I can help you draw the ray diagram.
<span>A belt drive requires less maintenance, lasts longer and is cleaner. It also delivers a smoother ride, which is why this type of drive system is most commonly used on cruiser motorcycles.A chain drive, on the other hand, delivers power more economically than a belt drive, and it sends more of the power that the engine produces to the wheel. While they require more maintenance, the improved performance means they are the more common type of drive method.</span>
Explanation:
In a chemical reaction, when mass is conserved , the number of atoms or moles of the reactants must be equal to the number of moles or atoms in the products side.
From the diagram, we should carefully look to see if the number of atoms that makes up the reactants are equal to those on the product side.
For example:
A + B → AB
Here, mass is conserved because, on the reactant side, we have 1 atom of A and on the product side we have 1 atom of A
For B, on the reactant side, we have 1 atom of B and on the product side, we have 1 atom of B.
iron, cobalt and Nickel is the answer
Answer: C. Charge and distance
