In chemical formulas, the arrows represent the way of the reaction. Two opposing arrows mean that the reaction will go in both directions, until its specific equilibrum is reached.
Its your low tire pressure gauge. Check all your tires and the spare as well
the horse is your tires . " low air pressure"
I think it means parallel
Did you mean "why do the arrows point in different directions?" if so, the answer is that, since electrons are both negatively charged, the will repel from each other, causing one to go in one direction, and the other opposite that. Think "Pauli exclusion principle" which states "no two electrons in the same atom can be in the same quantum state." This 'state' includes spin, and the arrows represent the spin of the electron orbit. I hope this helped!
The two little arrows appearing on either side of a phrase or sentence in French indicate that it is being quoted or emphasized. It's similar to using quotation marks or italics in English to draw attention to that specific text.
They can only see each other facing each other(i.e. facing opposite directions).. If they are face in same directions...they will not see each other..
The arrows indicate the spin of the electron, which is either +1/2 or -1/2. This it also indicates the magnetic quantum number, or the fourth quantum number.

The brother and sister in your dream represent two different and opposite parts of yourself. You have some idea, choice or decision facing you, and you are struggling between two opposing points of view.
A number's opposite is the negitave of that number... the opposite of 2 is -2, the opposite of 947283 is -947283.
