The diagram shows an electric motor. An illustration of a coil of wire connected to a battery labeled Z. The coil is in between 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

so easy. just google the electromagnetic waves and it’ll pop up.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

the answer is 100. i just did this lesson and got a 100% on it. : )
