Which of these statements is always true? question 12 options: if an object is moving, a net force is acting on it. a moving object in equilibrium can change its direction but not its speed. an object in equilibrium must not be in motion. a moving object in equilibrium continues at a constant velocity.

c is the correct answer hope this !

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.
