This photo shows comet hale-bopp over a desert sky. suppose you had taken another photograph from the same spot 10 minutes after this photo was taken. how would the scene have appeared at that time? a. we would see lots of smoke coming from the point where the comet crashed into the mountains. b. it would have looked virtually the same. c. we'd still see the same stars, but the comet would have moved far enough so that we'd be able to see only its tails and not its coma above the horizon. d. we'd still see the same stars, but the comet would be out of sight, having passed below the horizon. it would have looked virtually the same.

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.
