Are linear and angular momentum conserved separately? Now, such an object can be assumed to have a constant mechanical energy. But that is only one part of the story. The fact is, since each linear and angular momentum of this object is conserved, the respective components of its linear and angular energy also would be […]

Is triode a diode? Triode tubes A triode is much like the diode vacuum tube, except that it has an additional part: a metal wire grid, between the heated filament and plate. The small radio signal coming from the antenna is fed into the grid, and it greatly alters the voltage flowing through the triode. […]
