PLEASE ANSWER dont answer if you dont know Think about what forces are involved in the different parts of this investigation. Explain why there is a difference in the amount of Newtons measured when you weighed the objects versus when you pulled the objects across a surface. Your answer should mention how the force=mass*acceleration formula is involved.

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.
