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.
To indicate that the two carbons on either side of the double bond are pointing in opposite directions (cis/trans configuration), use the terms cis for the same side and trans for opposite sides. Assign priority to groups attached to the carbons based on atomic number, and use cis for groups on the same side and trans for groups on opposite sides.
The E/Z system is used to indicate the stereochemistry around a double bond. E (entgegen) signifies "opposite" indicating the groups on each carbon are on opposite sides of the double bond. Z (zusammen) signifies "together" indicating the groups are on the same side.
When the carbons on either side of a double bond are in opposite directions, it is referred to as the E (enti) configuration. This is indicated by assigning higher priority groups to each carbon and ensuring that the highest priority groups are on opposite sides of the double bond.
use the prefix trans-
In the context of magnetic fields, parallel alignment means that the magnetic fields of two objects are pointing in the same direction, while antiparallel alignment means they are pointing in opposite directions.
Use the prefix trans
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.
use the prefix TRANS-
To indicate that the two carbons on either side of the double bond are pointing in opposite directions (cis/trans configuration), use the terms cis for the same side and trans for opposite sides. Assign priority to groups attached to the carbons based on atomic number, and use cis for groups on the same side and trans for groups on opposite sides.
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!
This would indicate negative acceleration, which would mean that the object in question is speeding up.
You click the opposite of whatever "e" he is pointing to. If the "e" is pointing to the left, choose the one that is pointing right.

A pointing finger is generally used to indicate attention or direction. For example, pointing fingers may be seen in businesses to indicate things like where the restrooms are. The more common 'arrow' style of graphic is used in the same way.
The E/Z system is used to indicate the stereochemistry around a double bond. E (entgegen) signifies "opposite" indicating the groups on each carbon are on opposite sides of the double bond. Z (zusammen) signifies "together" indicating the groups are on the same side.
electrons in magnets are organized and generally pointing in the same direction
V-shaped contour lines pointing uphill indicate a steep slope or ridge. The closer the contour lines are together, the steeper the slope.
