Rain that tends to fall in bands on earth is caused by which of the following?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?

The ability to make things happen is also called a. heat b. force c. matter d. energy
