what must be the orbital speed of a satellite in a circular orbit 820 km Above the surface of the earth
Added by Sarah H.
Step 1
First, we need to find the radius of the orbit. The radius of the Earth is approximately 6371 km. So, the radius of the orbit is 6371 km (radius of the Earth) + 820 km (height above the Earth) = 7191 km. Show more…
