Buoyancy

Question 1

Define Archimedes Principle.

Answer 1

A body immersed in a fluid experiences an up-thrust (Buoyancy) equal to the weight of the displaced mass of the fluid.

Question 2

How do you calculate Buoyancy?

Answer 2

A (buoyancy) = Vpw g

Vpw = volume of animal
g = acceleration due to gravity.

Question 3

How do you calculate the weight of an animal?

Answer 3

W = Pa g

Pa = average density of animal.
g = acceleration due to gravity.
