(a) You ride your bike along a straight road for a distance d at a constant speed of 15.0 mi/hr and then for another distance 2d along the same straight road at a different constant speed. The average speed for the total trip is 14.0 mi/hr. Determine your constant speed during the second part of the trip. (Enter your answer to at least two decimal places.)

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?
