each term on the right-hand side of the equations from the units of the physical quantity on the left-hand side. (a) Because x is in meters, C1 and C2t must be in meters: (b) Because x is in meters, ½C1t2 must be in meters: (c) Because v2 is in m2/s2, 2C1x must be in m2/s2: (d) The argument of trigonometric function must be dimensionless; i.e. without units. Therefore, because x C1 is in m; C2 is in m/s C1 is in m/s 2 C1 is in m/s 2 C1 is in m; C2 is in s −1 Systems of…

dissatisfaction with available electronics textbooks. Plenty of textbooks exist to describe things, but few really explain things well for students, and the field of electronics is no exception. I wanted my book(s) to be different, and so they were. No one told me how time-consuming it was going to be to write them, though! The next few years’ worth of my spare time went to developing a set of question-and-answer worksheets designed to teach electronics theory in a Socratic,…

(Controller). Of course, the small business owner/manager should make sure that the Controller is using good internal accounting controls. Recognizing the Need for Controls John’s father-in-law was a small business owner/manager for many years. He told him that based on his experience, there’s a little bit of larceny in everyone’s heart. Unfortunately, he was right. He could have added that there’s a lot of larceny in the hearts of a few. An unpleasant fact of business is that some…
