In an early test of sound propagation through the ocean, an underwater explosion of 1 pound of dynamite in the Bahamas was detected 3200 km away on the coast of Africa. How much time elapsed between the explosion and the detection?

Respuesta :

Answer:

The time is 2133.3 sec.

Explanation:

Given that,

Distance = 3200 km

We know that,

The sound velocity in seawater is 1500 m/s.

We need to calculate the time

Using formula of velocity

[tex]v=\dfrac{d}{t}[/tex]

[tex]t=\dfrac{d}{v}[/tex]

Where, t = time

v = velocity

d = distance

Put the value into the formula

[tex]t=\dfrac{3200}{1.5}[/tex]

[tex]t=2133.3\ sec[/tex]

Hence, The time is 2133.3 sec.
