Question

A line between a planet and the sun sweeps out two equal areas at different places as it moves along its orbit. Which factor remains constant as this happens?(1 point) the planet’s speed as it sweeps out the areas the time required to sweep out the areas the distance from the sun to the planet while it sweeps out the areas the distance the planet moves along its orbit while it sweeps out the area

Answer 1

Answer:

Kepler's second law states that a planet moves in its ellipse so that the line between it and the Sun placed at a focus sweeps out equal areas in equal times.

Explanation:

Answer 2

The factor that remains constant as the line sweeps out two equal areas ; The time required to sweep out the areas ( B )

According Kepler's law the angular momentum of a planet moving in its elliptical orbit round the sun is constant while the distance from the sun to the planet keeps changing. also the planets' speed as it sweeps out the areas will continue to change because the planet is moving on an elliptical orbit .

The time required to sweep out the areas is constant because the line that joins the sun to the planet sweeps out the two equal areas as the planet orbits round the sun at equal times

Hence we can conclude that The factor that remains constant as the line sweeps out two equal areas  The time required to sweep out the areas.
