Estimate the electrical resistivity (in ?-m) of metal Y containing (1.292x10^0) at% of metal Z at (1.2756x10^2) °C, given the following information:
The resistivity of pure Y at 0oC is (1.5140x10^-8) ?.m. The change in resistivity per degree celcius is (6.10x10^-11) ?.m/C. The resistivity changes with concentration as per the equation: A X1 (1-X1), where A is (1.424x10^-6) ?.m and X1 is the atom fraction of element Z.
Assume that all of the (1.292x10^0) at% of metal Z goes into solid solution in metal Y.
As always, use scientific notation in the form X.YZ x 10^n.
Note: Your answer is assumed to be reduced to the highest power possible.
