A750-w motor might also be rated as a

Do u mean the units.. if yes...watt is the unit of power...
Power = workdone÷ time =(force× diatance) ÷ time =mad÷t
Now unit of that is ( kg×ms^-2×m ) ÷ s

So u obtained kg m^2 s^-3
..750w can be also rated ad 750 Kgm^2s^-3

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 -
