The ropes in (Figure 1) are each wrapped around a cylinder, and the two cylinders are fastened together The smaller cylinder has a diameter of 10 cm and a mass of 6.0 kg the larger cylinder has a diameter of 20 cm and a mass of 19 kg What is the angular acceleration of the cylinders? Assume that the cylinders turn on a frictionless axle.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
