A large cooler is filled with water, as shown below. A large yellow cooler with a white valve at its bottom. How does the valve on the cooler compare with the switch in an electric circuit? Opening the valve allows water to flow, just like opening a switch allows charges to flow. Opening the valve stops the flow of water, but closing a switch stops the flow of charges. Closing the valve stops the flow of water, but opening a switch stops the flow of charges. Closing the valve allows water to flow, just like closing a switch allows charges to flow.

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

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
