Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 280 w/m2. 1) if the polarization angle between the filters increases by 25∘ from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized. (express your answer to two significant figures.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
