Which description correctly summarizes how an electric motor causes an axle to turn?
O Force generated through the brushes rotates the commutators. They then generate a force that rotates the
armature to spin until the like poles of the electromagnet and the permanent magnet align and motion stops.
O The poles of the magnetic field generated around the armature are attracted to the opposite poles of the
permanent magnet. As the opposite poles align, the commutator reverses the current direction so like poles are
aligned and the armature continues to spin.
O The poles of the magnetic field generated around the armature are attracted to the like poles of the permanent
magnet. This causes the armature to spin and the electricity within the armature to flow back through the circuit
to the battery

Which sentences describe point source pollution? in this type of pollution, the source of the pollution is single and easily identifiable. when runoff water from the melting of snow mixes with debris, it creates pollution. the runoff water, mixed with pollutants, reaches large areas with disastrous effects. alternatively, when a wastewater treatment plant releases harmful chemicals into a stream, the chemicals pollute the stream water because they are not treated for safety.
