Calculations made in accord with NEC Article 220 indicate 110 amperes of continuous load and 40 amperes of noncontinuous load on a single-phase, 240/120-volt feeder. What is the minimum conductor size?

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

double the distance = divide strength by 4

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
