(II) On dry land, an athlete weighs 70.2 kg. The sameathlete, when submerged in a swimming pool and hangingfrom a scale, has an "apparent weight" of 3.4 kg. UsingExample 10-8 as a guide, (a) find the total volume V of thesubmerged athlete. (b) Assume that when submerged, theathlete's body contains a residual volume VR = 1.3 × 10-³ m³of air (mainly in the lungs). Taking V – Vg to be theactual volume of the athlete's body, find the body's specificgravity, SG. (c) What is the athlete's percent body fatassuming it is given by the formula (495/SG) – 450?|lift
