IF YOU ANSWER THIS RIGHT I GIVE YOU BRAINLEST AND PONITS .
1.Which of the following is NOT a way to demagnetize a magnet?

1.striking the magnet hard
2.Dropping the magnet
3.heating the magnet
4.submerging the magnet in water

2.If you were to cut a magnet in half, you would get

1.two identical magnets, each with a north and south pole.
2.two pieces of metal with no magnetic properties
3.a north pole magnet, and a south pole magnet

1) 4: Submerging it in water.

2) 1: Two identical magnets, each with a north and south pole.

Explanation:

Hope this helps. I'm not too sure about #2

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
