Question

The speed of a tidal wave in meters/second is given by the square root of the product of the acceleration due to gravity on Earth (9.8 meters/second2) and the depth of the ocean in meters.
If the ocean is 500 meters deep, the speed of the tidal wave will be__
m/s.

Answer 1

Answer:

As per the statement:

The formula for speed of a tidal wave is: $v = \sqrt{g \cdot h}$

where

V represents the speed of a tidal wave

g represents the acceleration due to gravity i.e g = 9.8 $m/s^2$ and

h represents the depth of the ocean in meters.

It is also given that If the ocean is 500 meters deep.

we have to find the speed of the tidal wave:

h = 500 meter , g = 9.8 $m/s^2$

then;

$v = \sqrt{9.8 \cdot 500}$

$v = \sqrt{4900}$

Simplify:

$v = 70 m/s$

therefore, the speed of a tidal wave will be 70 m/s
