The Richter scale rates the amount of energy released from a single earthquake, letting us know the magnitude of the disaster. A seismograph is what scientists use to actually measure the earthquake and the Richter scale is a way of putting the data into an understandable context.

Generally the equation for Satellite Speed is mathematically given by



Therefore
Period T is Given as



Answer:
Vf = 4.77 m/s
Explanation:
During the downward motion we can easily find the final velocity or the velocity with which the ball hits the ground, by using third equation of motion. The third equation of motion is given as follows:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height = 1.16 m
Vf = Final Velocity of Ball = ?
Vi = Initial Velocity of Ball = 0 m/s (Since, ball was initially at rest)
Therefore, using these values in the equation, we get:
(2)(9.8 m/s²)(1.16 m) = Vf² - (0 m/s)²
Vf = √(22.736 m²/s²)
<u>Vf = 4.77 m/s</u>
