How have the competing explanations' experiments on atoms affected the development of the atomic model?

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.

Aforce of 40n applied at the end of length 4m and diameter 2.00mm process and extension of 0.24mm,calculate the stress on the wire, strain in the wire and the young modulus for the material of the wire
