Question

how can you tell if an object has elastic properties?

if two people pull on it in opposite directions, it stretches and remains in a new shape

if two people pull on it in opposite directions, it falls apart

if two people pull on it, it maintains its original size and shape

if two people pull on it in opposite directions, it stretches. then when they let it go, it returns to its original size and shape

Explanation:

Elasticity is the property of a material to return to its original shape after deformation. When an object is stretched (deformed) by pulling and then returns to its original size and shape (undoes the deformation) when released, it shows elastic properties.

• Option 1: Stretching and remaining in a new shape shows plasticity (non - elastic).
• Option 2: Falling apart shows brittleness (non - elastic).
• Option 3: Maintaining original size and shape when pulled shows rigidity (non - elastic as there is no deformation).
• Option 4: Stretching (deformation) and then returning to original shape (elastic recovery) shows elastic properties.

Answer:

If two people pull on it in opposite directions, it stretches. Then when they let it go, it returns to its original size and shape.
