27. suppose two stars are located in region a of the h-r diagram shown in the figure below. star x appears much dimmer than star y as see from earth. which star can be inferred to be nearer to earth, and how do you know?

it becomes positively charged by charging it

  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.
