Gravitational Force between two Light Objects - Let us now calculate the force of gravitation existing between two unit masses separated by a unit distance. m 1 = 1 kg m 2 = 1 kg d = 1m G = 6.6734 x 10 - 1 1 Nm 2 /kg 2 This is a very weak force. To find Force existing between two objects of masses ..

The scale in which the relative atomic masses of different atoms are expressed is called atomic mass unit scale. Atomic masses are not expressed as whole numbers because natural elements are mixtures of two or more isotopes. The atomic weight of chlorine is 35.43 amu. Chlorine exists as two isot..
