A spray gun, used to apply paint, contains two tubes inside of it: one tube comes up from the supply of paint and one supplies a flow of compressed air that blows across the top of the paint tube. This rush of air creates , which sucks the paint up the tube and into the stream of air.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

Why do electrons further from the nucleus have more energy
