Sound travels much faster in water than air. it takes 4.2 seconds for the sound of an explosion to travel underwater to a diver 6,006 m away. what is the speed of sound in water? include correct units with your answer.

1430 m/s

Explanation:

In this problem, the speed of sound in water is given by:

where

d is the distance travelled by the sound in water

t is the time taken

In this problem, we have:

d = 6,006 m

t = 4.2 s

So, the speed of sound in water is

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

frequency or wavelenth of em radiation in a vacuum
