A motif is a recurring symbol which takes on a figurative meaning. We see them in books, films, and poems. In fact, almost every text commonly uses the literary device of the motif. A motif can be almost anything: an idea, an object, a concept, a character archetype, the weather, a color, or even a statement.
The Specific Gravity of liquids and solids is defined as a dimensionless unit which is the ratio of density of a material to the density of water at a given temperature, where density is defined as the materialâs mass per unit volume and is measured in kg/m 3.
In physics, a substanceâs specific gravity is the ratio of that substanceâs density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m3, that ratio is easy to find. For example, the density of gold is 19,300 kg/m3, so its specific gravity is the [â¦]
