Answer and Explanation:
distance will be 2×3.14 (pie)×r
displacement will be 2r (diameter)
the motion is uniform circular motion as the object is moving in a circular path with uniform motion
They all stay the same regardless
Answer:
1. Current flows through the battery, aluminum foil, and paper clips, and into the wire coil, creating an electromagnet. One face of the coil becomes a north pole; the other a south pole. The permanent magnet attracts its opposite pole on the coil and repels its like pole, causing the coil to spin.

2. Electrical engineers say that, in an electrical circuit, electricity flows one direction: out of the positive terminal of a battery and back into the negative terminal. Electronic technicians say that electricity flows the other direction: out of the negative terminal of a battery and back into the positive terminal.

Assuming B is a stoping point that means there is acceleration because acceleration is slowing down to a stop, turning around, or speeding up. Now we also know that its speed is decreasing due to the fact that the dots are getting closser to each other. Its only velocity is it tells a direction and speed so that rules out B and C. All you have left is A and D so, you need to figure out which one has acceleration as slowing to a stop and the speed decreasing. (They kind of walk hand in hand.)
I hope that helped you.
