Which is an aspect of the kinetic-molecular theory and can be used to explain the behavior of plasmas? Particle spacing can allow a very high density.
Particle kinetic energy is independent of temperature.
Particles vibrate quickly in stationary positions.
Particles exchange energy through elastic collisions

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

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?
