Identify the factors influencing buoyancy.
a) Volume of the liquid, Volume of the object
b) Volume of the object, Density of the liquid
c) Density of the object, Volume of the liquid
d) Density of the liquid, Mass of the object
Answers
Answer:
The buoyant force, which always opposes gravity, is nevertheless caused by gravity. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy.
Answer:
a) The factors that affect buoyancy are… the density of the fluid. the volume of the fluid displaced. the local acceleration due to gravity.
The buoyant force is not affected by… the mass of the immersed object. the density of the immersed object.
b) Volume and Density
The properties of a material may be described in many ways. Any amount of any substance will have a volume. If you have two containers of water that are different sizes, they each hold a different amount, or volume, of water. The unit for volume is a unit derived from the SI unit of length and is not a fundamental SI measurement.
c)The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.
d)
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth's density is 5.51 grams per cubic centimetre.
