Two satellites are in circular orbits around the earth. The orbit for satellite A is at a height of 511 km above the earth's surface, while that for satellite B is at a height of 739 km. Find the orbital speed for satellite A and satellite B.

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
