Cantidad de calor necesaria para cambiar la temperatura de 1 kg de sustancia 1 °C

0.11 m/s and 0.28 m/s should be correct

increase masses, decrease separation

  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.
