Kirby is conducting a literature review in preparation for his study of "expectations regarding the sharing of financial and practical responsibilities among married and cohabiting couples in which both partners are between the ages of 20 and 29." Conducting a keyword search on "couples" and "responsibility," Kirby has generated a lengthy list of research articles. He decides to shorten the list of potential articles by eliminating all articles that were not published in prestigious research journals. He will include all the remaining articles in his literature review. What is your opinion of Kirby's approach to selecting articles for the literature review?

Later in this course we will learn how to combine flip-flops to make transitions to desired outputs. The flip-flop is holding bit of information, waiting for a signal to change (memory). But in this example YOU are still making the transition by flipping a switch. How can we make the flip-flop change without us providing the input directly

This method will sell the seat in row i and column j unless it is already sold. A ticket is sold if the price of that seat in the array is 0. If the ticket is not sold, add the price of the seat in row i and column j to the totalSales and then set the price of that seat to 0 to designate it has been sold and return true since a sell was made. If the ticket was already sold, then return false.

A small object A is held against the vertical side of the rotating cylindrical container of radius r by centrifugal action. If the coefficient of static friction between the object and the container is μs, determine the expression for the minimum rotational rate ⋅ θ = ω θ·=ω of the container which will keep the object from slipping down the vertical side.
