Explanation:
Detailed explanation-1: -L(t) dt, where L(t) = ||L(t)||, i.e. L(t) is the magnitude of the angular momentum vector. Corollary [Kepler/Newton]. If an object moving about the origin in the plane is acted on by (only) a central force, then the radius vector sweeps out equal areas in equal times.
Detailed explanation-2: -The law of periods/Third law: The Square of the period of revolution (T) of any planet around the sun is directly proportional to the cube of the semi-major axis of the orbit (r). Hence T2 ∝ r3.
Detailed explanation-3: -Kepler’s law of periods states that: The cube of the mean distance of a planet from the sun is directly proportional to the square of time it takes to move around the sun. Was this answer helpful?
