Alexandra and Sal are conducting an experiment to study pendulums. In their first experiment, Alexandra and Sal changed the length of the pendulum and measured its period. In their second experiment, the mass of the pendulum bob was varied, and period was measured. 1. Before running the experiments, Sal hypothesized that increasing the mass of the pendulum would result in an increase in the pendulum's period. Was Sal correct? A. Sal was correct because mass is the only variable that will affect the period of the pendulum. B. Sal was correct because mass and length both affect the period of the pendulum. C. Sal was incorrect because only the length of the pendulum will affect the period of the pendulum. D. Sal was incorrect because only the initial angle will affect the period of the pendulum.

Question
Use the following prompt for questions 1-2.
Alexandra and Sal are conducting an experiment to study pendulums. In their first experiment, Alexandra and
Sal changed the length of the pendulum and measured its period. In their second experiment, the mass of the
pendulum bob was varied, and period was measured.
1. Before running the experiments, Sal hypothesized that increasing the mass of the pendulum would
result in an increase in the pendulum's period. Was Sal correct?
A. Sal was correct because mass is the only variable that will affect the period of the pendulum.
B. Sal was correct because mass and length both affect the period of the pendulum.
C. Sal was incorrect because only the length of the pendulum will affect the period of the
pendulum.
D. Sal was incorrect because only the initial angle will affect the period of the pendulum.
