An addition of 400 J of thermal energy and a loss of 550 J of kinetic energy O C. An addition of 200 J of thermal energy and a loss of 550 J of thermal energy D. An addition of 500 J of kinetic energy and a loss of 450 J of thermal energy

power out to power in less than 100%

no. dot product   =0 when vecs at right angles

  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.
