The statement “force equals mass times acceleration” is newton’s second law of motion. why is this a law rather than a theory?
(a) it states, rather than explains, the relationship between the variables.
(b) it cannot be proven, whereas a theory can be proven.
(c) it may be revised if new information shows that the relationship has changed.
(d) it was classified as a law because it is related to other similar discoveries.

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?
