The electrical resistance of a wire varies directly as its length and inversely as the square of its diameter. a wire with a length of 200 inches and a diameter of one-quarter of an inch has a resistance of 20 ohms. find the electrical resistance in a 500 inch wire with the same diameter.

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
