Which does Kepler’s second law state about planetary motion?(1 point) Responses The planet travels along an elliptical orbit. The planet travels along an elliptical orbit. The square of the orbital period is directly proportional to the cube of the semi-major axis. The square of the orbital period is directly proportional to the cube of the semi-major axis. A line between the planet and the sun covers equal areas in equal times. A line between the planet and the sun covers equal areas in equal times. Planets move at the same speed at all points along their orbit.
A line between the planet and the sun covers equal areas in equal times.
How did Kepler develop his second law of motion?(1 point) Responses He compared data of planetary motion at different times along orbits. He compared data of planetary motion at different times along orbits. He invented a telescope that was strong enough to view all planets of the solar system along their orbits. He invented a telescope that was strong enough to view all planets of the solar system along their orbits. He used a telescope to carefully follow and time the orbital motion of Mars. He used a telescope to carefully follow and time the orbital motion of Mars. He made accurate measurements of the positions of all the planets over many years.
He used a telescope to carefully follow and time the orbital motion of Mars.
Kepler's second law states that "A line between the planet and the sun covers equal areas in equal times."
The correct statement regarding Kepler's second law of planetary motion is: "A line between the planet and the sun covers equal areas in equal times."
