A freeway exit ramp has a single 3.6 m lane and consists entirely of a horizontal curve with a central angle of 90 degrees and length of 200 m. If the distance cleared of obstacles is 6.95 m from the centerline, what design speed was used

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?

Can anybody me with this? ? (picture included.)

If forces acting on an object are unbalanced. true or false
