two systems contain vastly different amounts of internal energy. For the sake of definiteness, assume that system A contains 1000000 J of internal energy and system B contains 100 J of internal energy. In which direction will heat flow if these two systems are placed in thermal contact?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
