Question

question 10
determine which three images show an elastic force acting.

Explanation:

Elastic force is the force exerted by an object trying to return to its original shape after being stretched or compressed. In the first image, the bowstring is stretched (elastic deformation), creating elastic force. In the second image, the rope is being pulled (stretched), so elastic force acts. In the fourth image, the exercise ball is compressed, and it exerts an elastic force. The third image (skateboard - mainly involves normal force and gravity in this context, no obvious elastic deformation shown for elastic force in the key sense here), fifth image (the foam objects - if just placed, no indication of elastic force as main acting force in the way the question wants, like no stretching/compressing shown as key), sixth image (person on board - more about balance and normal force, no key elastic deformation for elastic force as per question's intent).

Answer:

First image (archer with bow), Second image (dog with rope), Fourth image (person on exercise ball)
