प्रश्न
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 332 m/s).
उत्तर
We have to find the distance to which the sound will reach in a given time.
Given: Velocity of sound ν = 332 m/s
Time t = 3 s
So,
Distance = Speed × Time
Therefore, distance covered is
= 332 × 3 m
= 996 m
