An asteroid is discovered in a nearly circular orbit around the Sun, with an orbital radius that is 2.51 times Earth's. What is the asteroid's orbital period , its "year," in terms of Earth years?

300,000,000,000,000,000,000,000,000,000,000

Explanation:

c

explanation:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
