In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids.

A fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases and plasmas. Fluids display properties such as flow, pressure, and tension, which can be described with a fluid model. For example, liquids form a surface which exerts a force on other objects in contact with it, and is the basis for the forces of capillarity and cohesion. Fluids are a continuum (or "continuous" in some sense) which means that they cannot be strictly separated into separate pieces. However, there are theoretical limits to the divisibility of fluids. Fluids are in contrast to solids, which are able to sustain a shear stress with no tendency to continue deforming.

I know that the apparent weight or the apparent mass multiplied by G is equaling the mass of the metal, the true mass of the metal times G minus the reinforce. And so this would be equaling the mass of the metal multiplied by G minus, the volume of the metal multiplied by the density of water multiplied by G. And so we can say that the apparent mass times G would be equaling the mass of the metal times G minus the mass of the metal divided by the density of the metal. This is ah, due to the definition of what volume is and then multiplied by the density of water times G. And so we find that we can cancel out G's and we find that the density of the metal is equaling the mass of the metal divided by the actual mass of the metal, minus the apparent mass of the metal multiplied by the density of water and we can solve. So this would be for the denominator 63.5 grams minus 55.4 grams. And for the numerator again, 63.5 grams, This would be multiplied by the density of water, 1000 kilograms per cubic meter and we find that the density of the metal is equaling approximately 7800 and 40 kilograms per cubic meter. Based on this value, um, the metal is most likely Iron Effie or steal, which is steel, which is essentially iron with a bit of carbon added to it. But because carbon is so right, it won't affect the density much. So it's either iron or steel. That is the end of the solution. Thank you for what?
