According to the law of universal gravitation, any two objects are attracted to each other. the strength of the gravitational force depends on the masses of the objects and their distance from each other.
many stars have planets around them. if there were no gravity attracting a planet to its star, the planet's motion would carry it away from the star. however, when this motion is balanced by the gravitational attraction to the star, the planet orbits the star.
two solar systems each have a planet the same distance from the star. the planets have the same mass, but planet a orbits a more massive star than planet b.

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.
