The following are the questions in which a testable hypothesis be developed:
- Does the width of a rubber band affect how far it will stretch?
- How does the thickness of a material affect insulation?
- Do all objects fall to the ground at the same speed?
Thus, the correct options are 1, 2, and 4.
<h3>What is Hypothesis?</h3>
A hypothesis may be defined as a proclamation or group of information which is mandated to be experimented with using an investigation procedure.
The width of the rubber is a variable quantity that can be measured, observed, and recorded in the conclusion. Similarly, the thickness of the material is also varied with respect to certain terms and conditions, and hence can be measured observed, and recorded in the experimental data.
Therefore, it is well described above.
