On august 15, 2005, a spacecraft in a 190-km, 52 °-inclination circular% parking orbit around the earth departed on a mission to mars, arriving at the red planet on% march 15, 2006, whereupon retro rockets placed it into a highly elliptic orbit with a periapsis% of 300 km and a period of 35 h. determine the total delta-v required for this mission.

For waves in the ocean, the medium of the waves is a. air b. water c. energy d. a passing boat

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.
