Asmall piece of styrofoam packing material is dropped from a height of 1.90 m above the ground. until it reaches terminal speed, the magnitude of its acceleration is given by a = g โ bv. after falling 0.400 m, the styrofoam effectively reaches terminal speed, and then takes 5.40 s more to reach the ground.(a) what is the value of the constant b? s-1(b) what is the acceleration at t = 0? m/s2 (down)(c) what is the acceleration when the speed is 0.150 m/s? m/s2 (down)

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ร10ฮผ
