Concept explainers
To determine the concentration of a purified protein sample, a graduate student used spectrophotometery to measure the absorbance given in the table below:
The absorbance of the sample, in is the rate of change of absorbance a with respect to concentration c, and a1 is the y -intercept.
(a) Find the equation of the line that describes the concentration absorbance relationship for this protein and determine the slope in of the linear relationship.
(b) Using the equation of the line from part (a). Find the concentration of the sample if this sample had absorption of 0.486.
(c) If the sample is diluted to a concentration of 0.00419 µg/ml, what would you expect the absorption to he? Would this value he accurate?
(d) Sketch the graph of absorbance a as a function of concentration c and clearly indicate both the slope in and the y -intercept.

- Tsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled.
