Newton's First and Second Laws of Motion:Question 3Kepler-10b, the first confirmed terrestrial extrasolar planet, is about 564 light-years away from Earth. Kepler-10b is a superearth, meaning it is a little larger and more massive than Earth. It has a surface gravity that is 1.53 times that of Earth. How much thrust would be required to accelerate a 5,000-kg spacecraft 2.13 m/s2 from the surface of Kepler-10b

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.
