What is average distance? The average distance is the average shortest path of a graph, corresponding to the summa of all shortest paths between vertex couples divided for the total number of vertex couples. In quantitative terms, “high” and “low” are better defined when compared to the total number of nodes in the graph. How […]

Why do cheetahs have very little genetic variation?
Why do cheetahs have very little genetic variation? Even though the number of cheetahs grew to as many as 100,000 during the 19th century, their genetic variability remained low due to the extreme bottleneck event that took place thousands of years previously. What are the two types of variation? There are two forms of variation: […]
What are examples of an unbalanced force?
What are examples of an unbalanced force? Practically anything that moves is a result of the exertion of unbalanced forces on it. If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This […]

Is freezing point depression positive or negative?
Is freezing point depression positive or negative? The change in the freezing point is proportional to the amount of solute added. This phenomenon is called freezing point depression. The change in the freezing point is defined as: ∆Tf = Tf,solution − Tf,solvent. ∆Tf is negative because the temperature of the solution is lower than that […]
What are the factors affecting the solubility?
What are the factors affecting the solubility? Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of […]
