3. For the electric circuit shown in figure (1) $u_0(t)$ (the unit step function), is the input and the initial conditions are, $i_L(0)=0$ and $V_c(0) = 0.5V$ measure the voltage across the resistance, inductor and capacitance by using Matlab / Simulink program. R L 10 ? 1/4 H C + i(t) 4/3 F v_s(t) = u_0(t) Fig. 1 4. Repeat the problem 3, modeling the circuit using differential equation to find the voltage across the resistance, inductor and capacitance.

Problem 3: (a) Determine which of the following are waves. D1(x,t) = e^(-a(x-vt)^2) D2(x,t) = Do sin(kx^2 + wt^2) D3(x,t) = Do sin(kx)cos(wt) The sun emits EM waves with vacuum wavelength λ. By the time these waves reach the surface of the Earth, they are essentially plane waves. (b) Take z to be towards the center of the Earth and z = 0 to be the surface of the Earth. If E(0,0) = Eo, where Eo is the amplitude of the electric field, write down expressions for E(z,t) and B(z,t) near the surface of the Earth in terms of the given quantities and the speed of light, c. (c) The sun radiates a time-averaged power of Ps. What is the time-averaged intensity (time-averaged magnitude of the Poynting vector) of EM radiation hitting the Earth's surface, which is a distance dE away from the sun? (d) Since the time-averaged intensity of an electromagnetic plane wave is also ρcE, determine the amplitude of the magnetic field near the Earth's surface in terms of the time-averaged power radiated by the sun.

2. (25 points) A heat engine is driving a heat pump and producing a power (work rate) output ($W_{net}$) as shown in the figure. Assume $T_{H1}$ and $T_{H2}$ are identical but higher than the ambient temperature $T_L$. Determine for each of the three cases shown below if the combined system (heat engine-heat pump) satisfies or violates the first law and the 2nd law. Explain why for all cases. $T_{H1}$ $T_{H2}$ $W_{net}$ $Q_{H1}$ $Q_{H2}$ Heat Heat Engine $W_1$ $W_2$ Pump Combined system $Q_{L1}$ $Q_{L2}$ $T_L$ $Q_{H1}$ [kW] $Q_{L1}$ [kW] $W_1$ [kW] $Q_{H2}$ [kW] $Q_{L2}$ [kW] $W_2$ [kW] Case I 6 4 2 3 2 1 Case II 6 4 2 5 4 1 Case III 3 2 1 4 3 1

Regions 1 and 2 have permittivities $epsilon_1 = 2epsilon_0$ and $epsilon_2 = 5epsilon_0$. The regions are separated by a plane whose equation is $x + 2y + z = 1$ such that $x + 2y + z > 1$ is region 1. If $mathbf{E}_1 = 20hat{x} - 10hat{y} + 40hat{z}$ V/m, find a. the normal and the tangential components of $mathbf{E}_1$, b. $mathbf{E}_2$.
