A flat circular coil 16 turns, each of diameter 20 cm, is in a uniform and steady 0.13-T magnetic field. a) Find the total magnetic flux through the coil when the field is perpendicular to the plane of the coil. A) 0.13 T middot m^2 B) 0.032 T middot m^2 C) 0.00032 T middot m^2 D) 0.065 T middot m^2 E) 0.00065 T middot m^2 If the coil is rotated in 10 ms so its plane is parallel to the field, find the average induced e in the coil. A) 6500 V B) 6.5 V C) 13000 V D) 13 V E) 3.2 V

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal. find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
