Sharks are generally negatively buoyant; the upward buoyant force is less than the weight force. this is one reason sharks tend to swim continuously; water moving past their fins causes a lift force that keeps sharks from sinking. a 92 kg bull shark has a density of 1040 kg/m3. what lift force must the shark's fins provide if the shark is swimming in seawater? bull sharks often swim into freshwater rivers. what lift force is required in a river?

8.67807 N

34.7123 N

Explanation:

m = Mass of shark = 92 kg

= Density of seawater = 1030 kg/m³

= Density of freshwater = 1000 kg/m³

= Density of shark = 1040 kg/m³

g = Acceleration due to gravity = 9.81 m/s²

Net force on the fin is (seawater)

The lift force required in seawater is 8.67807 N

Net force on the fin is (freshwater)

The lift force required in a river is 34.7123 N

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
