Question 1 (based on Blundell Q. 6.13) Consider the closure domain structure in a thin ferromagnetic sample as shown below. The easy axis is vertical in the plane of the picture and the hard axis is horizontal. The energy of the long 180° walls per unit area is $\sigma_w$ and the anisotropy energy density is K. Ignoring the contribution from the 90° walls (i.e. assume L >> D), show that $D \approx \sqrt{\frac{2\sigma_w L}{K}}$ Then estimate the length of the closure domains D for a sample of length L = 4 mm, assuming that $\sigma_w = 2 \times 10^{-3} Jm^2$ and that $K = 4 \times 10^4 Jm^{-3}$.

Problem 5 (20 points, continued on next page) A plane electromagnetic wave varies sinusoidally as it travels through vacuum in the +z direction. The magnetic field has its maximum value ($B_{max}$) at the origin at $r = 0$. At the origin at t = 0, the magnetic field points in the +x direction. (5a) Write a symbolic vector expression for the magnetic field as a function of time for a plane wave in terms of $B_{max}$, the wavenumber, the angular frequency, and the coordinates. Pay attention to the initial conditions described above. (5b) Write a symbolic expression using $B_{max}$ and constants of nature for the average power per unit area delivered by this electromagnetic wave. Problem 5 (20 points, continued from the previous page) A plane electromagnetic wave varies sinusoidally as it travels through vacuum in the +z direction. The magnetic field has its maximum value ($B_{max}$) at the origin at t = 0. At the origin at t = 0, the magnetic field points in the +x direction. The frequency of the electromagnetic wave is 100 MHz. The amplitude $B_{max} = 2.0 \times 10^{-7}$ T. (5c) Calculate the wavelength. (5d) Calculate the amplitude of the electric field at the origin at t = 0. (5e) Give the vector direction of the electric field at the origin at t = 0. $\hat{i} + \hat{j}$ $\hat{i} - \hat{j}$ $\hat{i} + \hat{k}$ $\hat{i} - \hat{k}$

Generating Energy: The bacterium is likely to utilize a combination of aerobic respiration and anoxygenic photosynthesis. In the absence of light, aerobic respiration would be the primary mode of energy generation. The organism might use the organic compounds present in the growth medium such as mannose and succinate as carbon sources for the tricarboxylic acid (TCA) cycle, leading to the production of NADH and FADH₂. These reduced coenzymes would then feed into the electron transport chain to generate a proton motive force for ATP synthesis. Draw out this cycle.

A satellite of mass m is in circular orbit of radius r$_0$ in a potential of the form $V(r) = -kr^{-3/2}$. (a) Use the Viral Theorem to find the orbital speed of the satellite. (b) What is the value of the one-dimensional effective potential at r$_0$, V$_{eff}$(r$_0$), for this situation? (c) Sketch V$_{eff}$ as a function of r for this potential, labeling your axes carefully. The satellite is now given an impulse which increases its kinetic energy by 20%. (d) On a copy of the effective potential from (c), sketch the new V$_{eff}$ if the impulse is radial. Qualitatively indicate on your plot the new total energy of the satellite and the apsidal distances (turning points) of the new orbit. Your plot should clearly indicate how the effective potential has changed between parts (c) and (d). (e) Repeat part (d) if the impulse is angular. Again your plot should indicate the difference between (c) and (e).
