which of the following statements correctly describes a transformer?

a) transformers use steady magnetic fields to induce an end in a secondary loop
b) the more could in the solenoid of the primary loop of a transformer will induce a greater emf in the secondary loop.
c) transformers are used to keep the emf constant throughout a circuit.
d) the transformer in a car engine reduces the end in the secondary coil so as not to cause a fire during start up.

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?
