As the elevator starts, the scale has a constant reading of 599 n. as the elevator later stops, the scale reading is 385 n. assume the magnitude of the a person stands on a scale acceleration is the same during starting and stopping. the person. (a) detemine the weight n (b) determine the person's mass. acceleration of the elevator. (c) determine m/s

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. ×10μ
