Answer 16

Joe follows the procedure below to make a compass.

1. Move a magnet from the top of a needle to its point fifty times.
2. Lay the needle on a cork that is floating in a bowl of water.
3. Observe the direction that the needle points.

What is the purpose of step 1?

to give the needle an electric charge
to make the needle sharper
to magnetize the needle
to flatten the side of the needle

Which shows the pieces after the magnet is cut?

Answer 23

a

Answer 24

theres more attachments omg give me another minute

Answer 25

So far right now, A is the correct answer

Answer 31

Laticia draws the diagram below to show Earth’s magnetic field.



What error did Laticia make?

The dashed line should be drawn in the same place as the solid line.
The solid line should be drawn in the same place as the dashed line.
The arrows to the left of Earth should point down.
The arrows to the right of Earth should point up.

Answer 32

i think its A

D

Answer 34

Please select the word from the list that best fits the definition

Equal to current multiplied by electric potential difference

current
open circuit
closed circuit
power
energy
ohm's law

Answer 35

pick one

Answer 36

I am going with Ohm's law

Answer 37

How are the electric field lines around a positive charge affected when a second positive charge is near it?

The field lines combine with the lines around the second positive charge.
The field lines overlap with the lines from the second positive charge.
The field lines bend toward the second positive charge.
The field lines bend away from the second positive charge.

Answer 38

D

Answer 39

Based on illustrations of magnetic field lines, where could an object be placed so it would not experience a magnetic force?

halfway between the like poles of two magnets, because the field lines bend away and do not enter this area
halfway between the opposite poles of two magnets, because the field lines are the closest together
above the middle of a bar magnet, because the magnetic field lines are only found around the sides of the magnet
above a pole of a bar magnet, because the magnetic field lines either go in or go out at the end

Answer 47

The north pole of a bar magnet is moved close to the north pole of a second bar magnet. What prediction best describes how the first magnet responds when it is released?

It will move toward the second magnet because like poles repel.
It will move toward the second magnet because like poles attract.
It will move away from the second magnet because like poles repel.
It will move away from the second magnet because like poles attract.

Answer 51

Oran uses a ball, a bar magnet, and a compass to create a model of Earth’s magnetic field. How could he best use these materials?

He could glue the compass to the ball so the needle points to the top of the ball, and move the bar magnet to show how the compass direction changes.
He could glue the compass to the ball so the needle points to the bottom of the ball, and move the bar magnet to show how the compass direction changes.
He could place the bar magnet in the ball so that the north pole of the magnet is at the top of the ball and the compass needle points to it.
He could place the bar magnet in the ball so that the south pole of the magnet is at the top of the ball and the compass needle points to it.
