Answer:
The force will increase in proportion to the mass of the objects
Explanation:
The acceleration due to gravity is always the same. It is expressed in meters per second squared or m/s². The figure of 9.81 m/s² is an average value that was taken after calculating the acceleration under different surfaces. In fact, the acceleration differs depending on the shape of the part of the earth in relation to the earth's magnetic field and force.
Thus, if one washer was 20 kg, the acceleration being 9.81 m/s² the weight will be:
F = ma
= 
If there are there washers, the weight will be:
F = 3 * 20 * 9.81
= 588.6 N

Full Question:
Why do we use other bonding theories in addition to the lewis model?
a) Lewis model is not suitable for all molecules or ions. b) Lewis model cannot predict all of the properties of a molecule or ion. c) Lewis model is too complicated.
Answer:
b) Lewis model cannot predict all of the properties of a molecule or ion.
Explanation:
Lewis structures, also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.
Lweis model does not explain the geometry of molecules, how the bonds form, or how the electrons are shared between the atoms hence the need to use other bonding theories.
