The upward and downward movement of air in the atmosphere creates pressure systems. arrange the steps in the correct order to describe how a high-pressure system forms and leads to pleasant weather. the skies clear, making way for pleasant weather. cool, dense air begins to sink downward. pressure differences cause wind to blow outward. a high-pressure system forms.

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?
