Answer :
Final answer:
The answer explains how to calculate the orbital speed and period of revolution of an artificial satellite orbiting the Earth at a specific height, along with information on Clarke's orbit.
Explanation:
Orbital speed: To calculate the orbital speed of a satellite, we use 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. Substituting the values and solving will give you the orbital speed.
Period of revolution: The period of revolution can be calculated using Kepler's third law, which states that T² = (4π²r³) / GM. By substituting the values for r and solving, you can find the period of revolution.
Clarke's orbit: This orbit is named after the author who suggested it, and satellites in this orbit always stay above a specific position on Earth's surface.
