Lawrence Summers served as secretary of the treasury in the Clinton administration and as director of National Economic Council in the Obama administration. He has been quoted as giving the following moral defense of the economic approach. "There is nothing morally unattractive about saying: We need to analyze which way of spending money on health care will produce more benefit and which less, and using our money as efficiently as we can. I don't think there is anything immoral about seeking to achieve environmental benefits at the lowest possible costs." Source: David Wessel, "Precepts from Professor Summers," Wall Street Journal, October 17, 2002. It would be more moral to reduce pollution, A. taking the cost into account because reducing pollution often reduces economic growth. B. taking the cost into account because money spent on pollution reduction is not available for other worthy activities. C. not taking the cost into account because pollution is potentially harmful to our health. D. taking the cost into account because the total cost of reducing pollution is likely enormous. E. not taking the cost into account because pollution reduction is typically associated with large benefits.

The bond strength of every individual bond is e = -2eV. The model is periodic in x-direction (blue boundaries), and has open boundaries in normal direction. Atoms on sites labeled with 0 are fixed. Jumps can only follow the x- and z-direction. The activation energy is composed of a term taking into account the difference in the number of bonds between the initial and final state Δn and a constant migration energy $E_{mig}$ = 1eV. The prefactor is $v_o$ = 10^12 s^-1 and the resulting jump frequency of an individual hop is given by: $v = v_o exp(- \frac{εΔn + E_{mig}}{k_BT})$, if Δn = $n_{final}$ - $n_{initial}$ < 0 $v = v_o exp(- \frac{E_{mig}}{k_BT})$, if Δn > 0 (a) (1P) Does the given model fullfill the detailed balance criterion? Provide a proof for your statement. (b) (1P) What is the possibie jumps and corresponding activation energies of the atoms on sites 12 and 9 for leaving their places? (c) (1P) Which of all atoms are most likely jumping first? Explain your solution.

A spring has a spring constant of 1787 N/m. You place the spring vertically with one end on the floor. You then drop a 1.2 kg book onto it from a height of 0.8 m above the top of the spring. Find the maximum distance the spring will be compressed. Express your answer with the appropriate mks units. Part 2: Block sliding up a hill A 14 kg block slides up a hill to a height of 7.7 m. If 458 J of thermal energy are generated, how fast was the block going at the bottom of the hill?

\dot{x}_1 = -2x_1 + x_2 \\ \dot{x}_2 = x_1 - 2x_2 \\ with initial conditions x_1(0) = 1, x_2(0) = 1, \dot{x}_1(0) = 0, and \dot{x}_2(0) = 0. This model describes the oscillations of a system of two masses connected with three springs to each other and to a wall on the left and to a wall on the right. Hint: please take special care tracking signs, in particular when you are putting the system into a matrix form. A simple sign error can cause your solution to look like exponential growth or decay instead of an oscillation. Checking the answer for errors is all the more important in this case.

Please answer all parts of 8! 8. (1.5 pts) Consider the following digital circuit with 3 inputs: + 0 0 0 0 Y 0 0 1 1 0 0 1 1 Z 0 1 0 - 0 F (courtesy of Edward Bosworth) (a) Complete the truth table to the right that describes the output of the circuit. 1 1 1 0 - (b) A Boolean expression for the circuit above is: F = X v Y v ((Y v Z) v -X) Using your truth table, write an equivalent Boolean expression for the circuit above that does not use the exclusive-or operator. Your expression should be of the form: F = A V where each sub-expression corresponds to a row of the truth table. F = X v Y v ((Y v Z) v -X) (c) Bernie is writing a Python program to display the text of an amendment to the Constitution of the United States given the amendment's number as an integer. There are 27 ratified amendments. If the number is not between 1 and 27 (inclusive), he wants to display an error message. He writes the following Python statement: if not (number >= 1 and number < 28): print("ERROR: Invalid number of a ratified amendment.") Rewrite the statement using DeMorgan's Law to simplify it: if (number < 1 or number >= 28): print("ERROR: Invalid number of a ratified amendment.")
