(b) The diagram shows the energy transformations produced by a TV.

(1)
Which are the useful energy outputs?
(1)
(ii)
Use the information in the diagram to calculate the efficiency of the TV.
Write down the equation you use, and then show clearly how you work out
your answer.

iii) what eventually happenes to the useful energy transferred by the tv?

  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.

that the claims meet official rules.

don't misinterpret the claims
