Answer:
The correct answer is : Wair ÷ (Wair-Ww)
Step-by-step explanation:
The density of human body can be calculated by the density of the individual in the air (Wair) and density in submerged in water (Ww). The density of human body is proportional to the ratio of the mass upon volume.
The mass of an individual is easily find by the density in air and volume can be calculate by the density in air minus density in water.
So, the correct answer is : Wair/(Wair-Ww).
