Question

DUE IN 1 MINUTE PLS ANSWER QUICK ...A sound wave moving with a speed of 1500 m/s is sent from a submarine to the ocean floor. It reflects off the
ocean floor and is received 15s later. What is the distance between the submarine and the ocean floor?

Answer 1

Answer:

s = 11250 m = 11.25 km

Explanation:

The distance covered by the sound wave while traveling from submarine to ocean floor and then back to submarine can be given as follows:

$s = vt$

but, the distance between the floor and the submarine will be half of this value:

$s = \frac{1}{2}vt$

where,

s = distance between submarine and ocean floor = ?

v = velocity of sound = 1500 m/s

t = time taken for the round trip = 15 s

Therefore,

$s = \frac{1}{2}(1500\ m/s)(15\ s)$

s = 11250 m = 11.25 km
