Does the calculation of this table support Kepler's second law? Explain why or why not.

Answer 1

Kepler's 2nd law states that " A planet moves in its ellipse sweeps out equal areas in equal times with sun at one of it's focus" . The figure above shows a planet moving in the ellipse with sun at one of its focus, f1, and shaded portions are the areas swept by the planet at two same time intervals.

In the calculations in the above table makes at same interval of time then the table supports Kepler's second law since the calculated area of triangle shown in the table is approximately equal for each time interval and which is the statement of Kepler's second law.
