Ploughs were traditionally drawn by working animals such as horses or cattle, but in modern times are drawn by tractors.
Nonpolar molecule. Definition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.However, the polar bonds in nonpolar molecules are arranged symmetrically causing dipoles to cancel out each other. As a result, nonpolar molecules have no net dipole.efinition. noun, plural: nonpolar molecules. A molecule with nonpolar bonds or with polar bonds but arranged symmetrically. Supplement. Polar bonds may occur in both polar and nonpolar molecules.
The Difference between polar and nonpolar molecules as follows. Polar molecules. A molecule in which there is a little division of charge in the chemical bonds, so that one part of the molecule has a small positive charge and the other has negative charge i.e. dipole. H2O is a good example of a polar molecule.he Difference between polar and nonpolar molecules as follows. Polar molecules.
