If you took a 20 foot tree and hammered a spike into 3 feet above the ground how high would that spike be 30 years later when the tree is 100 feet tall ? why?

im not intirely sure but i think the anwser is d relative humidity

radon is correct hope this

cuz some people don't have enough food. that's why we need more ppl to donate food to the hungry.

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.
