Answer:
r = 4.24x10⁴ km.
Explanation:
To find the radius of such an orbit we need to use Kepler's third law:
<em>where T₁: is the orbital period of the geosynchronous Earth satellite = 1 d, T₂: is the orbital period of the moon = 0.07481 y, r₁: is the radius of such an orbit and r₂: is the orbital radius of the moon = 3.84x10⁵ km. </em>
From equation (1), r₁ is:
Therefore, the radius of such an orbit is 4.24x10⁴ km.

Frequency, is the number of times in a cycle
Answer: The potential energy of the cars at its maximum at the start and the end of the trip. Potential energy approaches zero when the cars are near the ground at the lowest point on the tracks. The kinetic energy of the cars is zero at the start and the end of the trip because cars aren’t moving. Kinetic energy is at its maximum when the cars are the lowest point on the track after racing down the hill. Yw:)
