The photograph below shows a Foucault pendulum at a museum. The pendulum knocks over pins in a regular pattern as it swings back and forth.
This pendulum movement, and the pattern of
knocked-over pins, is evidence of Earth’s
(1) nearly spherical shape
(2) gravitational attraction to the Sun
(3) rotation on its axis
(4) nearly circular orbit around the Sun
