Kevin is 65 years old and is quite active. He decides to return to college and complete his bachelor's degree. Will he have the intellectual ability to do college level work? No, there is a sharp decline in intelligence after age 60, and it is very doubtful that he can learn and study adequately. No, cellular changes in the brain and nervous system will not permit him to learn and remember new information. Yes, crystallized intelligence (the ability to gain and hold onto new knowledge) has probably not declined. Yes, new technology allows his cohort to retain both old and new knowledge.

The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass ($n_2 = 1.50$) from air ($n_1 = 1.00$). Find the position ($x, y$ in cm) where the ray exits the glass. Or, if it does not exit the glass, find the ($x, y$) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs.

Microeconomic Tax Analysis: Problem set no. 1 Consider the case of payroll (labor) taxation when the supply of labor is inelastic (vertical) and the demand for labor downward sloping. The labor market to consider in the current experiment can be analyti- cally described as follows: TAX RULE (TR) $w^f = (1 + \sigma)w^h$, (1) LABOR DEMAND FUNCTION $w^h = H(L)$, (2) LABOR SUPPLY FUNCTION $L = \bar{L}$. (3) The variables employed represent $w^f$= wage paid by firms (unit labor cost faced by firms); $w^h$=take-home wage of workers (wage received by workers per unit of labor); $L$=quantity of labor (labor hours or employment, i.e. number of workers); $\sigma$=payroll tax rate (namely labor tax rate paid by firms); $\bar{L}$=exogenous (given) quantity of labor supplied. QUESTIONS What are the consequences of an increase of $\sigma$? What can be said about the payroll tax incidence? Is payroll taxation distortionary?

High-pressure Low-pressare Turbine Turbine Boiler 5 2 Pump Condenser A steam power plant features a two-stage turbine with reheat. Assume an isentropic efficiency of $\eta_r = 0.91$ for each turbine stage and $\eta_p = 0.94$ for the pump. The steam leaving the boiler is at 900 $^\circ$F and 1250 psia. The reheat occurs at 250 psia and the steam entering the low-pressure turbine is also at 900 $^\circ$F. The condenser pressure is 5 psia. (a) Draw the T-s diagram for the cycle. (b) Determine the net work for the cycle per unit mass. (c) Determine the heat input for the cycle per unit mass. (d) Determine the thermal efficiency of the cycle.
