Two waves are traveling through the same container of air. wave a has a wavelength of 2.0m. wave b has a wavelength of 0.5m. the speed of wave b must be the speed of wave a.

What is the approximate vapor pressure when the gas condenses at 70 degrees celsius

What is the source of continuous heat and energy that we receive from the sun

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
