Explanation:

Point a is the highest. When it comes to potential energy, the higher you are, the more of it you have. Example, when you are at the top of a hill, you have the most potential energy. When you are at the bottom of the hill, you have the least amount of potential energy, and the most kinetic energy.

Hope this helps!!

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
