Question: Two workers expend the same physiological energy during the same time doing different tasks. Joe has a mass of 1 0 0 kg . Sam

Two workers expend the same physiological energy during the same time doing different tasks. Joe has a mass of 100 kg. Sam has a mass of 75 kg. Which of the statements below best describes the relative physiological intensities of these workers?
Joe has the greater intensity because he used more power per unit mass.
Both had equal intensities because they both used the same power.
Sam has the greater intensity because he used more power per unit mass.
The relative intensity cannot be determined because you cannot compare the intensities of different tasks.
