While researching a topic, a student has taken the following notes:
- The Polytechnic in Gdansk, Poland, is home to a Foucault pendulum.
- The pendulum consists of a weighted ball that swings at the end of a roughly 26-meter-long cable.
- Like all Foucault pendulums, it dangles from a fixed point that ensures the swing path of the pendulum doesn’t change.
- To an observer, the swing path of a Foucault pendulum appears to change over time because Earth rotates beneath it.
- Foucault pendulums are used as a simple way to provide evidence of Earth’s rotation.
The student wants to specify the parts of a Foucault pendulum. Which choice most effectively uses relevant information from the notes to accomplish this goal?

B
Dangling from a fixed point, the Foucault pendulum at the Polytechnic consists of a cable with a weighted ball at the end.
