Two metal objects have net charges of +70 pC and -70pc, which result in a 20V potential difference between them.
(a)What is the capacitance of the system?
(b)If the charges are changed to +200pc and -200pc, what does the capacitance become?
(c)What does the potential difference become?

Some states require an expansion tank installed with a pressure reducing valve with or without a bypass feature. California State code is not specific on wether this creates a closed system. I would like to know if the Uniform Plumbing code is more specific on this matter?

I'm designing a project to work that is plugged into a wall socket (in the US). Does the appliance automatically draw whatever it needs? If that is true, does that mean you could take out the batteries of a remote control and plug the connectors to the batteries into a wall socket and not have it get fried? How exactly does it work?

What is the difference between Construction Engineering, Con. Engr. & Management, and Con. Engr. Technology? All the programs that I have looked at seem pretty similar, but some are acreditted differently than others. Also, why the Management or Technology? Do those make the programs different from just a straight Con. Engr program? Thanks in advance for any info.

I have seen various web-sites that show that someone pedaling a bike that is hooked to a a generator can power various appliances. These web-sites say things like if you pedal for an hour you can power a laptop for three hours. Or they say that you can charge a 12 volt battery. What I want to know is the dollar value of electric that one could generate by pedaling for one hour on a bike that is hooked to some sort of electric generator. An estimate of the cost of each kilowatt hour would be fine.
