document.write( "Question 1050634: The resistance, R, of a wire varies directly as its length and inversely as the square of its diameter. If the resistance of a wire 3100 ft long with a diameter of 0.07 inches is 16262 ohms, what is the resistance of 900 ft of the same type of wire with a diameter of 0.05 inches? \n" ); document.write( "

$\"R=%28kL%29%2FD%5E2\"$
\n" ); document.write( " $\"k=%28RD%5E2%29%2FL\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"%2816262%280.07%29%5E2%29%2F3100=%28R%280.05%29%5E2%29%2F900\"$
\n" ); document.write( " $\"R=16262%28%280.07%29%5E2%2F%280.05%29%5E2%29%28900%2F3100%29\"$
\n" ); document.write( " $\"R=9254%29\"$
\n" ); document.write( "9254 ohms \n" ); document.write( "
