Why is there less air pressure at higher altitudes? Air at higher altitudes doesn't have as much air weighing down on it from above.

Air at higher altitudes is cooler and less turbulent.

The molecules in the air lose mass and are less effected by gravity, significantly lowering their weight

The warmer, lighter air rises bringing cooler heaver air to low altitudes.

Anybody wanna ? (picture included? )

What is the gravitational attraction between a dating couple whose centers of mass are 0.630 m apart if the boy weighs 715 n and the girl weighs 465 n?

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
