Athin lens is made from a material with refractive index of 1.20. this lens may be used in either air (n = 1.00) or water (n = 1.33). which of the following is true?
a. if the lens is converging in air then it is diverging in water, and if it is diverging in air then it is converging in water.
b. if the lens is converging in air then it is converging in water, and if it is diverging in air then it is diverging in water.
c. if the lens is converging in air then it is diverging in water, but if it is diverging in air then it is still diverging in water.
d. if the lens is converging in air then it is still converging in water, but if it is diverging in air then it is converging in water.
e. it is impossible to know whether the lens will be converging or diverging in water just from knowing the refractive index of the lens and whether it is converging or diverging in air.

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.
