The polarity arrow should point from sulfur (S) to phosphorus (P) in P - S bond as sulfur is more electronegative than phosphorus. In the case of P - O bond, the arrow should point from oxygen (O) to phosphorus (P) as oxygen is also more electronegative than phosphorus.
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.
Without seeing the diagram, it's difficult to provide a specific answer, but generally, the arrows in a diagram of an amoeba could indicate processes such as ingestion, digestion, or excretion. Amoebas use pseudopodia to engulf food particles in a process called phagocytosis, which is part of their feeding mechanism. If the arrows point towards a specific structure, it may represent the direction of food intake or waste elimination.
Boiling point is not directly related to the polarity of water. The boiling point of water is determined by the strength of intermolecular forces between water molecules. Water is a polar molecule due to its asymmetrical shape and unequal sharing of electrons, which leads to hydrogen bonding and a relatively high boiling point.
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!
To maintain equilibrium, the clockwise moment created by the 10N force must be balanced by an equal anticlockwise moment. Therefore, you should apply the 20N force at a distance of 5m on the opposite side of the pivot point in the horizontal direction. This will create an equal and opposite moment, maintaining equilibrium.
The polarity arrows should point towards the more electronegative atom, which is the oxygen atom. The oxygen atom attracts the shared electron pairs more strongly than the carbon atom, creating a partial negative charge on the oxygens and a partial positive charge on the carbon atom.
Arrows point in the direction of airflow.
The arrows in the diagram point to the right.
No, when velocity decreases and acceleration arrows point in the same direction, it means the object is speeding up in the negative direction.
The arrow represents direction and leading. When lost an arrow will point you in the right direction. The recycle sign are arrows formed to make a triangle.
Electric field lines are drawn with arrows to show the direction of the force that a positive test charge would experience if placed in the field. The direction of the electric field at any point is the direction that a positive test charge would move when placed in the field at that point.
no because the arrows in a food web/chain mean 'is eaten by' because a worm is eaten by a pidgeon.
The arrow represents direction and leading. When lost an arrow will point you in the right direction. The recycle sign are arrows formed to make a triangle.
An example of a picture showing movement with arrows could be a diagram illustrating the path of a ball being kicked from point A to point B in a soccer game. Arrows could be used to indicate the direction and speed of the ball's movement.

To use the right-hand rule for determining the polarity of an electromagnet, hold your right hand with your thumb pointing in the direction of the current flow. Your fingers should curl in the direction of the magnetic field. The side of the electromagnet where your fingers point is the north pole, while the opposite side is the south pole.
