Answer:
As per the statement:
The formula for speed of a tidal wave is: [tex]v = \sqrt{g \cdot h}[/tex]
where
V represents the speed of a tidal wave
g represents the acceleration due to gravity i.e g = 9.8 [tex]m/s^2[/tex] 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 [tex]m/s^2[/tex]
then;
[tex]v = \sqrt{9.8 \cdot 500}[/tex]
[tex]v = \sqrt{4900}[/tex]
Simplify:
[tex]v = 70 m/s[/tex]
therefore, the speed of a tidal wave will be 70 m/s
