A large 5-m long Tiger Shark caught off the coast of Florida was found to weigh 15000 N (on the boat). Its humongous liver was removed and found to weigh 3500 N! A subsequent buoyancy test found that the oil-filled liver has an average density of 0.92 kg/L.
a) What is the total mass of the shark?
b) What is the mass of the shark without the liver?
c) Which of the following expressions can be used for finding the overall (or 'average') density of an object made up of component B embedded in component A? (recall, p is the symbol for density)
1. paverage = pAMA + pBMB / MA + MB
2. paverage = pA + pB / 2
3. paverage = pA + pB / 2 (MA + MB)
4. paverage = pAMA + pBMB / 2
d) If the shark is precisely neutrally buoyant in salty seawater of density 1.05 kg/L, what is the density of the shark WITHOUT its liver?
