The echo of a gunshot is heard 5 seconds after it is fired. Calculate the distance of the surface which reflects the sound. The velocity of sound is 332m/s.

The echo of a gunshot is heard 10 seconds after it is fired. If the velocity of sound is 330 m/s, the distance of the surface which reflects the sound is

The echo of a gunshot is heard 10 seconds after it is fired. If the velocity of sound is 330 m/s, the distance of the surface which reflects the sound is

The echo of a gun shot is heard 8 sec. after the gun is fired. How far from him is the surface that reflects the sound (velocity of sound in air = 350 m/s )

(a) Explain the terms 'crests' and 'troughs' of a wave? What type of waves consist of crests and troughs? (b) The flash of a gun is seen by a man 3 seconds before the sound is heard. Calculate the distance of the gun from the man (Speed of sound in air is 332m//s ).

An echo repeats 5 syllables, each of which requires ⅕th of a second to pronounce and ½ second elapses between the time the last syllable is heard and the first syllable is echoed. Is echoed. Calculated the distance of the reflecting surface, the velocity of sound being 332 m//s .

A man fires a gun while standing between two parallel hills. If he hears the first echo after 2 s and the second echo 3 s after the first echo, then calculate the distance between the hills the velocity of sound is 330 m/s.

A man fires a gun while standing between two parallel hills. If he hears the first echo after 2 s and the second echo 3 s after the first echo, then calculate the distance between the hills the velocity of sound is 330 m/s.

The echo of a sound is heard after 5 seconds. If the speed of sound in air be 342m/s, calculate the distance of the reflecting surface.
