You are on an unknown planet with an unknown acceleration due to gravity. In order to measure the acceleration due to gravity, you decide to drop the Keyes to your spaceship from a height of 3.25m, if it took 5.05s for them to hit the surface of the planet, what is the acceleration due to gravity

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.
