Quizplus · Accepted Answer

The speed of a satellite in a circular orbit can be calculated using the formula v = √(GM/R), where G is the gravitational constant, M is the mass of the Earth, and R is the distance from the center of the Earth to the satellite. Given the height above Earth's surface, the correct speed is approximately 6.90 x 10^3 m/s.
