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

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
