Compressed air is used to fire a 50 gram ball vertically from a 1-meter tube. the air exerts an upward force of 2 n on the ball as long as it in the tube. how high does the ball go above the top of the tube?

From the graph the speed of the snail in the first 20 seconds centimeter/second. after that, the snail remains in the same place for seconds

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?
