## Which statement best describes a significant similarity between the AICPA and IESBA codes? Both codes incorporate the conceptual framework approach for evaluating threats when specific rules on a matter do not exist. Both codes contain specific ethics and independence provisions related to public interest entities. The codes combine the rules for members in business and public practice in one section. The codes contain the exact same provisions for corporate accountants.

## At a sudden contraction in a pipe, the diameter changes from D1to D2. The pressure drop Î”p that develops across the contraction is a function of the diameters, the velocity V2in the smaller pipe, and the fluid density rho and fluid viscosity Î¼ (assume the fluid is incompressible). Use the repeating variables D2, V2, and Î¼ to non-dimensionalize the remaining variables and determine a suitable set of pi terms. Show work and explain in detail why would it be incorrect to include the velocity V1in the larger pipe as an additional variable?

## Which of the following are TRUE concerning rectifier circuits? Select all that apply. a. The output of an ideal full wave rectifier is zero volts only when the input is zero volts. b. Half-wave rectifier circuits need a minimum of 4 diodes to operate. c. In an ideal full wave bridge rectifier, half of the diodes are in the ON state and half of the diodes are in the OFF state at any given time the input voltage is not zero. d. The output of an ideal half wave rectifier is zero volts only when the input is zero volts. e. A turn-on voltage of a diode (y,) greater than zero can cause the output of a full wave rectifier to be zero volts even when the input is not zero volts. f. An advantage of the half wave rectifier is that is can use a smoothing capacitor, while a full wave rectifier cannot.
