Erna Corporation is evaluating an extra dividend versus a share repurchase. In either case, $15,000 would be spent. Current earnings are $1.60 per share, and the stock currently sells for $48 per share. There are 2,500 shares outstanding. Ignore taxes and other imperfections. a. Evaluate the two alternatives in terms of the effect on the price per share of the stock and shareholder wealth per share. Note: Do not round intermediate calculations and round your answers to 2 decimal places eg 3316

DropSieg-4509 Corporation has two departments, Kids and Adults. The company's most recent monthly contribution format income statement follows Sales Variable expenses Contribution Margin Fixed Expenses Net operating income (loss) Total Department Kids Adults $4,200,000 $3,000,000 $1,200,000 2,000,000 1,500,000 500,000 2,200,000 1,500,000 700,000 2,200,000 1,300,000 900,000 0 200,000 (200,000) A study indicates that $150,000 of the fixed expenses being charged to the Adults Department are sunk costs or allocated costs that will continue even if the Adults Department is dropped. In addition, the elimination of the Adults Department will result in a 20% decrease in the sales of the Kids Department. If the Adults Department is dropped, what will be the effect on the net operating income of the DropSeg-4509 Corporation as a whole?

Liquid hydrazine (N$_2$H$_4$) is injected into a jet combustion chamber at 400 K, 1 atm and burned with 100\% excess air that enters at 700 K, 1 atm. The combustion chamber is jacketed with water. The combustion products leave the jet exhaust at 900K. In a test of the unit, if 50 kmol/hr of hydrazine are burned and water at 25 C enters the cooling water jacket at a rate of 100 kg/min and 1 atm, what is the temperature and phase state of the water (solid, liquid, vapor, or wet vapor) at the exit of the jacket? The reaction is: N$_2$H$_4$ (l) + O$_2$ (g) $\rightarrow$ N$_2$(g) + 2 H$_2$O (g) The heat of formation of liquid hydrazine is: $\Delta H^\circ_f$ = 44.7 kJ / mol The heat capacity of liquid hydrazine may be assumed constant at 139 J/mol K 5 point bonus: What is the dew point temperature of the exhaust gas? (This problem inspired by the cover of the 9th edition of the text.)

Question 2. [50 points] a. [10 points] Starting with $\int \vec{J} \cdot d\vec{a} = I$ prove the continuity equation $\nabla \cdot \vec{J} - \frac{\partial \rho}{\partial t} = 0$. b. [30 points] Recall that $\vec{B}(\vec{r}) = \frac{\mu_0 I}{4\pi} \int \frac{d\vec{l'} \times \hat{r}}{r^2}$ from Biot Savart. A finite length wire with current moving to the right is shown. i. Determine the magnetic field, at point P, a distance s above the wire in terms of I, s, and $\theta_1$ and $\theta_2$ (the angles that describe the endpoints of the wire as show.) ii. Determine the direction of the magnetic field at point P. iii. If the wire is extended so that it is very, very long (i.e infinite), determine the equation for the magnetic field from your answer in part i. iv. [points] Use Ampere's Law for the very, very long wire and determine the magnetic field. c. [10 points] Consider a very, very long solenoid with n turns/length and current I. Using Ampere's Law, determine the magnetic field inside the solenoid in terms of I, n. It may help to sketch a figure showing the solenoid and the Amperean loop.
