Ultrasonic, infrasonic and audio waves travel through a medium with speeds $V _{u}, V _{i}$ and $V _a$ respectively then,
The extension in a string obeying Hooke's law $v$ is $x$. The speed of sound in the stretched string is $v$. If the extension in the string is increased to $1.5\ x$, the speed of sound will be
According to Newton's formula, the speed of sound in air at STP is:
(Take the mass of $1$ mole of are is $29 \times 10^{-3} \,\,kg)$
The velocities of sound at the same temperature in two monoatomic gases of densities $p _1$ and $p _2$ are $v _1$ and $v _2$ respectively. If $p _1/p _2 = 4$, then the value of $v _1/v _2$ is
The speed of sound through a gaseous medium bears a constant ratio with the rms speed of its molecules. What is this constant ratio ?
If the pressure of a fixed quantity of a gas is increased 4 times keeping the temperature constant, the r.m.s velocity will :
If $C _{s}$ be the velocity of sound in air and $C$ be the rms velocity, then
With increase in temperature, the rms speed and wave speed in a gas
If nitrogen gas molecule goes straight up with its rms speed at $0^o$C from the surface of the earth and there are no collisions with other molecules, then it will rise to an approximate height of:
RMS speed of sound varies with change in composition of the medium (diatomic, monoatomic, etc), in which the wave travels
