during the morning walk a boy Run along the side of a square field if side is hundred metre long what is the maximum magnitude of displacement of the boy in any time interval​

whichever one it is, it's definitely not one that you included on the list you provided.

does anyone know or what?

radiation

explanation:

heat is transmitted by radiation

  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.
