Intro You bought Samsung stock for $48 on April 1. The stock paid a dividend of $5 on July 1, and had a price of $57. It is now Oct. 1, and the stock price is $62. Part 1 What was the arithmetic average quarterly return? .189 Correct? $r_1 = \frac{57 + 5}{48} - 1 = 0.2917$ $r_2 = \frac{62}{57} - 1 = 0.0877$ $r_1 + r_2$ $0.2917 + 0.0877$ Attempt 2/10 for 9.5 pts.

Problem 3: A Pitot static tube is used to measure the velocity of an aircraft. If the air temperature and pressure are 5°C and 90kPa respectively, what is the aircraft velocity in km/h if the differential pressure is 250mm water column. Problem 4: A Pitot static tube is used to measure the velocity of water flowing in a pipe. Water of density $\rho$ = 1000 kg/m³ is known to have a velocity of $v$ = 2.5 m/s where the Pitot static tube has been introduced. The static pressure is measured independently at the tube wall and is 2 bar. What is the head developed by the Pitot static tube if the manometric fluid is mercury with density equal to $\rho_m$ = 13600 kg/m³.
