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 kgbull 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?

866.92 N

Explanation:

mass of shark, m = 92 kg

density, d = 1040 kg/m^3

Volume, V = mass / density

V = 92 / 1040 = 0.08846 kg/m^3

The lift force is the buoyant force acting on the shark is

Lift force = Volume x density of water x g

Lift force = 0.08846 x 1000 x 9.8

Lift force = 866.92 N

Thus, the lift force is  866.92 N.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
