9. Molly, a stray dog in the city, runs one complete lap around the base a building in exactly 10.0 minutes. The building has a rectangular base with dimensions 132
meters by 153 meters. Find Molly's (a) total distance, (b) total displacement, (c)
average speed, and (d) average velocity.

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

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
