NEC® requires that loads be evenly proportioned (or balanced) among the different circuits in a panelboard. This means that when everything is connected to all circuits is ON then the circuit in ___ feeder conductors are equal, or as close as possible. (a) either "hot" and the neutral (b) the two "hot" (c) the ground and the neutral

Now that the first three steps have been explained, identify the next three steps, in order. calculate the magnitude of r sum vector components calculate a and b magnitudes calculate the direction of r, calculate x,y components step 4 step 5 step 6

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

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.
