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.

As per the statement:

The formula for speed of a tidal wave is:

where

V represents the speed of a tidal wave

g represents the acceleration due to gravity i.e g = 9.8 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

then;

Simplify:

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

the 3rd option is right
