Some circular region with radius = 12 km centered at the equator. the air within this circular region is initially motionless with respect to the earth. the circular region is moved to the north pole along an isobaric surface in order to preserve its area. find the mean tangential velocity at this radius at the north pole.

  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.
