Question

Yosef is playing with different kinds of rubber bands. Some are very narrow, and some are quite wide. Yosef is curious about the rubber bands and develops this scientific question: Does the width of a rubber band affect how easily it can be stretched? He decides to develop a hypothesis to test this scientific question. What could Yosef’s hypothesis be?

Answer 1

Answer:

Yosef hypothesis could be stretching of rubber band depends on rubber band's width. It is difficult to stretch a wider rubber band in comparison to a narrow band.  

Explanation:

Width of rubber band affect how easily it can be stretched. It is found that it is difficult to to stretch a wider rubber band in comparison to a narrow band because when rubber band is narrow less molecules will be there along its width and hence less restoring force will be there so rubber can be easily stretched. On the other hand when the rubber band is wider it means more molecules  are there along its width and hence more restoring force will be there while stretching so it will be difficult to stretch a wider rubber band.

Answer 2

Answer:

If the width of a rubber band is increased, then it will be more difficult to stretch because more force will be needed to stretch it.
