(d) There were 54,633 deaths in motor vehicles in 1970 in the same country and 37,461 in 2016. Compare the rate of deaths (in deaths per 100,000 people) for these two years. The population in 1970 was 206 million. (Round your answers to one decimal place.) 1970 deaths per 100,000 people 2016 deaths per 100,000 people

1. (60 pts) Respiratory gas exchange depends on the ventilation-perfusion ratio $\dot{V}$/Q. a. Calculate PCO2 (arterial=alveolar) vs $\dot{V}$/Q = 1 for venous P$_v$CO2=45mmHg. b. For PIO2=150mmHg (FIO2=0.21), solve for the corresponding PO2 (arterial=alveolar) when $\dot{V}$/Q = 1. c. Plot PCO2 vs $\dot{V}$/Q for the range 0.1 ? $\dot{V}$/Q ? 10. d. Plot PO2 vs $\dot{V}$/Q for the range 0.1 ? $\dot{V}$/Q ? 10. e. Plot PCO2 (vertical) vs PO2 (horizontal) parameterized by 0.1 ? $\dot{V}$/Q ? 10 . f. Discuss your results in part (1.e).

Homework 4 Short Answer Question Liza's utility from consuming two goods, $x_1$ and $x_2$, is $U(x_1, x_2) = A(x_1)^\alpha (x_2)^\beta$, where $A$, $\alpha$, $\beta$ are positive numbers. The prices of the two goods are $p_1$ and $p_2$, and Liza's income is $w > 0$. a) Set up the constrained maximization problem and solve for Liza's optimal consumption bundle. b) How does Liza's optimal consumption bundle change in her income and the prices? What is the economic intuition for your results?

5.8 The drawing shows two views of a simple lawn sprinkler. The flow rate of water is 1 l/s and it enters the sprinkler with a velocity whose direction passes through the axis of rotation of the sprinkler head. The flow is divided evenly between the two outlet nozzles, each of which has an exit area of 30 mm². The nozzles are at a radius of 200 mm from the axis of rotation and their centrelines lie in the horizontal plane but at angle of 30° from the tangential direction, as shown. (a) Determine the moment which must be applied to hold the sprinkler head stationary. (b) If the head is rotating at a steady 500 RPM, what resisting moment is being applied to the sprinkler head? (c) If the head is allowed to rotate freely with no resisting moment, what is the rotational speed of the sprinkler in RPM? (Ans. 2.89 Nm, 0.792 Nm, 689 RPM) NOZZLE A=30 mm² y z 200 mm Radius 30° x WATER 1 l/s (NOT TO SCALE) x
