A monoatomic ideal gas undergoes a cycle. The gas is initially at pressure $P_1 = 80$ kPa and volume $V_1 = 4$ lt. During the first leg of the cycle (1→2), the gas expands so that P is linearly proportional to V until the volume doubles and the pressure $P_2 = 120$ kPa. In the second leg of the cycle (2→3), the pressure remains constant while the volume increases to $V_3 = 16$ lt. In the third leg of the cycle (3→4) the pressure the gas decreases to $P_4 = 20$ kPa at constant volume. In the last leg of the cycle (4→1) the gas is compressed back to its initial volume while keeping the temperature constant at 400 K. 1. Sketch the P vs. V diagram of the cycle

3. How does lateral acceleration - side forces experienced in turns that are largely under driver control - affect nausea as perceived by bus passengers? The article \"Motion Sickness in Public Road Transport: The Effect of Driver, Route, and Vehicle\" (Ergonomics, 1999: 1646-1664) reported data on $x$ = motion sickness dose (calculated in accordance with a British standard for evaluating similar motion at sat) and $y$ = reported nausea (%). Values of dose in the sample ranged from 6.0 to 17.6. Regression Analysis: y versus x The regression equation is y = -8.715 + 1.536*x Predictor\tCoef\tStandard Error\tT-statistic\tProb>|T| Intercept\t-8.715\t5.687\t-1.533\t0.146 x\t1.536\t0.424\t3.622\t0.003 R-Sq = 46.7%\tRoot MSE = 5.280 a. What is the sample size $n$ here? b. Assuming that the simple linear regression model is valid for relating these two variables (this is supported by the raw data), interpret the estimate of the slope parameter. Calculate the 95% CI for the slope. c. Does the fitted model imply the true slope is significantly different from 0.5? What is the approximate $p$-value? d. Would it be sensible to use the simple linear regression model as a basis for predicting % nausea when dose is 5.0? Explain your reasoning. e. Suppose we observe $y = 0.80$ at $x = 30\%$ in the data. What value of wear loss would you predict when content is 30%, and what is the value of the corresponding residual observed?

2. (35 pts) Use more detail programming to compress some pages of English sentences by using greedy algorithm: (a) Draw a Huffman encoding tree for the following 10 characters with their frequencies: A (13), B(11), C(15), D(9), E(18), F(16), G(20), H(30), period(12), comma(10) (b) How many minimum number of bits can you represent the above characters? (c) Write a detail level of pseudocodes to process the Huffman encoding function. (You may use any language; You decide the number of bits representation.)
