Find the output current $i_o$ in the circuit shown below using superposition, where $v_s = 32cos(9t)V$. Given: $i_{o1}$ is the value of phasor $i_o$ when only 20 V source is on and $i_{o2}$ is its value with $v_s(t)$ on only. The current $i_{o1} = \text{________} A$ (Calculate to 2 decimal places) The current $i_{o2} = I_{o2}\angle\theta$ A, where: $I_{o2} = \text{________} A$ (Calculate to 2 decimal places) $\theta = \text{________} deg$ (Calculate to 2 decimal places)

The index of refraction for a certain type of glass is 1.645 for blue light and 1.611 for red light. A beam of white light (one that contains all colors) enters a plate of glass from the air, $n_{air} \approx 1$, at an incidence angle of 35.55$^\circ$. What is the absolute value of $\delta$, the angle in the glass between blue and red parts of the refracted beams?

7) A ball is thrown in the air at an angle of 40° to the ground. If the maximum height it reaches is 10 m, what is the ball's initial velocity? (Take Earth's gravity as 9.8 m/s2.) (10 points) 8) You hit a ball horizontally from the top of a cliff that is 80m tall. The ball has an initial velocity of 10.0m/s. What is the horizontal range of the ball? (10 points) 9) Two objects, with the same size and weight, are thrown from the top of a building at the same time. Standing on the edge of the roof, the first is thrown straight down the side of the building with an initial velocity of 2.5m/s while the second is thrown at 5.0m/s at an angle 30° below horizontal. Which will hit the ground first if the building is 60m high? (10 points)

Please explain how you arrived at the answer. The combination of my professor lacking the ability to teach us, coupled with my innate inability to understand economics well, makes for a nightmarish class. YOU WILL NOT RECEIVE POINTS IF YOU DO NOT SHOW WORK/EXPLAIN. Thank you! OPEC announced recently that its member countries - a group of 13 oil-producing nations - will cut oil production in an attempt to raise prices. Will it work? In traditional economic theory, such production-fixing is hard to enforce because individual members of a cartel have an incentive to ignore their agreed-upon quotas. After all, if a member of the cartel produces more than it has agreed to produce, but everybody else sticks to the game plan, it can enjoy the benefits of rising prices and receive higher revenue. Assume global demand for oil is given by O = 34 - P (in billions of barrels) and variable cost conditions to both supply groupings are: VC = 10Qi Fill in the missing entries in both (i) the table and (ii) the payoff matrix below, and determine whether an equilibrium exists in the payoff matrix.
