Mrs. Moran and Mr. Moran decided to move the cabinet in their dining room. Mrs. Moran stood on one side, and Mr. Moran stood on the other. They each pushed
with 30 N of force. What was the net force on the cabinet?

60N

Explanation:

The net force on the cabinet is 60N.

 Net force is that single force that will act like all other forces on a body. The direction of the force and magnitude is very important when resolving forces.

  Force applied by Mrs. Moran  = 30N

  Force applied by Mr. Moran = 30N

                Since they each stood on both sides and pushed, the net force will be 30N + 30N  = 60N

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
