Write a journal response examining the value of auctions in the economy by addressing the following items:IntroductionExplain the difference between oral auctions and second-price auctions, including how they work and their results.Use the expected value information to illustrate how having more bidders in an oral auction will likely result in a higher winning bid.Explain how the number of bidders in a common value auction affects the outcome of the auction. Relate this to the effect on price in different market structures based on the number of producers. Auctions lead to outcomes where buyers reveal their value for the products being auctioned. To successfully price discriminate, firms often rely on buyers revealing their value for products. Explain the conditions necessary for firms to be able to price discriminate.Conclusion

Any basketball fan knows that Shaquille O'Neal, one of the NBA's most dominant centers of the last twenty years, always had difficulty shooting free throws. Over the course of his career, his overall made free-throw percentage was 53.3%. During one offseason, Shaq had been working with an assistant coach on his free-throw technique. During the next season, a simple random sample showed that Shaq made 26 of 39 free-throw attempts. Suppose that one wants to test whether Shaq has improved his free-throw shooting. Then the two hypothesis for this test are as follows: $H_0: p = 0.533$ $H_a: p > 0.533$ Suppose that the p-value obtained is 0.0465. What is the result when we test this claim at 0.05 significance level? No decision can be made due to insufficient information. Fail to reject $H_0$ i.e. there is not statistically significant evidence that Shaq has improved his free-throw shooting. Reject $H_0$ i.e. there is statistically significant evidence that Shaq has improved his free-throw shooting.

[4] The equation of motion under gravity of a mass element at the surface of a star of mass M is $\frac{d^2r}{dt^2} = \frac{-GM}{r^2}$ (neglecting internal pressure). If the star collapses from an initial radius R to some new radius r, derive an expression for the velocity v acquired by the mass element. [5] Derive the formula for the dynamical timescale of a star of mass M and radius R. Use this formula to estimate the dynamical timescale for Zeta Orionis, an 09.5 supergiant with a mass that is 33 times that of the Sun and a radius that is 20 times that of the Sun.

Part A The emission line used for zinc determinations in atomic emission spectroscopy is 214 nm. If there are 7.50\times10^{10} atoms of zinc emitting light in the instrument flame at any given instant, what energy (in joules) must the flame continuously supply to achieve this level of emission? Express your answer numerically in joules.
