What is the rms speed of helium atoms when the temperature of the helium gas is 206.0 k? (possibly useful constants: the atomic mass of helium is 4.00 amu, the atomic mass unit is: 1 amu = 1.66x10-27 kg, boltzmann's constant is: kg = 1.38x1023 j/k.) submit answertries 0/20 what would be the rms speed, if the temperature of the helium gas was doubled?

Astudent wears sunglasses to her read a book more easily which wave interaction occurs as light passes from the air into the plastic lenses? a polarization b.refraction c.diffraction d. interference

When using the scientist method, which step comes last?

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.
