[Level 7+ Question] A 10N weight was placed on this spring and then removed. Describe and explain what then happens to the spring.
The spring will return to its original length because the weight was not great enough to stretch it beyond the spring's elastic limit.
The spring will return to its original length because the weight stretched it beyond the spring's elastic limit.
The spring will not return to its original length and will be permanently deformed. This is because the weight was not great enough to stretch it beyond the spring's elastic limit.
The spring will not return to its original length and will be permanently deformed. This is because the weight stretched it beyond the spring's elastic limit.
- 14. Multiple Choice
[Level 7+ Question] A 20N weight was placed on this spring and then removed. Describe and explain what then happens to the spring.
The spring will return to its original length because the weight was not great enough to stretch it beyond the spring's elastic limit.
The spring will return to its original length because the weight stretched it beyond the spring's elastic limit.
The spring will not return to its original length and will be permanently deformed. This is because the weight was not great enough to stretch it beyond the spring's elastic limit.
The spring will not return to its original length and will be permanently deformed. This is because the weight stretched it beyond the spring's elastic limit.
