It can go in either direction i think Thomassen
Two arrows pointing in opposite directions usually symbolize balance or opposition. It can indicate a state of equilibrium or a binary relationship where two forces are working in opposition.
A yellow sign with two arrows pointing in opposite directions means there is a divided highway ahead.
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.
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!
Two arrows pointing at each other is a common symbol representing a two-way relationship or interaction, often indicating give and take, balance, or mutual influence between two elements.
I think the "Fallout Shelter" sign
the arrows mean "is eaten by" so for example, if there is a picture of a rabbit with a arrow pointing to a fox it would mean that the rabbit "is eaten by" the fox
Tire Pressure
It means traffic can pass on either side of an obstruction such as an island.
It means you stand with your feet pointing in opposite directions, legs open from the hip-socket.
the arrows in a food chain mean "is eaten by" for example: grass----->rabbit----->fox the grass is eaten by or consumed by the rabbit. the rabbit is then consumed or eaten by the fox hope this helps
the horse is your tires . " low air pressure"
