- 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 information from the given sentences to specify the length of the Foucault pendulum's cable?
