**Deformation of a spring (questions 28-30) **
Open-ended question (equals three questions, total points).
A spring has one end attached to a wall and the other free. The free head is subjected to forces of varying intensity in the direction of the axis, which deform the spring. The relationship between the length of the spring and the force applied is described in the graph. I’m going to start with this.

By referring to the chart, answer the questions.
**A) ** What is the resting length of the spring? Does the spring follow Hooke’s law? **C) ** Calculate the value of the elastic constant. **D) ** Is the force exerted on the spring greater under the conditions described in point C or point D of the chart? - Explain that. **E) ** In the stretch between A and B the length remains constant. What’s wrong with the spring? **F) ** An identical second (mole 2) is attached to the first spring (mole 1) in series. Applying a force of N, what is the total length of the two-spring system?G) The two identical springs connected in series shall be applied such a force that the total length of the system is dm. What is the intensity of the force applied?
