An elastic rubber band is stretched between two points. Will it produce any sound?
Can't be said
None of these
Unless the rubber band is plucked it will not produce any sound or if there is no medium to carry the sound to our ears, we cannot hear the sound.
A rubber band tied between two ends is stretched and then left. A sound is heard due to:
A rubber band stretches and reverts back to its original position. Bubble gum stretches, but it would not return to its original position. Is there any difference between the two processes? Discuss it with respect to plant growth (hint elasticity -reversible & plasticity-irreversible).
The diagram shows a force – extension graph for a rubber band. Consider the following statements
I. Steel has similar force extension curve
II. Rubber does not return to its original length after it is stretched
III. The rubber band will get heated if it is stretched and released
Which of these can be deduced from the graph?
