The increase in Earth's rotational inertia at the tangent to the equator is calculated using the formula I = mr^2, where I is the rotational inertia, m is the mass of the object, and r is the distance from the axis of rotation.
The factors that affect Earth's rotational inertia increase at the tangent to the equator include the mass and distribution of mass within the Earth, as well as the distance from the axis of rotation.
The increase in rotational inertia at the tangent to the equator causes Earth to rotate at a slightly slower rate due to the conservation of angular momentum. This effect is known as the "tidal bulge" and is responsible for the Earth's tides.
Yes, the rotational inertia increase at the tangent to the equator can change over time due to natural processes such as plate tectonics and the redistribution of mass within the Earth's interior. However, these changes are very small and have a minimal impact on Earth's rotation.
No, the rotational inertia increase at the tangent to the equator varies for different planets depending on their mass, distribution of mass, and distance from the axis of rotation. For example, Jupiter has a much larger rotational inertia increase at its equator compared to Earth due to its larger size and faster rotation.
