Beverage can is thrown upward and then falls back down to the floor. as usual, a y axis extends upward (positive direction). which of the following best describes the acceleration of the can during its free flight? a) -9.8 m/s^2, then momentarily zero, then +9.8 m/s^2b) +9.8 m/s^2 throughoutc) -9.8 m/s^2 throughoutd) zero throughoute) +9.8 m/s^2, then momentarily zero, then -9.8 m/s^2

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.
