Homework Answers
a) Gini index is used as a gauge of income inequality and ranges from 0 (0%) to 1 (100%) with 0 representing perfect equality and 1 representing perfect inequality. Thus greater the Gini index , greater the income inequality in the population. Hence the statement is TRUE.
b) The horn of Gabriel has infinite surface area but finite volume. Hence the statement is FALSE.
c) FALSE.
d) A trapezoid is a 4-sided flat shape that has one pair of opposite sides parallel. Hence the statement is FALSE.
e) TRUE.

3. The Gini Index Problem How is possible to measure the distribution of income among the inhabitants of a given country One such measure is the Gini index, named after the Italian economist Corrado Gini, who first devised it in 1912. We first rank all households in a country by income and then we compute the percentage of households whose income is at most a given percentage of the country's total income. We define a Lorenz Curve y L(x) on...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
