Aparticular 60 hz ac induction motor requires some phase delay to operate properly. the real power is 60 kw under a full load that includes real work, heat, vibration and noise. the motor was designed to operate with an 85% power factor (pf) when fully loaded, because some phase difference between voltage and current is necessary to establish the magnetic field in the motor. compute the motor's effective resistance r (with units) given the real power consumed at 240v ac is 60 kw a) b) to produce a capacitive reactance x-1 ohm, what capacitance would be needed at c) 60 hz? (4 pt) compute the capacitive reactance x that must be added in order to increase the power factor to 100% for 240 v and give units.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
