2. A single layer FR 4 board (bottom is a ground plane) is operated at 2 GHz. The following questions arise: A) What is the width for a $Z_0 = 50\Omega$ copper trace ($\sigma = 5.8 \times 10^7 S/m$), for a 0.062" thick board. The manufacturer lists a dielectric constant of 4.34 at 1GHz and a dissipation factor of 0.017. The trace thickness is 1.5 mil. B) Does the skin effect influence the trace thickness? C) Based on the above dissipation factor, can you make predictions about the signal attenuation? How significant do you think the effect will be? What voltage signal attenuation in dB can you expect for a 30 cm long trace? Note: To answer C) requires some "deep" thinking.

Problem 1.3. Find a vector field $\vec{E}(\vec{r})$ in $\mathbb{R}^2$ such that: $\nabla \times \vec{E} = \vec{0}$, $\nabla \cdot \vec{E} = \rho$, where $\rho$ represents a point of charge $2\pi$ placed at the origin, $\rho(\vec{r}) = 0$ for $\vec{r} \neq \vec{0}$, and $\iint_{\mathbb{R}^2} \rho dA = 2\pi$.

T2 = 550 °C, P2 = 200 atm, T4 = 550 °C, P4 = 15 atm and T6 = 60 °C. The pump is adiabatic andreversible and both turbines are adiabatic with the isentropic efficiency of 0.87. Answer the followings: 1. Fill in Table 1. The temperature rise across the pump is given by ($\Delta T_{1-6} = \frac{\beta \times V \times T}{C_p} \times \Delta P_{16}$) where $\beta$ = 5.8 X 10<sup>-4</sup>/K, Cpwater = 4187 J/kg.k and T = T before the pump 2.
