According to the U.S. Census Bureau, the population of the United States in 2008 was 304 million people. In addition, the population of the United States was growing at a rate of \( 1.1 \% \) per year. Assuming this growth rate continues, the model \[ P(t)=304 \cdot(1.011)^{t-2008} \] represents the population \( P \) (in/millions of people) in year \( t \). According to the model, when will the population be 475 million people? Be sure to round your answer to the nearest whole year. Year \( \square \)

Problem #5: A non-adiabatic turbine accepts superheated water (steam) at 1 MPa and 540 °C at a mass flow rate of 10 kg/s and with negligible velocity. The water exits the turbine at a pressure of 35 kPa. Heat is lost from the turbine at a rate of 500 kW to surroundings at 20 °C. The turbine power is 8 MW. Determine: a) the rate of entropy generation (W/K), b) the ideal turbine power if there were no heat loss (adiabatic) or irreversibilities in the turbine (MW). Inlet: H2O, 10 kg/s 540 °C, 1 MPa $Q_{out}$ Turbine Outlet: 35 kPa

A beam of small (non-relativistic) particles is shot through a diffraction grating to form an interference pattern on a screen. Which of the following changes to the system will approximately double the separation between neighboring bands in the interference patterns. Assume only one change at a time is applied, and that the small-angle approximation is valid. I. Increase the velocity of the particles by a factor of 2 II. Increase the mass of the particles by a factor of 2 III. Decrease the velocity of the particles to 1/2 its prior value. IV. Decrease the mass of the particles to 1/2 its prior value A. (I) and (II) only B. (III) and (IV) only C. (I) and (IV) only D. (II) and (III) only E. None of the suggested options would double the separation between bands.

Use the following information for questions 5-9. A study was conducted to assess the association between benzene exposure and leukemia 40,000 workers occupationally exposed to benzene and 52,000 workers not occupationally exposed to benzene by baseline were followed for 10 ycars.At the end of the ten years there were 792 cases of lcukemia among benzene-exposed workers and 92 cases among the unexposed workers. Before you begin answering the questions,use the information above to fill in the following contingencytable: DISEASE EXPOSURE YES NO TOTAL 40,000 YES NO 52,000 TOTAL 884 91,116 92,000 5.Which of the following is an advantage of this type of study?(1 point) A.It's inexpensive. B.It's practical for rare discases. C.It permits direct observation of risk D.Attrition is beneficial. 6. Based on the study design,what is the correct measure of association you would use?2 points) A.Incidence rate B.Pearson's r C.Odds ratio D.Relative risk 7. Based on your answer in question 6,calculate the appropriate measure of association. Answers may vary duc to rounding,so choose the closest value to what you calculate.(2 points A.2.16 B.11.00 C.5.62 D.0.45 of association in Question 7?(2 points) A.There is no association between occupational exposure to benzene and leukemia B.The risk of leukemia in those occupationally exposed to benzene is greater than the risk of leukemia in those not occupationally exposed to benzene. C.The odds of leukemia increases as the odds of cxposure to benzene increases. 9. Which of the following would indicate that the association betwcen occupational benzene exposure and leukemia is statistically significant?(1 point) A. The 95% confidence interval does not contain I and p>0.05 B. The 95% confidence interval does contain I and p>0.05. C,The 95% confidence interval docs contain 0 and p>0.05. D. The 95% confidence interval docs not contain 0 and p0.05. E.The 95% confidence interval does not contain 1 and p0.05. F. The 95% confidence interval does not contain 0 and p>0.05
