amplitude is
A particle moves with \(x = A\sin\omega t\) and \(y = A\cos\omega t\) at the same time. Its path is
Two perpendicular SHMs have frequencies in the ratio \(1 : 2\) and start together at the mean position. The path is
The amplitude of a damped oscillator halves in \(6\,\text{s}\). Its energy halves in
A block on a spring is released from an extreme. It returns to the mean position in the least possible time without crossing it when the damping is
A block of natural frequency \(2\,\text{Hz}\) is driven by a periodic force of frequency \(5\,\text{Hz}\). In the steady state it oscillates at
The damping of a driven oscillator is reduced. Its resonance peak becomes
