Consider a car driving around a circular track. once started, the driver maintains a speed of 45 m/h. compare the driver's velocity with his acceleration in this case.
a) the car is accelerating because it is changing direction but the velocity is constant.
b) the car is traveling at a constant rate of speed so it is not accelerating and the velocity does not change.
c) acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
d) the car is traveling at a constant rate of speed so it is not accelerating but the velocity changes because the direction the car travels is constantly changing.

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.
