Answer

Brief Explanations:

The question is about the relationship between string - length of a pendulum and its oscillation frequency in a given time. Constants/control variables could include the mass of the pendulum bob, the starting angle of the pendulum, and the gravitational acceleration (assuming the experiment is done in one place). A hypothesis could be that as the length of the string increases, the number of times the pendulum swings back and forth in 10 seconds decreases because a longer - length pendulum has a longer period of oscillation.

Answer:

Constants/Control Variables: Mass of pendulum bob, starting angle, gravitational acceleration. Hypothesis/Prediction: As the length of the string increases, the number of swings in 10 seconds decreases.
