While researching a topic, a student has taken the following notes:

• The University of Oslo in Oslo, Norway, is home to a Foucault pendulum.
• The pendulum consists of a weighted ball that swings at the end of a roughly 14-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.

Which choice most effectively uses relevant information from the notes to specify the length of the Foucault pendulum’s cable?

A

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

B

The Foucault pendulum at the University of Oslo consists of a weighted ball and a cable.

C

Although the swing path of a Foucault pendulum doesn’t actually change, it appears to change due to Earth rotating beneath the pendulum.

D

The Foucault pendulum at the University of Oslo in Oslo, Norway, includes a cable that is roughly 14 meters long.
