Question 4 of 22 Sir Isaac Newton was a scientist who studied the relationships between
mass, force, and motion. According to Newton, an object will accelerate at a
rate that is equal to the force acting on the object, divided by the mass of the
object. This idea can be written as a mathematical formula: acceleration =
force/mass

B. Hypothesis
C. Theory

they deliver oxygen to the blood

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

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.
