Achild pulls a block across the floor with force applied by a horizontally held string. a smaller frictional force also acts upon the block yielding a net force on the block that is smaller than the force applied by the string. how does the work done by the string compare with the change in the block’s kinetic energy?

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.
