An electron is launched at a stationary electron at 0.1c (3*10^7 metres per second). If it starts one metre away, how close will it get before it stops and turns around?

What are the theoretical properties of a gas at a temperature of 0 kelvin?

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.
