How many days does it take for the moon to make a quarter orbit

27.3 days.

Explanation: The Moon actually takes 27.3 days to complete one orbit around Earth. The Moon takes 29.5 days to complete one cycle of phases.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

  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.
