A300g marble is travelling at a speed of 3.00 m/s horizontally along a tabletop that is 1.00 m above the floor. the marble rolls up a ramp that launches it into the air. at the highest point in its flight the marble has a horizontal velocity of 1.10 m/s. if friction is negligible, how high above the floor is the marble at its highest point?

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?
