A velocity vs. time graph for an object is shown. A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, Velocity in meters per second on the y axis, numbered 0 to 25. A line labeled W starts at the origin and ends at (1, 15). A line labeled X starts at (1, 15) and ends at (2, 20). A line labeled Y starts at (2, 20) and ends at (4, 20). A line labeled Z starts at (4, 20) and ends at (5, 0). Which parts of the graph represents the object moving at a constant, positive acceleration? W and X X and Y Y and Z W and Z

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.
