Why is area called scalar quantity

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.

Place me with this question is my last question

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?
