What will be the resistance of this wire in terms of R if it is stretched to five times its original length, assuming that the density and resistivity of the material do not change when the wire is stretched. (Hint: The amount of metal does not change, so stretching out the wire will affect its cross-sectional area.)

1) Two particle Hamiltonian Consider the Hamiltonian for a system of two identical particles that may be interacting with one another \hat{H} = \frac{\hat{p}_1^2}{2m} + \frac{\hat{p}_2^2}{2m} + V(x_1, x_2) a. Argue or show that if the two particles are identical, $V(x_1, x_2) = V(x_2, x_1)$ b. Evaluate the commutation relation $[\hat{H}, \hat{p}_{12}]$. What does your answer tell you? c. A quantum system of two identical particles starts out in a symmetric state and evolves in time. How does the symmetry change as a function of time?
