Consider a flat plate at zero angle of attack in a hypersonic flow at Mach 10 at standard sea level conditions. At a point 0.5 m downstream from the leading edge, the local shear stress at the wall is 280 N/m2. The gas temperature at the wall is equal to standard sea level temperature. At this point, calculate the velocity gradient at the wall normal to the wall. (Round the final answer to three decimal places.)

Consider the following two stocks, a and b. stock a has an expected return of 10%, 10% standard deviation, and a beta of 1.20. stock b has an expected return of 14%, 25% standard deviation, and a beta of 1.80. the expected market rate of return is 9% and the risk-free rate is 5%. security would be considered a good buy if we include the stock in a well diversified a portfolio because a. b, it offers better alpha b. a, it offers better alpha c. a, it offers better sharpe ratio d. b, it offers better sharpe ratio
