In science and physics what is the standard unit of measure for speed?

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

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.
