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?

A

The Foucault pendulum at the Polytechnic in Gdansk, Poland, includes a cable that is roughly 26 meters long.

B

With a swing path that appears to change over time, a Foucault pendulum provides evidence of Earth’s rotation.

C

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

D

The swing path of the Foucault pendulum at the Polytechnic appears to change over time.
