Assuming you want a true or false answer, this is true.
The main job of these systems is to break down food and for it to exit the body after taking out of it what is necessary such as nutrients
Upthrust = loss in weight = 0.82 - 0.059 = 0.761 Kg
upthrust = weight of the displaced fluid = 0.79*Vg where Vg is the volume of the piece of wood
Therefore:
0.761 = 0.79 Vg
Vg = 0.96329
Density of wood (sg of wood) = mass / volume
density of wood = 0.82 / 0.96329 = 0.85
Answer:
76,6 kg
Explanation:
A kg it's equal to 1x10^3 grams
A Gigagrams it's equal to 1x10^9 grams
Knowing this, a kg it's equal to 1x10^6 gigagrams
