Data for June for Nahant Corporation and its two major business segments, North and South, appear below: Sales revenues, North $620,000 Variable expenses, North $359,700 Traceable fixed expenses, North $ 74,100 Sales revenues, South $478,400 Variable expenses, South $273,000 Traceable fixed expenses, South $ 61,900 In addition, common fixed expenses totaled $167,800 and were allocated as follows: $87,100 to the North business segment and $80,700 to the South business segment. A properly constructed segmented income statement in a contribution format would show that the segment margin of the North business segment is:

Problem 2. (24 points) A plane wave is represented in phasor form as $\vec{E} = \hat{x}E_1\exp(j\theta_1) + \hat{y}E_2\exp(j\theta_2)\exp(-jkz)$ where $E_1$ and $E_2$ are positive constants. Show clear steps to determine the polarization of this wave in the following three cases: (a) $\theta_1 = +\pi/2$, $\theta_2 = +j\pi/2$, (b) $\theta_1 = +\pi/2$, $\theta_2 = -\pi/2$, (c) $\theta_1 = +\pi/4$, $\theta_2 = +\pi/3$. Problem 3. (24 points) The wave electric field of a plane wave traveling in a medium ($\mu_1 = \mu_0$, $\epsilon_1 = 4\epsilon_0$) is given by $\vec{E} = \hat{x}E_0\exp[-j(2y - z)]$ where $E_0$ is a real constant. Find (a) the direction of wave propagation, (b) wave number, (c) wave frequency, (d) intrinsic impedance, (e) wave magnetic field $\vec{H}$, and (f) the time-average Poynting vector, $\vec{P}_{av}$.
