What will happen if the value of g that is 9.8m/s^2 becomes zero???

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

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 are atoms of the same element with varying number of neutrons
