In a period of 1.5 s, 5.0 1023 nitrogen molecules strike a wall of area 8.8 cm2. if the molecules move at 250 m/s and strike the wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (the mass of one n2 molecule is 4.68 10-26 kg.)

  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.
