calculate the redshift gh/c^2 if h is the distance from the ground to a satellite in low-Earth orbit, 300km. Suppose the "light" is actually a radio wave with a frequency of 10^11 Hz. How many cycles would the transmitter emit if it ran for one day? How many fewer would be received in one day by the satellite? How long did it take the transmitter to generate these "extra" cycles?

9.8 m/s^2*300000m/(9*10^16) m^2/s^2 = 3.27*10^-11.

The red-shifted frequency will be that times 10^11 Hz, or 3.27Hz. I don't know how to use this to find the answers to the questions being asked.

    You observe an arti cial satellite orbiting the earth and estimate it is at an altitude h = [03] km above the earth's surface and has a mass m = 3500 kg. You wish to calculate when the satellite will be back in the same position.
