In kinetic theory of gases, atoms are modeled as point masses mwith mean speedvrelated to temperaturetbym v2 = 3 kt, where k is boltzmann’s constant. assuming gas atoms travel severalthousand angstroms between collisions with each other, how cool would hydrogen gas need to be before quantum mechanics would have to be taken into consideration

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?
