The displacement of a particle is given by, $x={\cos }^2\omega t$. The motion is,

If the length of a simple pendulum is increased by $4$-fold, the time period of oscillation will be,

Bats can know about their prey at a distance even in the night by emitting,

Motion of a particle can be described in $x$-direction by, $x=a \sin \omega t$ and $y$-direction by, $y=b \cos \omega t$. The particle is moving in,

The displacement $\left(x\right)$-time $\left(t\right)$ graph given above approximately represents the motion of a,

Sound waves are similar to the waves,

Ultrasonic waves of frequency $3\times {10}^5 \mathrm{Hz}$ are passed through a medium where the speed of sound is $10$ times that in air (speed of sound in air is $300 \mathrm{m} {\mathrm{s}}^{-1}$). The wavelength of this wave in that medium will be of the order of,

The loudness of sound is related to _____.
