Answer: C
X = Displacement of the spring
Hooke's law: It states that the applied force F is proportional to the displacement of spring .
F ∝ x
Where, x = displacement of spring in meters
F = force, measured in Newtons
In another words The force F is equal to the constant K times the disparagement.
F = k.x
Where k is constant and it depends on elastic material.
Spring has restorative force.
If the spring moves in opposite direction then,
F = - k.x
A negative sign indicates that the spring resists and force is to the left. The compression of the spring is greater than the restoring force.
Example: A mass 'm' stretches a spring at a displacement x.
Your mass will never change despite if you go to Jupiter, Uranus, Mars, Earth, or any planet.
Answer:
The answer to your question is Nonmetals
Explanation:
Nonmetals they are bad conductors of heat and electricity except graphite.
Metalloids they are less conductors of electricity than metals.
Noble gases they conduct electricity.
Halogens they are not metals and do not conduct electricity.
From this information, we conclude that Oxygen and Selenium are nonmetals.
The force will be 4 times smaller.
