Which of the following describes the effect of a convex mirror on light rays?
a. it reflects light rays inward.
b. it reflects light rays outward.
c. it has no effect on light rays.
d. it has the same effect on light rays as a concave mirror.

unlike poles attract

  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.
