3. The graph below shows force as a function of stretch (AL) for an object. Note that parts (a) and (b), I am not asking for numbers or calculations; the questions are asking you to explain how you could determine the relevant quantities. 1500 F (N) 1000 500 0 AL (cm) 01 2 3 4 5 2021 Pearson Education, Inc. (a) If this graph shows data for a spring, briefly describe how you could determine the spring constant. (b) If instead, this graph shows data for a wire of length L and cross sectional area A, briefly describe how you could determine the Young's modulus for the wire. 3.
