In an Isothermal process:

In a closed hall of volume 5000 m³, the total absorption of the interior surfaces is 200 metric sabin. The reverberation time is:

If the volume of a room is doubled and the total absorption is halved, the reverberation time will:

In Acoustics, 'Noise' is generally characterized by:

A source of sound of frequency 500Hz is moving towards an observer with velocity $30m/s$. The speed of sound is $330m/s$. The frequency heard by the observer will be:

A siren emitting sound of frequency \(800\,Hz\) is going away from a static listener with a speed of \(30\,m/s\). Frequency of sound heard by the listener is \((\text{velocity of sound in air}=340\,m/s)\)

The beats are produced by two sound sources of same amplitude and of nearly equal frequencies. The maximum intensity of beats will be_____when compared to that of one source is.

The displacement of a particle executing SHM is \[ x=3\sin2t+4\cos2t. \] The amplitude of particle is

The amplitude of a simple harmonic oscillator is \(A\). When the velocity of particle is half of its maximum velocity, then its position is at

If a seconds pendulum on the earth is taken to a planet whose gravity is half of the gravity on earth, its time period on that planet is
