Question

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

• the university of munich in munich, germany, is home to a foucault pendulum.
• the pendulum consists of a weighted ball that swings at the end of a roughly 20 - meter - long cable.
• like all foucault pendulums, it dangles from a fixed point that ensures the swing path of the pendulum doesnt 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 earths 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 swing path of the foucault pendulum at the university of munich appears to change over time.
b with a swing path that appears to change over time, a foucault pendulum provides evidence of earths rotation.
c the foucault pendulum at the university of munich in munich, germany, includes a cable that is roughly 20 meters long.
d dangling from a fixed point, the foucault pendulum at the university of munich consists of a cable with a weighted ball at the end.

Explanation:

The goal is to identify the parts of a Foucault pendulum. Option D combines details about the fixed - point suspension and the components (cable and weighted ball) which are key parts. Option A only mentions the swing path change (not parts). Option B focuses on the evidence of Earth's rotation (not parts). Option C only mentions the cable length (not a comprehensive description of parts).

Answer:

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