Answer:
Amy's average speed is equal to Chris's average speed.
Explanation:
Average speed is the ratio of total distance and total time interval
So here for Amy we know that
now the average speed of Amy is given as
Similarly for Chris we will have
average speed =
so correct answer is
Amy's average speed is equal to Chris's average speed.
Answer: X
Explanation:
This situation can be illustrated as a car in circular motion (image attached).
In circular motion the acceleration vector is always directed toward the center of the circumference (that's why it's called centripetal acceleration).
So, in this case the arrow labeled X is the only that points toward the center, hence it represents the car's centripetal acceleration

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.
