Drawbridges, such as this one at the tower of london, are raised and lowered by cable systems. now consider the drawbridge illustrated below wherein the nearly horizontal brown door is centered along the vertical brick wall, the door-wall angle is α = 80 o as measured relative to the black hinge axis, the tension (magnitude) in each cable is t = 600 n and the relevant dimensions are a = 330 cm, b = 110 cm, c = 600 cm and d = 390 cm. determine the resultant torque (magnitude) | ( m r ) a x i s | in nm that the two cables contribute to the moment about the hinge axis. | ( m r ) a x i s | = nm

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

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?
