4. The circuit is shown in Fig. 5 exhibiting a $V_{ab}$ of 0.6 V measured from a voltmeter. Given $V_{ex}$=10 V, $i_1$=0.1 A, $R_1$=40 Ω, $R_2$=300 Ω, $R_3$=700 Ω, $R_5$=150 Ω, and with $R_4$ being an unknown resistance with a ±2% tolerance: (1-a) Determine $V_{R1}$. (1-b) Determine the resistance color code of $R_4$ (refer to Fig. 6). (1-c) Assuming $R_4$ breaks (resulting in an open-circuit) during the experiment. With all other resistors remaining unharmed, determine the new $V_{ab}$ and the new total power consumption of the circuit in milli-Watt (mW). $\frac{R_2}{R_3} = \frac{R_4}{R_5}$ $V_{ab} = V_{ex} (\frac{R_3}{R_2+R_3} - \frac{R_5}{R_4+R_5})$ $V = IR$ $V = 0.1(40)$ $V_{R1} = 4V$

2. If the ground state of a particle in a spherical square well is just barely bound, show that the well depth and radius parameters $V_0$ and $a$ are related to the binding energy by the expansion \begin{equation*} \frac{2mV_0a^2}{\hbar^2} = \frac{\pi^2}{4} + 2ka + \left(1 - \frac{4}{\pi^2}\right)(ka)^2 + ... \end{equation*} where \begin{equation*} \hbar k = \sqrt{-2mE} \end{equation*} The deuteron is bound with an energy of 2.226 MeV and has no discrete excited states. If the deuteron is represented by a nucleon, with reduced mass, moving in a square well with $a = 1.5$ fermi, estimate the depth of the potential. 3. Given an attractive central potential of the form \begin{equation*} V(r) = -V_0e^{-r/a} \end{equation*} solve the Schrödinger equation for the S states by making the substitution \begin{equation*} \xi = e^{-r/2a} \end{equation*} Obtain an equation for the eigenvalues. Estimate the value of $V_0$, if the state of the deuteron is to be described with an exponential potential (see Problem 2 for data).

Refer to the financial statements and the Notes to the financial statements for the company you have selected to respond to the following questions Include the url to access the 10-K that you are using (and test it to be sure that the link works). a) Is your company a merchandising company or a manufacturing company? How many categories of inventory are presented on the balance sheet or disclosed in the notes? b) Does the company use the same inventory cost flow assumption (LIFO, FIFO, average) for all of its inventory? c) Does the company report on the balance sheet that inventories are valued at lower of cost or market or lower of cost or net realizable value\---or is it disclosed in the notes? d) Does the company estimate ending inventory using Retail Inventory method\---or some other GAAP inventory costing method? e) Compute the company's inventory turnover. The formula is shown below; show the amounts used. Is their inventory turnover good or not? How do you know? Inventory turnover = cost of goods sold / average inventory
