Temple University Depart Planets having equal masses are in

Temple University Depart Planets having equal masses are in circular orbits around a star. Planet A 4. G points) Two planet B. Which statement is\"uer has a smaller orbital radius than A) Planet A has more kinetic energy, lower potential energy, and lower energy Opotential plus kinetic) than planet B. mechanical Bo Planet A has more kinetic energy, higher potential energy, and higher energy Opotential plus kinetic) than planet B. Planet has kinetic lower potential energy, and higher mechanical more energy, energy potential plus kinetic) than planet B. D Planet and planet B have the same amount of mechanical energy (potential plus kinetic) 5. G points)A satellite circular orbit of radius R around planet x has an orbital period T lfPlanetxhad in a orbital period of this satellite in an orbit one-fourth as much mass, the of the same radius would be E) T/4 D) T12. B) 2T A) 4T 6. points A certain planet has an escape speed y from its surface. If another planet of the same size has twice the mass as the first planet, its escape speed will be D) V/2. C) A) 2K Rotational dynamics points) A uniform disk OcM (1 2MR2, hoop ocM MR2 and solid sphere (2/5 MR2 of mass M and radius R are released from rest at the same time at the top f an inclined ramp. They all roll without slipping. In what order do they reach the ottom of the ramp? disk, hoop, sphere. hoop, sphere, disk. sphere, disk, hoop. sphere, hoop, disk. hoop, disk, sphere.
