Unpolarized light travels through 2 linear polarizers. what (minimum) angle should the second polarizer be relative to the first polarizer (the difference between q1 and q2) so that the final intensity of light is 1/3 the original value?

Once cells with nuclei developed, organisms were able to become more complex, which allowed them to adapt to the conditions in more habitats. by which process do organisms adapt and evolve?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
