The mass of the star proxima centauri is 12% of the mass of the sun. what would be the likely impact on the motion of earth if the sun were replaced by proxima centauri? a day would be shorter because the gravity experienced by earth would be stronger. a day would be shorter because the gravity experienced by earth would be weaker. a year on earth would be longer because earth would move relatively faster in its orbit. a year on earth would be longer because earth would move relatively more slowly in its orbit.

  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.
