3 Outline the principles of computed tomography (CT scanning)​

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.

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion
