Two pulleys with different radii are attached to each other so that they rotate together about a horizontal axis through their common center. There is negligible friction in the axel. Object 1 hangs from a light string wrapped around the larger pulley, while object 2 hands from another light string wrapped around the smaller pulley, as shown in the figure above.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
