Question

A body sitting in a boat fires a gun. An observer P is at a distance of 50 from the
boat. Another observer Q is a diver, who is 50 m under water. Both hear the
sound of gun
1) P hear the sound first
2) Q hear the sound first
3) Both P and Q hear the sound at the same time
4) none of the above​

Answer 1

Answer:

Q hears the sound first because the velocity of sound in water is 1480m/s and velocity of sound in air is approx 340m/s so q hears sound in approx 0.06 s and p in 0.3s so clearly Q hears sound first

Answer 2

Answer:2)Q hear the sound first

Explanation: Q is 50 m below in the water while P is 50 m in the air so speed of sound is more in the water as compare to air
