Restate the definition of efficiency assuming that the heating properties of a light bulb are more important than the illumination.

In topics related to power, work or energy, the definition of efficiency is described as:

Efficiency = useful intended output / total input 

Therefore with this definition, we restate that:

Efficiency is energy transferred to light divided by the electrical energy consumed (input).

  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.

the maxium height is 34m/s
