LO1.5The Certified Public Accountant (CPA) exam is a uniform exam that is administered by a national organization. Licenses, however, are issued by individual states.

Are they fairly consistent or drastically different from each other? A helpful resource is https://www.thiswaytocpa.com/. You may also find it helpful to search the board of accountancy for each state.Tax preparation is a large part of what many CPAs do. Students may be interested to know that a CPA (or any other licensing) is not required to prepare tax returns. Assume you know two friends who prepare tax returns for others, one is a CPA and one is not. Assume that both friends intend to move next year and will, therefore, prepare taxes in another state.

A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) (a) At takeoff, an aircraft travels at 60.0 m/s, so that the air speed relative to the bottom of the wing is 60.0 m/s. Given the sea level density of air as 1.29\ \text{kg/m}^{3} , how fast must it move over the upper surface to create the ideal lift? (b) How fast must air move over the upper surface at a cruising speed of 245 m/s and at an altitude where air density is one-fourth that at sea level? (Note that this is not all of the aircraft’s lift—some comes from the body of the plane, some from engine thrust, and so on. Furthermore, Bernoulli’s principle gives an approximate answer because flow over the wing creates turbulence.)
