A younger student is trying to push a heavy box down the hallway. They are pushing as hard as they can, but haven’t moved the box. Have they done any work? Why or why not?

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
