A sonar echo returns to a submarine 2.30 s after being emitted. The distance to the object creating the echo is 1702m
Let's understand the solution in detail,
The speed of sound in water is equal to 1480m/s
The time the waves take to hit the object and return back to the receiver is 2.30s
As we already know distance = speed x time
So the distance of the object = (speed x time)/2
We are dividing the distance by two because sound travels the same distance while reaching the object from the emitter and reaching back to the receiver after getting reflected by the object.
Therefore the distance comes out as [tex]\frac{1480 x 2.30}{2}[/tex]
which is equal to 1702 meters
