QUESTION 6 (3 points) Hydropathy of amino acyl residues can be determined by many different methods. In the partition method of determining hydropathy, partitioning of amino acid analogue (in which the alpha-amino group and the alpha- carboxyl group are both rendered unionizable) in water versus an organic solvent (e.g. octanol) is measured, to determine how hydrophilic or hydrophobic the R-group is. The experiment is set up as shown below: where "solute" is the amino acid R-group. Transferring to Reactant Product [Solute] H20 [Solute] octono File Preview A partitioning experiment with an amino acid analogue carrying the side chain "A" gives a calculated AG° value of 5.94 kJ/mol (pH 7.0, 25°C, 1 atm). 6.1 What is the ratio of the amino acid analogue in the water phase to that in the octanol phase? 6.2 Is the amino acid analogue hydrophobic or hydrophilic?

Question B4. [20 marks] a) If a and b are distinct positive numbers, find the maximum value of $f(x) = (-x)^a(1+x)^b$, where $-1 \le x \le 0$. b) Consider the function $f(x) = \cos 3x$. (i) Show that there exists $0 < \theta < 3$ such that $f(\frac{\theta}{3}) = 0$. (ii) By using a calculator, find an interval of length 0.1 that contains the $\theta$ you obtained in (i) above. c) Show that the function $f(x) = \frac{x^2}{x^2+1}$ has three points of inflection.

Problem 10.61 Water at 80°F flows at 5.4 ft/s through the 3 -in-diameter copper pipe at A. As the water is flowing, 4 it emerges from the showerhead that consists of 100 holes, each having a diameter of\frac{1}{16} in. The minor loss coefficient is $K_L = 0.45$ for the showerhead. Also account for the minor loss in the three elbows, the fully opened gate valve, and the tee. Neglect the minor loss at the pipe segment EC. For the copper pipe take $f = 0.016$. $\rho = 1.934$ slug/ft³. (Figure 1) Figure Part A Determine the pressure of water at A. Express your answer to three significant figures and include the appropriate units. $P_A = $
