Choose all the answers that apply. according to newton's first law of motion: objects at rest will remain at rest unless acted upon by an outside force an increase in mass will cause an increase in inertia the greater the magnitude of force, the faster the acceleration objects in motion will remain in motion unless acted upon by an outside force every action has an equal and opposite reaction there can be more than one

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
