Determine the momentum of a 6 kg object moving at 5 m. s-1 to the right

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

In an experiment, how can i change human errors? be specific.

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.
