Equation 12.1 suggests that we can improve resolution by increasing ∆t r, or by decreasing w A and w B (Figure 12.12). To increase ∆t r we can use one of two strategies. One approach is to adjust the separation conditions so that both solutes spend less time in the mobile phase—that is, we increase each solute’s retention factor—which provides more time to effect a separation.
The law of demand assumes that all other variables that affect demand (which we explain in the next module) are held constant. We can show an example from the market for gasoline in a table or a graph. Economists call a table that shows the quantity demanded at each price, such as Table 3.1, a demand schedule. In this case we measure price in ...
Mar 14, 2018 · To continue with the above example, suppose you bring in an additional employee at a total cost to your business of $50,000.

The period of a sound wave is the time it takes for an air molecule to oscillate back and forth one time. The wavelength of a sound wave is the distance between two compressed regions of air. People get these mixed up because there's an alternate way to create a graph of this sound wave. Consider this.
