If you leave the door of your refrigerator open while it is operating it Blocks I and II, each with a mass of 1.0kg, are hung from the celling of an elevator by ropes 1 and 2. What is the force exerted by rope 1 on block II when the elevator Is accelerating downward at lm/s2? (Take g=10m/s2.) In a given reversible process, the temperature of an ideal gas is kept constant while the gas is compressed to a smaller volume. Select the true statement: In the figure above, M1>M2, and both are sitting on a frictlonless table. We can apply a horizontal force F from either the right or the left to move the two blocks. The magnitude of the force between masses M1 and M2 is
