The highest-caliber cannon ever built (though never used) is located in moscow russia. the diameter of the cannon’s bar is about 82 cm, and the cannon’s mass is 35027 kg. suppose the cannon were lifted by airplane. if the potential energy associated with this cannon were 8.88 x 10^8 j, what would be it’s height above sea level?

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.
