I suspect that the answer is specific gravity but, with only part of the question being visible, it is hard to be sure.
There is no weight ratio for height. The weight of an object depends on its the volume and density. The volume depends on the height as well as the average cross section so height, alone, cannot determine weight.
It is the cube of the ratio of lengths of their edges.
the weight of the displaced water is equal to the weight of the object
That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
You should have equal ingredients according to the weight of the eggs.
Specific gravity.
This ratio is called the specific gravity.
Without knowing the weight to volume ratio of the item in question, there is no way to convert the weight to a volume.
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
Mixed by volume and by ratio.
There is no weight ratio for height. The weight of an object depends on its the volume and density. The volume depends on the height as well as the average cross section so height, alone, cannot determine weight.
It is the ratio of an object's weight to its volume. Alternatively it can be said, it is the weight of the object per unit of volume.
No, it is equal in volume.
According to Archemedes' Principle, when a body (solid) ispartially or fully immersed in a liquid then the body loses a part of its weight. The weight lost by the body is equal to the volume of liquid displaced by the solid body. In order to compare the density of water and coke, you have to immerse a solid object in water and note down the apparent decrease of weight of the object. Then we have to immerse the same object in coke and note down the apparent decrease in weight of the object. The ratio of these two readings is equal to the ratio of weights of equal volume of water and coke. Hence, it is equal to the ratio of densities of water and coke.
Weight (divided by) Volume
It is the cube of the ratio of lengths of their edges.
The rate of diffusion would be faster for the right cylinder.
