Calculate the efficiency for each machine, then answer the question. Machine A has an input work of 1,000 J and an output work of 250 J.

Machine B has an input work of 500 J and an output work of 350 J.

Machine C has an input work of 200 J and an output work of 150 J.

answer: a. same unit

explanation:

  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.
