3 (a) A moon is in a circular orbit of radius r about a planet. The angular speed of the moon in its orbit is 0. The planet and its moon may be considered to be point masses that are isolated in space. Show that r and a are related by the expression Po 2 = constant. Explain your working. [3] (b) Phobos and Deimos are moons that are in circular orbits about the planet Mars. Data for Phobos and Deimos are shown in Fig. 1.1. moon radius of orbit /m period of rotation about Mars Thours 7.65 Phobos Deimos 9.39 x 106 1.99 * 107

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
