In stationary waves, antinodes are the points where there is

Two waves are approaching each other with a velocity of 16 m/s and frequency n. The distance between two consecutive nodes is

Two waves are approaching each other with a velocity of 20 m / s and frequency n . The distance between two consecutive nodes is

A standing wave is represented by y = a sin (100t) cos (0.01x) , where Y and A are in millimetre, t is in seconds and x is in metre. The velocity of wave is

A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. The ratio of their length is

In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1m. When this length is changed to 0.35m the same tuning fork resonates with the first overtone. Calculate the end correction

For a gas,the rms speed at 800 k is

To what temperature should the hydrogen at room temperature (27°C) be heated at constant pressure so that the RMS velocity of its molecules becomes double of its previous value

At what temperature is the kinetic energy of a gas molecule double that of its value of 27°C

The mean kinetic energy of a gas at 300 k is 100 J. The mean energy of the gas at 450 k is equal to
