A car's acceleration is 32 m/s2 at time t = 3.0 s. The acceleration has been doubling every second since t = 0. If at t = 3.0 s the car is producing 1000 N of force, how much force was it producing at t = 0 s?

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.
