40. A block with a mass of 6.0 kg is held in equilibrium on an incline of angle 0 = 30.0° by a
horizontal force, F, as shown in the figure. Find the magnitudes of the normal force on the block and of E. (Ignore friction.)

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
