Question
### Explanation of the Graph The graph represents a scatter plot showcasing the relationship between an external force (\( F_{ext} \)) and another variable labeled \( x \). The data points are shown as red circles with black outlines, plotted along the graph. These points suggest a positive correlation between the two variables. A blue dashed line is drawn through the data points, indicating the "Approximate best fit line." This line represents a trend or linear approximation of the data, showing the general direction of the relationship between \( F_{ext} \) and \( x \). ### Quiz Question Below the graph, there is a multiple-choice question that asks: - What does the variable \( x \) represent in the context of this graph? Here are the answer options provided: 1. The spring constant "k" 2. The force being applied to the spring 3. How much the spring has stretched 4. The potential energy of the spring Users must select the option that correctly describes the variable \( x \) in relation to the graph and the concept it is illustrating.

Suppose you apply a variety of forces to a spring, and for every force (\( F_{ext} \)) you measure the corresponding amount that spring stretches from its equilibrium position (\( x \)). If you were to create a trend-line (or a best-fit line) for this data as shown in the image below, what would the slope of this trend-line represent physically? Note, in the figure below, the red circles are the data, and the blue-dashed line is the best-fit or trend-line for that data. ### Diagram Explanation The diagram depicts a graph with: - The vertical axis labeled \( F_{ext} \) representing the external force applied to the spring. - The horizontal axis labeled \( x \) representing the displacement of the spring from its equilibrium position. - Red circles plotted on the graph indicating measured data points of force versus displacement. - A blue dashed line indicating the best-fit line through the data points. - A box labeled "Approximate best fit line" highlighting the best-fit line. The slope of this best-fit line physically represents the spring constant, a measure of the stiffness of the spring according to Hooke's Law, which states that the force exerted by a spring is directly proportional to its displacement.
