A still atmosphere with steady saturation s; derive an integral expression for the distance a drop will fall in evaporating completely from initial size r0. Specify the droplet fall speed as some function r, ie, u=u(r) and use the approximate form of the the expression for the rate of growth of solution droplet with radius r.

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...
