A uniform spherical shell of mass $M = 1.80 \text{ kg}$ and radius $R = 36.0 \text{ cm}$ can rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia $I = 4.00 \times 10^{-3} \text{ kg} \cdot \text{m}^2$ and radius $r = 6.00 \text{ cm}$, and is attached to a small object of mass $m = 7.00 \text{ kg}$. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen 1.00 m after being released from rest? Use energy considerations.

(20 pts) 1) Consider a spinless particle of mass $m$ and charge $q$ which moves under the influence of a 2-dimensional harmonic oscillator potential. The unperturbed Hamiltonian is $H^0 = -\frac{\hbar^2}{2m} \left( \frac{\partial^2}{\partial x^2} + \frac{\partial^2}{\partial y^2} \right) + \frac{1}{2} m\omega^2 (x^2 + y^2)$ A magnetic field pointing in the z-direction leads to the interaction $H' = -\vec{\mu} \cdot \vec{B} = -\frac{q}{2m} (\vec{L} \cdot \vec{B}) = -\frac{qB}{2m} L_z = -\frac{qB}{2m} (xp_y - yp_x)$ a) Find the first order correction to the energy of the ground state. b) Find the first order corrections to the energies of the first excited states. c) Find the new non-degenerate states in terms of the original states.

Current Attempt in Progress Figure (a) shows, in cross section, two long, parallel wires carrying current and separated by distance L. The ratio $i_1/i_2$ of their currents is 7.40; the directions of the currents are not indicated. Figure (b) shows the y component $B_y$ of their net magnetic field along the x axis to the right of wire 2. The vertical scale is set by $B_{y_s} = 6.8 \text{ nT}$, and the horizontal scale is set by $x_s = 21.9 \text{ cm}$. (a) At what value of $x > 0$ is $B_y$ maximum? (b) If $i_2 = 3.04 \text{ mA}$, what is the value of that maximum? What is the direction (into or out of the page) of (c) $i_1$ and (d) $i_2$?
