Using hooke's law, what happens when the displacement is tripled?
a: the restoring force is tripled
b: the restoring force is reduced by one third
c: the amplitude is reduced by one third
d: the spring constant is tripled

c

Nothing, the only way to change the mass it to add or remove material, a change in volume does neither.

If the substance is uniform, then the mass also triples.

Explanation:

for points guys

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.
