NEET UG 2002 — Waves & Oscillations

A wave travelling in the positive $x$-direction with amplitude $\mathrm{A}=0.2 \mathrm{~m}$, velocity $v=360 \mathrm{~ms}^{-1}$ and wavelength $\lambda$ $=60 \mathrm{~m}$, then the correct expression for the wave is:

Displacement between the maximum potential energy (P.E.) position and the maximum energy (K.E.) position for a particle executing simple harmonic motion is:

When a oscillator completes 100 oscillations its amplitude reduces to $\frac{1}{3}$ of the initial value. What will be its amplitude when it completes 200 oscillations?

A mass is suspended separately by two different springs in successive order, then the time period is $T_1$ and $T_2$, respectively. If it is connected by both spring as shown in figure, then the time period $T_0$, so the correct reaction is:
