Question

Kepler's second law tells us that planets sweep out equalareas in equal times. If you compare the amount of area per timeswept by Earth with the one of Jupiter, you would conclude: They sweepdifferent areas per time. Earth sweeps alarger area per time because it has much less mass thanJupiter. Jupiter sweeps alarger area per time because it has much more mass thanEarth. They sweep thesame area per time. Kepler's second law tells us that planets sweep out equalareas in equal times.

Earth sweeps alarger area per time because it has much less mass thanJupiter. Jupiter sweeps alarger area per time because it has much more mass thanEarth. They sweep thesame area per time. They sweepdifferent areas per time. Earth sweeps alarger area per time because it has much less mass thanJupiter. Jupiter sweeps alarger area per time because it has much more mass thanEarth. They sweep thesame area per time.

Explanation / Answer

. That law applies only when comparing the motion of single planet at different points in its orbit. It does not applyto comparing different planets. Earth and Jupiter "sweep out"different areas per time They sweep different areas pertime. Earth sweeps alarger area per time because it has much less mass thanJupiter. Jupiter sweeps alarger area per time because it has much more mass thanEarth. They sweep thesame area per time.
