No, only for elastic materials and only for forces which are within the material's elasticity.
No, not every material is valid for Hooke's Law. Hooke's Law is specifically valid for linearly elastic materials, which exhibit a linear relationship between stress and strain. Materials that do not exhibit linear elasticity, such as plastics or rubber, do not follow Hooke's Law.
Materials such as metals (e.g. steel, aluminum), rubber, and certain plastics typically obey Hooke's Law of elasticity within their linear elastic range. This means they exhibit a linear relationship between stress and strain when subjected to small deformations.
Hooke's law is valid for many materials within their elastic limit, regardless of the force applied. However, for extremely large forces, materials may deform plastically or reach their ultimate strength, at which point Hooke's law may no longer accurately describe the material's behavior.
Not all conductors obey Ohm's Law. There are certain materials, like semiconductors and diodes, that do not follow Ohm's Law due to their nonlinear behavior. An example of a conductor that obeys Ohm's Law is a resistor, where the current through it is directly proportional to the voltage applied.
The Law of Conservation of Energy is valid in all isolated systems where there is no external energy being added or lost. It is a fundamental principle in physics that states the total energy within a closed system remains constant over time.
all of them
Its all to do with Hookes law................

Hello jack cena
Hooke's law of Elasticity.
Materials such as metals (e.g. steel, aluminum), rubber, and certain plastics typically obey Hooke's Law of elasticity within their linear elastic range. This means they exhibit a linear relationship between stress and strain when subjected to small deformations.
Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it.
Hooke's Law relates to the elasticity of elastic objects, such as metal springs, and how they stretch in proportion to the force that acts on them.
No, by definition Hooke's law relates to linear elastic only; when outside the elastic region it does not apply.
It's valid.
Yes, in theory. But it is only valid up to a certain point of stress, after which the molecular bonds starts to break down. In reality, some materials are so difficult to stretch (so brittle) that it is almost impossible to apply Hooke's law to them. (Our school teacher use to say: dunk a biscuit into tea and then try to stretch it)
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
