The answer is a dense substance that is hard and incompressible.
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

if beta use some clothing or aluminium
if it is gamma use lead
The solids whose particles occur in a definite pattern are called crystaline solids.
<h3>What is a crystalline solid?</h3>
The term crystalline solid has to do with the type of solid in which the atoms that components that make up the solid are all in definite positions and occur in a regular repeating pattern.
The particles of a solid are found in fixed positions. The solids whose particles occur in a definite pattern are called crystaline solids.

Answer:
The pulling force F is 200 N
Explanation:
We note that the tension in a rope between two or three blocks is given by the relation;
Where we have;
m₁ → T₁ → m₂ → T₂ → m₃ → F
m₁ = 2 kg
m₂ = 4 kg
m₃ = 4 kg
T₂ = 120 N
Therefore, by substitution, gives;
2 kg → T₁ → 4 kg → 120 N → 4 kg → F
F = 120 N × (10 kg)/(6 kg) = 200 N
The pulling force F = 200 N.
