If an object was observed to orbit the Sun once every half of a year, what would be this object's average distance from the Sun according to Kepler's third law? A. 0.63 au

B. 0.25 au

C. 0.79 au

D. 0.71 au

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

b.
