Two bullets of the same size, mass and horizontal velocity are fired at identical blocks, only one is made of steel and the other is made of rubber. the steel bullet has a perfectly inelastic collision with the block, while the rubber bullet has an elastic collision. which bullet is more likely to knock over the block, or are both equally likely to do so? justify your choice based on physics principles.

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.
