Here are the solutions to the questions: Question 11: A student investigates the stretching of a spring. Calculate the extension e of the spring using the equation e = (l - l0) when L = 5.00 N. Record this value of e in Table 1. Step 1: Identify the unstretched length (l_0) from Table 1. From Table 1, when L = 0.00 N, the length l = 2.1 cm. So, l_0 = 2.1 cm. Step 2: Identify the stretched length (l) for L = 5.00 N from Table 1. From Table 1, when L = 5.00 N, the length l = 23.7 cm. Step 3: Calculate the extension (e). e = l - l_0 e = 23.7 cm - 2.1 cm e = 21.6 cm The value to be recorded in Table 1 for L = 5.00 N is 21.6 cm. The completed Table 1 is: | L/N | l/cm | e/cm | | :-- | :--- | :--- | | 0.00 | 2.1 | 0.0 | | 1.00 | 6.0 | 3.9 | | 2.00 | 10.6 | 8.5 | | 3.00 | 14.9 | 12.8 | | 4.00 | 19.3 | 17.2 | | 5.00 | 23.7 | 21.6 | c) Plot a graph of L (N) (y-axis) against e (cm) (x-axis). Start both axes at the origin (0, 0). Draw the best-fit line. To plot the graph: 1. Draw Axes: Draw two perpendicular axes. Label the vertical axis "Load L (N)" and the horizontal axis "Extension e (cm)". 2. Choose Scale: Select appropriate scales for both axes. For the x-axis (Extension e): The values range from 0.0 cm to 21.6 cm. A suitable scale would be 1 cm representing 1 cm of extension (or 2 cm representing 1 cm of extension for a larger graph). For the y-axis (Load L): The values range from 0.00 N to 5.00 N. A suitable scale would be 2 cm representing 1 N of load. 3. Origin: Ensure both axes start at the origin (0,0). 4. Plot Points: Plot the following data points (e, L) from the completed Table 1: (0.
