Question

4) A scuba diver is searching for a sunken ship off the coast of NC. She is submerged in seawater 30 m below the water surface Her total volume, including her gear, is 65.0L and her total mass is 68.0 kg1.025 x 103kg/ m2. S A) Calculate the total volume of the submerged diver in cm2 and m. Volume of diver- mJ B) List an object that has a similar volume to the diver. Be creative and try to visualize volume: C) Draw a side-view perspective of the submerged diver at rest. Sketch and label all forces vectors on her: D) Calculate the magnitude of the buoyancy force due to the seawater on the diver (Fa), and the total wei ght of the diver (Fa). Fo magnitude Fa magnitude- float sink Circle one and explain your answer in 2-4 statements: E) Based on the force values in part D, the diver will:

Answer 1

A rightarrow volume of diver = 65.0 times 10^3 cm^3 = 65.0 times 10^-3 m^3 b) rightarrow A cylinder of length 180 cm and radius 10.725 cm c) rightarrow F_B = V rho g = 65 times 10^-3 times 1.025 times 10^3 times 9.8 = 652.925 N F_g = 68 times 9.8 = 666.4 N F_B magnitude = 652.925 N FG magnitude = 666.4 N E) Diver will sin k As the weight of diver = 666.4 N and Buoyancy force = F_B = 652.925 N so due to less Buoyancy force than the weight the diver will sin k
