650 m [N37ºW], then 520 m [E], then 330 m [S30.0ºW]. He didn't find it! So he returned empty handed. He took the shortest path to go back where he started. If it took him 1.0 hour to get back, what was his average velocity for the return trip only (in m/s)?

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.
