The questions from this lot which could be tested in a scientific manner would be "what causes some people to be color-blind"
and
"what are the best shoes to wear when exercising"
Both of these questions can be tested in a scientific way through an experiment.
Answer: Is permanently deformed.
Explanation (see the diagram shown below).
For most structural materials:
(a) The deformation in the elastic zone is recoverable, and the material returns
to its original shape when the load (or stress) is removed.
(b) A permanent set (non-recoverable deformation) occurs when the material
is sressed beyond the elastic zone, that is, in the plastic zone.
The equation that shows the relationship between X₁ and X₂ in the springs is X₁ = 4X₂.
<h3>How to compute the equation?</h3>
From the complete question, for case I, the two springs stretch up to the distance of X₁. Therefore, f = mg = kx₁.
For case 2, f = mg = kx₂.
Therefore, we'll equate the equations. This will be:
Kx₁ = Kx₂
(K/2)x₁ = (2k)x₂
K(x₁/2) = k(2x₂)
X₁/2 = 2x₂
X1 = 2 × 2x₂
X₁ = 4X₂.
In conclusion, X₁ = 4X₂.
