Acompass needle normally points toward earth’s magnetic pole, which is near the north pole. which best explains why the needle moves away from the pole when it comes close to a current-carrying wire?
-current within the wire weakens the magnetic force of the pole.
-magnetism surrounding the wire weakens the magnetic force of the pole.
-magnetism surrounding the wire draws the needle toward the wire.

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
