3) Calculate the little bit of force that exists on the wee little electron if it's 2 points moving at 3.6 x 10 m/s in a magnetic field of 0.268 Tesla. The electron (e =
1.6x10-19 Coulombs) is traveling perpendicular to the field. *
1.5 x 10-16 N
7.5 x 10-12 N
15N

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

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.
