Unpolarized light with an intensity of 42 units is incident on a set of two successive polarizing filters. The polarization axis of the first filter is aligned horizontally, while the axis of the second filter is rotated 32 from the vertical. Determine the intensity of the light after passing through the two filters

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

the doppler effect is used by weather forecasters to measure 

moving clouds

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
