An observer at a distance of 800 m from a sound source heard first the sound signal which travelled through water and 1.785 later the signal which travelled through air. The velocity of sound in water is (x.y) × 10 3 m/s. Where x and y is the single digit non zero number, find x. The air temperature is 17ºC –
Text Solution

CHECK THE SOLUTION
(1)
We are told:
Distance between source and observer: 
Time difference of arrival: 
Air temperature 
Velocity of sound in air:
Time taken through air
Time taken through water
Velocity in water
Express in given form
So,
