Even a new, minimum efficiency air conditioner or furnace can be a significant jump in efficiency. The old furnace in your basement may only be originally rated at 60% to 70% AFUE. In order to comply with national regulations, furnaces manufactured today have to be rated at a minimum of 80% AFUE.
dipole - a pair of equal and opposite electric charges or magnetic poles separated by a small distance. couple - (physics) something joined by two equal and opposite forces that act along parallel lines. electric dipole, electric doublet - a dipole with equal and opposite electric charges.
What is the magnitude of the dipole moment formed by separating a proton and an electron by 100 pm. Answers. When two electrical charges, of opposite sign and equal magnitude, are separated by a distance, a dipole is established. The size of a dipole is measured by its dipole moment . Dipole moment is measured in Debye units, which is equal to the distance between the charges multiplied by the charge. Dipolemoment 'D' = e x d where e= charge and d= distance by which charge is separated. In this case e = charge on electron = 1.6 x10^-19 C.
