Starting at the Prime Meridian and heading eastwards, the Tropic of Capricorn passes through 10 countries: The following cities and landmarks are either located near the Tropic of Capricorn, or the tropic passes through them. As the major portion of earth's land is located in the Northern Hemisphere there are only four countries entirely south of the Tropic of Capricorn (there are 74 countries entirely north of the Tropic of Cancer): Length of the Tropic on 11 June 2015, at 23°26′14″S is . Tropic of Capricorn The Tropic of Capricorn (or the Southern Tropic) is the circle
Degrees of freedom (physics and chemistry) for 3 degrees of freedom. In addition, the molecule has two rotational degrees of motion and one vibrational mode. The rotations occur around the two axes perpendicular to the line between the two atoms. The rotation around the atom–atom bond is not a physical rotation. This yields, for a diatomic molecule, a decomposition of: For a general, non-linear molecule, all 3 rotational degrees of freedom are considered, resulting in the decomposition: which means that an -atom molecule has vibrational degrees of freedom for . In special cases, such as adsorbed large molecules, the rotational degrees of freedom can be limited
