Detailed explanation-1: -When a rubber ball is squeezed, the curly rubber molecules stretch out, but then quickly return to their curlier shape which makes the ball bounce.

Detailed explanation-2: -A rubber ball changes shape when you use force to squeeze it, but it returns to its original shape when you stop squeezing. Materials that do this have elasticity. They are made up of particles called molecules that can stretch apart.

Detailed explanation-3: -Complete answer: When we press a rubber ball between our hands, balanced forces act on it and hence its shape changes. This is because two equal and opposite forces (balanced forces) are applied by our hands. So, the resultant of this force does not move the object, this is a balanced force.

Detailed explanation-4: -The effect of force is the lemon juice being expelled by squeezing, (b) The hand is the agent, toothpaste tube is object and the coming out of the paste from toothpaste tube is the effect of force.
