4. This graph was taken from the Elastic Potential energy lab (week 3). Based on this graph, one can conclude what about the relationship between the stretch of a spring and the elastic potential energy stored by the spring? (Choose all that apply. then explain how you know) Elastic Potential Energy (J) D 5 10 15 20 25 30 stretch distance {cm} a. If you double the stretch distance. you also double the stored potential energy b. If you increase the stretch distance, the stored potential energy decreases c. If you double the stretch distance, the stored potential energy increases by more than double d. If you double the stretch distance, the stored potential energy increases by less than double
