Hi,
I am looking for satellites and their coverage maps which cover satellite tv transmission for North America.
Thank you.

13 orbits per day. Determine the height of the satellite’s orbit above the surface of the Earth. Determine the speed of the satellite in that orbit.

please help and explain step by step thank you so much

Find the speed of a satellite in a circular orbit around the earth with a radius 3.35 times the mean radius of the earth; Radius of earth= 6.37·103 km; Mass of earth= 5.98·1024 kg.

A satellite moves in a circular orbit around the Earth at a speed of 6.1 km/s.
Determine the satellite’s altitude above the surface of the earth. Assume the earth is a homogeneous sphere of radius 6370 km and mass 5.98E24 kg. The value of the universal gravitational constant is 6.67259E-11.
Answer in units of km.

Given: G = 6.67259 × 10−11 Nm2/kg2
Calculate the work required to move a planet’s satellite of mass 2330 kg from a circular orbit of radius 2R to one of radius 3R, where 8.98×106 m is the radius of the planet. The mass of the planet is 4.91 × 1024 kg.
Answer in units of J.
