Asatellite of mass 190 kg is placed into earth orbit at a height of 850 km above the surface.
(a) assuming a circular orbit, how long does the satellite take to complete one orbit?
(b) what is the satellite's speed?
(c) starting from the satellite on the earth's surface, what is the minimum energy input necessary to place this satellite in orbit? ignore air resistance but include the effect of the planet's daily rotation.

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
