5kg mass is attached to a point by a 35 meter rope. The mass isreleased and falls in a circle. If the only forces acting on the mass during thefall are tension and gravity, find the tension in the rope at the bottom of theswing (when the rope is vertical)

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.
