Calculate the velocity of waves having wavelength 0.1 m propagated with 1 kHz.
A sound source sends waves of 400 Hz. It produces waves of wavelength 2.5 m. The velocity of sound waves is:
A ball is dropped from the difference of height 5m. Find the velocity with which it hits the ground.
A ball is dropped from a of height of 5m from ground. Find the velocity with which it hits the ground.
