8. Consider the \"Chotikapanich\" model for a Lorenz curve, where \begin{equation*} L(x) = \frac{1}{e^k - 1}(e^{kx} - 1), \end{equation*} where k is an (as yet) unknown constant. (a) Check that, regardless of the value of k, for this formula we get L(0) = 0 and L(1) = 1. (b) Write one or two sentences explaining why it is important, in the context of distribution of income, that any Lorenz curve should satisfy the equations L(0) = 0 and L(1) = 1. (c) According to the Gini Index, which model shows greater income inequality for a country: a model with Lorenz curve given by the Chotikapanich model with k = 2.4, or by the Lorenz curve $L(x) = \frac{3}{5}x^3 + \frac{2}{5}x^2$?

Consider a small anchor of mass 10.2 kg and with a volume of 2.21 litre. The anchor is suspended from a scale and fully immersed in salt water. The scale shows the apparent weight of the anchor and indicates an apparent mass of 7.8743 kg. (The local acceleration due to gravity is 9.8079402 m/s$^2$.) (a) Sketch the situation including force vectors in your work book. (b) Determine the density of the salt water by calculation. Enter your result for (b), namely the salt water density to significant figures, including the correct unit, in the field below. Write a complete sentence.
