5. [20 points] Apply Kruskal's algorithm to the graph below. Show new intermediate graphs with the shaded edges belong to the forest being grown. The algorithm considers each edge in sorted order by weight. An arrow points to the edge under consideration at each step of the algorithm. If the edges join two distinct trees in the forest, it is added to the forest, thereby merging the two trees. B 49 E 10 30 2 C A 10 22 G 4 7 D 26 F 5 22

2. A plaintiff filed a complaint in a federal district court. The complaint asserted a state law claim based on a breach of contract against an individual defendant from whom \$50,000 in damages was sought. The individual defendant was the majority shareholder of the corporate defendant. None of the parties was a citizen of the same state. Does the federal court have jurisdiction over this action? a. Yes, because the defendant and plaintiff are from different states. b. No, because the plaintiff's breach of contract claim would not win anyway. c. No, because the amount-in-controversy requirement is not met. d. Yes, because the claim raises a federal question. 3. A man liked to exercise late at night in the gym located in his condominium. As he entered the gym one night, he heard a woman screaming for help. The man rushed over to the woman, who was trapped under an 80-pound barbell. The man lifted the barbell off the woman, but injured his back in his rush to help the woman. The woman thanked the man, and told him that she knew she should not have been lifting the barbell by herself because it was too heavy for someone her size. The man has brought a negligence action against the woman to recover for his back injury. Will he prevail? a. Yes, because the man's actions were reasonable given the woman's need for help. b. Yes, because the woman failed to exercise reasonable care. c. No, because the man had no affirmative duty to help the woman. d. No, because the man's own negligence was the cause of his injury. 4. An inexperienced unicycle rider takes a test run on the city streets. He tries to stop for a red light but his balance is so unsteady that he continues through the ready light and into the intersection. A vehicle is approaching from an intersecting street and has a full green light. The driver sees the unicycle ahead in the intersection but figures that the unicycle will be through the intersection by the time he gets there. He keeps driving and runs over the unicycle rider. The rider files a claim for negligence against the driver. What happens? a. The rider will win because the driver was more negligent than the rider. b. The driver will win because the rider was assuming the risk by entering the intersection against the light. c. The rider will win, but his award will be reduced because he was contributorily negligent. d. The driver will win because the rider went through the red light.

QUESTION 1 What is the difference between the U.K. and England? 1) The U.K. and England are two different countries. 2) The U.K. voted to leave the E.U. England did not. 3) U.K. refers to the state and England refers to the nation. 4) U.K. refers to the country after the fall of the British Empire and England refers to the country before the fall of the British Empire. 5) The U.K. includes four nations and England is one of those nations. QUESTION 2 What's one explanation for why Iran is so illiberal? 1) A majority of politicians in Iran support smaller government and less spending. 2) The Opium Wars made the country extremely suspicious of anything Western, including political liberties and democratic elections. 3) Shia Muslims tend to have less education than Sunni Muslims. As such, the country is backward and ignorant. 4) Tradition and history. There is no time in Iran's history when it was more liberal or more Western. To maintain that tradition and history, the Iranian government has to clamp down on any Western influence or dissent. 5) Widespread dislike of the Shah before the revolution does not mean a majority supports the current theocracy. The Iranian government needs to be illiberal because it essentially contains a whole other country within its political culture.

A car engine whose output power is 130 hp operates at about 12% efficiency. Assume the engine's water temperature of 77 °C is its cold-temperature (exhaust) reservoir and 480 °C is its thermal "intake" temperature (the temperature of the exploding gas-air mixture). What is the ratio of its efficiency relative to its maximum possible (Carnot) efficiency? Estimate how much power (in watts) goes into moving the car. Estimate how much heat, in joules, is exhausted to the air in 1.0 h.
