Activity Level pH A biologist investigating enzyme functions plotted the activity of a particular enzyme (y-axis) versus pH (x-axis). Experiment A was performed at 30°C, experiment B at 10°C, and experiment C at 100°C. a) What are the optimal pH and temperature for this enzyme? [1 mark] b) What is the function of an enzyme? [1 mark] c) Why was there no enzyme activity detected during experiment C? [1 mark]

Q3: (7 Marks) An ideal gas, initially at 30°C and 1 bar, undergoes the following cyclic processes in a closed system. In mechanically reversible processes, it is first compressed adiabatically to 6 bar, then cooled at a constant pressure of 6 bar to 30°C, and finally expanded isothermally to its original pressure. Calculate Q, W, \Delta U, and \Delta H for the cycle.

7. Distinguish between direct (prohibition), indirect pollution controls (e.g. carbon taxes) and market mechanisms (e.g. cap and trade). Why would the business class prefer cap and trade? 8. Contrast GDP with the Genuine Process Indicators (GPI) consider-pollution, the depletion of natural resources, crime and income distribution in your answer. Contrast GDP and GPI growth rates 9. The World Economic Forum rankings suggest that high tax and spend countries are the most competitive in the world. How would crowding-in help to explain this. Discuss Norway and Alberta using the same framework. 10. Why does the left think the Canadian and US governments has used right-wing policy for the past four decades in order to boost profits? Include crowding-out and crowding-in, monetary policy, fiscal policy, deficit and debts, regulation, the natural rate of employment, GDP growth, trade and inflation.

Question 4 A jet of water having a velocity of (50 m/s) impinges a series of a curved vanes at an angle (15°) to the line of motion of the vane. Angles of vanes at inlet and exit are ($\theta_1 = 30^\circ$ and $\theta_2 = 15^\circ$). Assume frictionless conditions, Find the following from triangles velocities analysis at inlet and exit of the vane. a- The velocity of the vane (u) to avoid shock at entry. b- The absolute velocity at exit ($V_2$). c- The power obtained in (h.p) from 10 series vanes if diameter of jet ($d_{jet} = 0.2$ m).
