The spring with the largest spring constant would be Spring B.
To determine if an object has elastic properties, you can perform a simple experiment involving two people pulling on it in opposite directions. Here's how you can apply each of the given responses to check for elasticity:
1. If two people pull on the object and it maintains its original size and shape, this indicates that the object has elastic properties. Elastic materials are able to deform temporarily when a force is applied but can return to their original shape once the force is removed.
2. If two people pull on the object and it falls apart, this suggests that the object is not elastic. It may be fragile or have weak structural integrity, causing it to break under tension.
3. If two people pull on the object and it stretches, but does not return to its original size and shape after they let it go, then the object does not possess elastic properties. This could imply that the material is either plastic or exhibits plastic deformation, meaning it permanently retains the new shape after being stretched.
4. If two people pull on the object and it stretches, but returns to its original size and shape once they release it, this confirms the presence of elastic properties. Elastic materials can be deformed under stress but recover their original form due to the forces of molecular attraction within the material.
5. If two people pull on the object and it stretches, yet remains in a new shape even after they release it, this indicates a lack of elastic properties. The object might display permanent deformation or undergo plastic deformation, wherein the stretched shape becomes its new equilibrium configuration.
By conducting these experiments, one can assess an object's ability to retain its original size and shape when subjected to opposing forces, thereby determining whether it possesses elastic properties.
