Q. If 3.00 10-3 kg of gold is deposited on the negative electrode of an electrolytic cell in a period of 2.62 h, what is the current in the cell during that period? Assume that the gold ions carry one elementary unit of positive charge.

Q. A gun shoots bullets that leave the muzzle at 213 m/s. If a bullet is to hit a target 160.4 m away at the level of the muzzle, the gun must be aimed at a point above the target. (Neglect air resistance.)
