Above is a drawing of three strings hanging from a bar. The three strings are made from identical materials and have weights attached to their ends. String 1 and String 3 are the same length. String 2 is shorter. A 10 unit weight is
attached to the end of String 1. A 10 unit weight is also attached to the end of String 2. A5 unit weight is attached to
the end of the String 3. The strings (and attached weights) can be swung back and forth, and the time it takes to
make a swing can be timed.
Use the figure and description above to answer the next two questions.
Which of the following statements would be an appropriate hypothesis for an experiment that only uses strings 1 and
2?
The time it takes to swing back and forth is different on the moon than on Earth.
The time it takes to swing back and forth is different for different string materials.
The length of the string affects the time it takes to swing back and forth
The weight on the string affects the time it takes to swing back and forth.
