So I know this is a weird question but if you were to send a piece of paper from the Milky Way to the andromeda galaxy how long would it take (please don’t answer with I don’t know people keep doing that)

The text compares alternating current with direct current. how are they different? a alternating current reverses direction in the electrical wiring. direct current flows in one direction only. b direct current reverses direction in the electrical wiring. alternating current flows in one direction only. c direct current is powered by solar energy. alternating current is powered by electrical energy. d alternating current does not move in the electrical wiring. direct current does move in the electrical wiring.
