There is a distinction between average speed and the magnitude of average velocity. give an example that illustrates the difference between these two quantities.

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.

What is a subatomic particle with a negative charge and very little mass?

The radius of an atom is closest in size to a
