Acar is moving at 12 m/s and has a mass of 600 kg. what is the kinetic energy of the car? (formula: )

Aphysical change is a change in the size, shape,, or stafe of matter true or false

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.

In an experiment, how can i change human errors? be specific.
