If they are both magnets, and they are the same poles facing each other (e.g. south repels south and north repels north).
They both forget about which way is North, and the needles point at each other.
Your hair has picked up extra electrons. This causes your hair to repel against each other(Like charges repel remember!). Because you hair is so tightly packed, the furthest any hair can get from another hair is to stand straight up.
Static Electricity generator an electrical force can make your hair stand on end that happens because, your hair has picked up extra electrons. This causes your hair to repel against each other(Like charges repel remember!). Because you hair is so tightly packed, the furthest any hair can get from another hair is to stand straight up.
Electrons. Mutually repel elections of other atoms when they get close (as they are then much closer to other electrons than other protons)
because when two objects are brought in contact with each other which are having different temperatures heat flow from higher to lower that is conduction takes place till the temperature of both become equal....
If they come end-to-end, they will either attract or repel depending on the polarity.If you bring the sides together, they often will slide to bring their ends + & - ends together.
EX: ++ and -- (positive positive and negative negative)

You left out "the question cannot be answered because it is nonsense". -40 and -81 WHAT? The only sense in which the question makes ... sense, is if you're talking about electrical charges; there, -40 and -81 don't make a great deal of sense, but since they're both negative two objects with these charges would repel each other.
The two like poles will repel each other, and you'll need to push them to come together. The two unlike poles will attract each other, and you'll need to hold them to keep them apart.
If i get your question right, you're asking if an iron bar can just repel another iron bar; saying the distance between them would become bigger without doing anything. The answer is no. Iron bars would only repel each other if both have been given the same polarity. In example, if you make sure both bars are positive, they will repel. If both are negatively loaded, they will repel too. If one is positive and the other negative, however, they will attract each other. Hope i got your question right, and this helps you...
I make small ufo's in copper, I just finished one , using 2 neo. magnets repelling each other, causeing one edge of the ship to hover upward, while the other end is hinged, will they repel for years or not. I don't want it coming back in the future.
By sticking or placing blocks upon each other to make an object or a building. It's just like youre building something with a plastic block like Legos, or other objects place on each other.Hope this helps.

1) they will repel each other, just like any other two positively charged objects. 2) if close enough, they will attract each other due to the strong nuclear force. Two protons, however, are not a sufficiently combination to form a nucleus -- there must be at least one (preferably two) neutrons added to allow the two protons to stay close. Why is a neutron needed to make this combination stable? We're not sure.
Yes, electron clouds have a negative charge. The electrons make up electron clouds (naturally) and the electron carries a negative electrostatic charge. Since electrons carry a negative electrostatic charge, and, by a fundamental principle of electrostatics like charges repel each other, the electrons don't like each other. That's one of the guiding principles behind electron spin and the structure of electron orbitals in chemistry and biochemistry. The big fat positive charge on the nucleus captures the electrons, but the electrons have to decide amongst themselves how they're gonna get along out in the electron shells. And they do. Is it any wonder that electron shell structures rule most of chemistry?
Let's pretend that we do not know about the law that opposite poles attract and alike poles repel. We experiment with two magnets. And we find that sometimes we can make the magnets repel, and sometimes we can make them attract. Magnets like every other Mass in the universe, are made of Atoms,, including you, and me.
