1. Based on the results of Experiment 3, the pH of a 2.5% formic acid solution at 25°C would most likely have been closest to which of the following?
2. Based on the apparatus diagram, Figure 1, and Figure 2, each of the 2 beams tested must have been longer than:
3. Consider the difference between d for a beam in the H configuration and d for that beam in the I configuration. As L was increased, the absolute value of this difference:
4. For the studies to be performed as described, which of the following criteria must have been satisfied during any given trial?
5. In how many studies was the concrete beam tested, and in how many studies, if any, was only the concrete beam tested?
6. Suppose that in Study 3 the 2 beams had been tested in the H configuration. How would the results most likely have compared with the data shown in Figure 3?
7. Can it be determined on the basis of Study 2 whether the maximum deflection of the steel beam depended on the strength of the applied force?
8. Based on Student 3’s predictions, which of the variables listed below does NOT affect f?
9. According to the predictions of Student 1 and Student 2, respectively, as cube mass increases, does the cube’s average speed during a cycle increase or decrease?
10. Based on Student 2’s predictions, which of the changes listed below would cause f to decrease?
11. Based on Student 1’s predictions, as k increases, the cube’s average kinetic energy will:
12. Suppose that M = 1 kg for Cube R and that M = 2 kg for Cube S. Based on Student 3’s predictions, for given values of k and A, the average acceleration will be greater for which cube?
13. Consider 2 springs, Spring X and Spring Y. Spring X has a smaller k than does Spring Y. Student 1 would probably agree that the cube will take a longer time to complete a cycle if it is attached to which spring?
14. Based on the information given, what total distance will the cube travel during 1 complete cycle?
