A 4.88 x 10-6 C charge moves 265 m/s perpendicular (at 90°) to a magnetic
field of 0.0579 T. What is the magnetic
force on the charge?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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 mini-refrigerator fire was most likely caused by what type of wiring?
