The platform starts exTwo masses $m_1$ and $m_2$ are suspended together by a massless spring of constant $K$. When the masses are inA standing wave is formed on a string by superposition of two identical waves moving in opposite directions. WA wave is represented by $y=A in(\omega t-kx)$. If the frequency is doubled while the wave speed remains unchaFor longitudinal mechanical waves in a fluid, the wave speed is given by

What does this imply?A wave is described by $y=A in(\omega t-kx)$. This wave propagates in which direction?According to the classification shown in the figure, which pair consists entirely of mechanical waves?
 = 0.05\cos(2\pi t)$ in metres. Its amplitude and period are:A spring of constant $k = 100$ N/m carries a mass of $1$ kg. Its period of oscillation is:A simple pendulum's length is increased four times. Its period changes by a factor of:A child's swing is pushed gently at its natural frequency and the amplitude grows large. This phenomenon is caA wave on a lake has wavelength $4$ m and frequency $0.5$ Hz. Its speed is:A string of mass per unit length $\mu = 0.01$ kg/m is under tension $T = 100$ N. Wave speed on it is:Two tabla drums sound at $256$ Hz and $260$ Hz simultaneously. The beat frequency heard is:An autorickshaw with horn at frequency $f_0$ moves toward a stationary listener.
