Question

12 The deepest part of the oceans in the world is the Mariana Trench in the Pacific Conan It is 11, 000 m deep How long will it take for sound transmitted by a ship to the surface of water above the trench to be selected? (Speed of sound in senator -1500 mis)

Answer 1

Step-by-step explanation:

Time taken by sound to come back to surface after reflection from trench

= distance travelled / speed of sound

= 2 x 11000 / 1500

= 14.66 s

In one way , sound will take half the time = 7.33 s .
