The canon on a battleship can fire a shell at a maximum distance of 39.5 km

a)Calculate the initial speed of the shell, in meters per second. Neglect air resistance to make the problem easier.

b)What maximum height, in meters, does it reach?

c)The ocean is not flat, because the Earth is curved. Take the radius of the Earth to be 6.38 x 10^3 km. How much lower, in meters, will its surface be 39.5 km from the ship as measured along a line that is tangent to the surface of the Earth at the location of the ship?

    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...
