Looking at the diagram above, in which part of the orbit is the planet moving the fastest? a. A d. D b. B e. none of the above 0. C Looking at the diagram below, in which part of the orbit does the planet have zero kinetic energy? a. A d. D b. B e. none of the above 0. C Looking at the diagram above, in which part of the orbit does the planet have minimum kinetic energy? a. A d. D b. B e. none of the above 0. C Looking at the diagram below, which part of the orbit corresponds to the perihelion? a. A d. D b. B e. none of the above c.C The binding energy of a 257kg satellite in orbit at an altitude of 5.9 X 106 m above Earth's surface (rt = 6.38 X 106 111, ME = 5.98 X 1024 kg) is a. 4.2 X 109 J (1. 2.7 X 1010] b. 1.2 X1010J e. 5.4 X 1010] c. 1.6 x 1010 J If the period of orbit for a satellite increases by a factor of 2, the average radius of orbit will increase by a factor of a. 0.50 d. 1.6 b. 0.63 e. 2.0 C. 1.0Two 2.0-kg spheres each carry a charge of 2.0 C. How does FE compare with F? a. FE = Fg b. Fg > FE c. FE > Fg d. If the charges on the spheres are the same, then F. > FE, but if the charges are opposite then FE > Fg. e. FE and Fo cannot be compared without knowing the distance between the spheres
