Consider a plane parallel-plate capacitor made of two strips of aluminum foil separated by a layer of paraffin-coated paperEach strip of foil and paper is 3.80 cm wideThe foil is 0.00400 mm thick, and the paper is 0.0350 mm thick and has a dielectric constant of 3.70What length should the strips be if a capacitance of 6.00 10-8 F is desired? (If, after this plane capacitor is formed, a second paper strip can be added below the foil–paper–foil stack and the resulting assembly rolled into a cylindrical form—similar to that shown in the figure below—the capacitance can be doubled because both surfaces of each foil strip would then store chargeWithout the second strip of paper, however, rolling the layers would result in a short circuit.)answer in meters
a extra lively steel is a steel which could lose electrons very actual and type grow to be cations while a far less lively steel does not lose electrons actual and do type compounds so onlyan lively metals occurs in marvelous of reactivity sequence at the same time as much less lively metals happen low in sequence the version is because of the reality thatin the atoms of lively steel, tension of charm or valuable nuclear charge between nucleus and valence electrons are vulnerablefor that reason it could lose e- onlylively metals - potassium, sodium inactive metals, copper, lead, silver copper occurs very low in pastime sequence, even decrease than hydrogen for that reason, it is not so lively and can't displace hydrogen from acid and type compounds while mg is amazingly reactive and actual displaces hydrogen and types MgCl2 and H2 gas
