Question
Plz give a short answer to these three questions 1- The spring is characterized by the spring constant, moreover, the force per displacement. How is the slope related to the spring constant ? 2- How is the last column in the Table 4 related to the spring constant ? What if we average the values of last column in Table 4? Explain your answers. What is the meaning y-intercept ? Do you understand why it is always better use y=mx+b as opposed to y=mx in performing a curve fit ? Plz just give me a small answer to each one

Part 2: Graphical Analysis of Data
For many spring-mass systems, the amount a spring stretches when it suspends a mass is proportional to the
amount of mass supported by the spring. This is called Hooke's law. We will test that here.
