Help... The current price of gold costs $58,887.31 per kilogram while silver costs $864.19 per kilogram. The density of gold is 19.32 g/cm^3 while silver is 10.49 g/cm^3.
1a) If you desired to create electrical wires that are both 10 m long, how thick or thin would the gold wire be compared to the silver wire if you desired for them to have the same electrical resistance? (i.e. - find the difference in diameters.)
1b) Given the situation in part a, how much more would the gold wire cost in comparison to the silver wire?
