Hi there!
The period of an orbit can be found by:

T = Period (? s)
r = radius of orbit (6400000 m)
v = speed of the satellite (8000 m/s)
This is the same as the distance = vt equation. The total distance traveled by the satellite is the circumference of its circular orbit.
Let's plug in what we know and solve.

Answer:
So do 2400 divided by 70. I got 34.285714 and the numbers behind the decimal are repeating. If you round it you get 34.3
When potential energy <u>decreases</u>, kinetic energy increases.
There is a a thing. so you use the scientific method by
The observation, measuring, and the experiment. also the formulation and then testing of your hypothesis
