If a force F acting over different paths P_1 and P_2 connecting the same points

Question

If a force F acting over different paths P_1 and P_2 connecting the same points A and B performs different amounts of work on an object M for the two paths, we can conclude that? F is more like a frictional force than it is like a gravitational or spring force. Work performed by F could change the temperature of M. Both (a) and (b) are true. Neither (a) nor (b) is true. Two identical objects of mass M are in kept is uniform circular motion through strings connecting them to the center of their respective circles. The first object revolves around its center at radius R_0 and speed v-0. The second object revolves around its center at a radius 2R_s weed 2. The difference in the work performed by the strings acting on the two objects over the course of complete revelation of each is? 0 2 times 4 times .A material with very how specific would? Experience a relatively small temperature rise it absorb heat. Be similar to water in this respect. Change temperature quickly as it. We that the escape velocity required for an object to move as indefinite distance from a body of radius R_x is, where is the gravitational on the surface of the body. Given that the escape velocity from earth is 11.2 km/s, the radius is that of earth's, and gravity is 38% that of earth, what is the escape velocity from ? 2.2 km/s 4.2 km/s 5.0 km/s 5.9 km/s
