Can an altitude be a median? The altitude is also a median. This means triangle ABC must be an isosceles triangle such that AB = BC (Note that the altitude is drawn from vertex B here). What is altitude of a right triangle? Definition: Altitude of a triangle is the perpendicular drawn from the vertex […]

What are the causes and effects of eutrophication?
What are the causes and effects of eutrophication? “Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”. What can humans do to […]

Is cooking a chemical change?
Is cooking a chemical change? Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. An unexpected color change or release of odor also often indicates a chemical change. What type of chemical […]
Why is the potential energy of a free particle zero?
What increases when frequency increases?
What increases when frequency increases? From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic. What is the highest frequency ever generated? At least ~100 GeV, which corresponds to 2*1025 Hz. I […]

Why can some mixtures be separated by chromatography?
Why can some mixtures be separated by chromatography? Chromatography can be used to separate mixtures of coloured compounds . As the solvent soaks up the paper, it carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out. How many main ways are there to separate […]
