Question

Rob is studying for an exam. He listed some properties of magnets in a Maglev train.

Which best explains Rob’s error?

Answer 1

D. The repelling of the support magnet decreases friction.

The magnets are repelling, so they are not directly touching. This allows for decreased friction.

Answer 2

Rob's error was not letting us see his list so that we can't help him evaluate the properties he listed.
