For a satellite in an *elliptical* orbit around the earth, the amount of work done in a short time interval by the gravitational force from the earth on the satellite A) is zero B) is positive when the satellite is getting closer to the earth, and negative when it's getting farther from the earth C) is negative when the satellite is getting closer to the earth, and positive when it's getting farther from the earth D) is positive. E) is negative. Hint: Draw a diagram and then use either the work formula or the mechanical energy–the kinetic and gravitational poter nergies–to justify your answer.)
