Which item in the photo is a good thermal insulator, and why? A. The cut vegetables, because they contain a lot of water
B. Human skin, because it is made up mostly of water
C. The plastic handle, because its electrons don't move freely
D. The metal pan, because its electrons move quite freely

  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.
