A 500 kg satellite experiences a gravitational force of 3000 N, while moving in a circular orbit around the earth a) Determine the radius of the circular orbit. b) Determine the speed of the satellite. c) Determine the period of the orbit.

Anuclear power plant generates 3000 mw of heat energy from nuclear reactions in the reactor's core. this energy is used to boil water and produce high-pressure steam at 290 ∘c. the steam spins a turbine, which produces 1000 mw of electric power, then the steam is condensed and the water is cooled to 25∘c before starting the cycle again.
