Final answer:
In a Hooke's law test on a spring, weight measurements were obtained. Hooke's law can be applied to weight measurements as weight is a type of force measured in newtons. Whether the spring followed Hooke's law or if the weight increments were constant depends on the data.
Step-by-step explanation:
In a Hooke's law test on a spring, weight measurements were obtained at different values. Let's discuss each option:
- (a) Hooke's law applies to weight measurements: Since weight is a force, Hooke's law can be applied to weight measurements. So this statement is correct.
- (b) Weight was used instead of force in the test: This statement is incorrect. Weight is a type of force that is measured in newtons. So weight can be used as a measure of force.
- (c) The spring followed Hooke's law: Hooke's law states that the force required to stretch or compress a spring is proportional to the displacement of the spring. If the results obtained followed this pattern, then the spring can be said to follow Hooke's law. So, this statement could be correct depending on the data.
- (d) The weight increments were constant: Since weight is a measure of force, the weight increments would also represent force increments. If the increments remain constant, then the force increments are also constant. So, this statement could be correct depending on the data.
