The diagram shows an electric motor. An illustration of a coil of wire connected to a battery labeled Z. The coil is inbetween a north pole and a south pole. The coil is rotating clockwise. The point where the positive electrode of the battery is connected to it is labeled Y. The long straight with that it rotates around is labeled W. The ring with a slit that the battery is connected to is labeled X. Which part of the motor is responsible for reversing the flow of current? W X Y Z

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
