Question

A group of students sets up an electric circuit with wires, a battery, and a light bulb. Why is their circuit called a direct circuit?(1 point)

Responses
The light bulb is directly connected to the battery.
The light bulb is directly connected to the battery.
The circuit is complete, so electrons can flow freely.
The circuit is complete, so electrons can flow freely.
The electrons flow back and forth through the circuit.
The electrons flow back and forth through the circuit.
The flow of electrons travels in one direction.

Answer 1

The light bulb is directly connected to the battery.

Answer 2

In 1–2 sentences, explain how electromagnets move a maglev train.(2 points)

Answer 3

Electromagnets in the track repel the magnets on the bottom of the train, creating a magnetic levitation effect that allows the train to float and move forward. This eliminates friction and allows for faster, smoother, and more efficient travel.
