## Step 1The problem is asking us to identify the law that states that each planet revolves around the sun in such a way that an imaginary line connecting it to the sun sweeps out equal areas in equal intervals of time. This is a description of Kepler's second law of planetary motion.## Step 2Let's briefly review the other options as well:- Kepler's first law of planetary motion states that the orbit of every planet is an ellipse with the Sun at one of the two foci.- Kepler's third law of planetary motion states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.- The law of universal gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.## Step 3Based on the above explanations, it is clear that the correct answer is Kepler's second law of planetary motion.
