Nolan set up the equipment shown in order to induce a current in a wire. A horizontal coil of wire on a spool is connected to 2 terminals of a meter with a needle, which can go from plus to minus. A hand holds a bar magnet oriented horizontally near the right end of the spool with the S pole toward the spool and the N pole toward the hand. Which best explains why no current is induced? The wire needs to be coiled less tightly. The wire needs to be straight, not coiled. The magnet needs to be moved through the coils of wire. The magnet needs to be held above the coils of wire.

The answer is C on edge

Step-by-step explanation:

Took the test.

The magnet needs to be moved through the coils of wire is correct

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
