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 Eart

fredd [130]

Answer:

70 m/s

Step-by-step explanation:

"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":

The sentence above can be interpreted into the equation shown below (letting speed of tidal wave be "s", acceleration due to gravity be "g", and depth be "d"):

$s=\sqrt{g*d}$

Given d = 500 and g = 9.8, we find speed (s):

$s=\sqrt{g*d} \\s=\sqrt{(9.8)*(500)} \\s=\sqrt{4900}\\ s=70$

Hence, the speed is 70 meters per second.
