1.Molybdenum (Mo) forms a substitutional solid solution with Tungsten (W). Compute the number of Mo atoms/cm3 for a Mo-W alloy that has 16.Wt%Mo-83.6Wt%W. The densities of pure Mo and W are 10.22 and 19.30 g/cm3, and the atomic weights are 95.94 and 183.85, respectively.
2.A wire has a resistance of 1.2×10-2 . What will the wire's resistance be if it is stretched to twice its original length without changing the volume of the wire?
