Step 1
Show that y is not inversely proportional to M.
Answer
To show that y is not inversely proportional to M, we can analyze the data provided in Figure 10. The relationship between y and M can be examined by calculating the ratio of y to M for different points.
-
Collect Data Points: Take the data points from Figure 10 for M (mass in kg) and y (distance in mm).
-
Calculating Ratios: For each data point, calculate the values of y/M. If y were inversely proportional to M, we would expect this ratio to be constant.
-
Evaluate Results: Plot the calculated ratios and observe if they remain consistent. If there is a variation, it proves that y is not inversely proportional to M.
-
Conclusion: Since the ratios are not constant, we can conclude that the relationship between y and M does not support an inverse proportionality.
