Which Article of the Indian Constitution deals with the impeachment of the President?

Two particles $\mathrm{A},\mathrm{ }\mathrm{B}$ are moving on two concentric circles of radii $R_1$ and $R_2$ with equal angular speed $\omega .$ At $t=0,$ their positions and direction of motion are shown in the figure:

The relative velocity $\overrightarrow{V_A}-\overrightarrow{V_B}$ at $t=\frac{\pi }{2\omega }$ is given by:

If the kinetic energy of a particle of mass $m,$ performing uniform circular motion in a circle of radius $r,$ is $E,$ find the acceleration of the particle.

Calculate the increase in velocity of sound produced by $1^o \mathrm{C}$ rises in temp. If the velocity of sound at $0^{\mathrm{o}} \mathrm{C}$ is $332 {\mathrm{ms}}^{-1}$?

A wire stretched between two rigid supports vibrates in its fundamental mode with a frequency of $45 \mathrm{Hz}$. The mass of the wire is $3.5\times {10}^{-2}kg$ and its linear mass density is $4.0\times {10}^{-2}kg{m}^{-1}$. What is the speed of a transverse wave on the string

A steel wire has a length of $12.0 \mathrm{m}$ and a mass of $2.10 \mathrm{kg}$. What should be the tension in the wire so that speed of a transverse wave on the wire equals the speed of sound in dry air at ${20}^{\mathrm{o}}\mathrm{C}=343 {\mathrm{ms}}^{-1}.$

The speed of a wave in a medium is $760 \mathrm{m} {\mathrm{s}}^{-1}$. If $3600$ waves are passing through a point in the medium in $2$ minutes, then is wavelength is

A string of mass $2.50 \mathrm{kg}$ is under a tension of $200 \mathrm{N}$. The length of the stretched string is $20.0 \mathrm{m}$. If the transverse jerk is struck at one end of the string, how long does the disturbance take to reach the other end?

Velocity of sound in air is
