Which of the following statements are true? a. Earth's geographic south pole is also a magnetic south pole. b. Scientists have evidence that single isolated magnetic poles, called magnetic monopoles, exist. c. The north pole of a bar magnet will attract the south pole of another bar magnet. d. The south poles of two bar magnets will repel each other. e. The north poles of two bar magnets will attract each other. f. Earth's geographic north pole is actually a magnetic south pole.

c. The north pole of a bar magnet will attract the south pole of another bar magnet.

d. The south poles of two bar magnets will repel each other.

e. The north poles of two bar magnets will attract each other. f. Earth's geographic north pole is actually a magnetic south pole.

Explanation:

Law of magnetism states that like poles repel and unlike poles attract. This means north and south poles attract and north and north or south and south poles repel each other.

The Earth's magnetic North Pole attracts the north pole of other magnets, it is technically the South Pole of the planet's magnetic field.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
