I NEED 3 TO FIVE SENTENCES Graphite and diamond are minerals that have the same chemical composition. Describe the physical properties of these two minerals

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.

What is the measurement of how fast an object moves relative to a reference point?
