What does d2y dx2 mean? second derivative How can you tell dy dx? Derivatives as dy/dx Add Δx. When x increases by Δx, then y increases by Δy : y + Δy = f(x + Δx) Subtract the Two Formulas. From: y + Δy = f(x + Δx) Subtract: y = f(x) To Get: y […]
Are ecoregions bigger than ecosystems?
Are ecoregions bigger than ecosystems? An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. What is an example of an ecoregion? Ecoregions are defined by soil type, climate, temperature, precipitation and other characteristics. For […]

What is the difference between two isotopes of an element?
What is the difference between two isotopes of an element? Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope […]
Where does mine waste go?
Where does mine waste go? All mines generate waste, one type of which is known as “tailings”. Often these solid wastes are stored at or near the mine site itself. Mine site rehabilitation can be expensive, and often the burden falls on the taxpayer rather than the mining company. Why are tailing ponds bad? The […]
How harmful is radiation from cell phones?
How harmful is radiation from cell phones? Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, “there is currently no consistent evidence that non-ionizing radiation increases cancer risk in […]
How fast is considered relativistic?
How fast is considered relativistic? Physics close to the speed of light Special relativity, developed by Albert Einstein, applies to situations where objects are moving very quickly, at speeds near the speed of light. Generally, you should account for relativistic effects when speeds are higher than 1 / 10th of the speed of light. What […]
What happens to the brightness of bulb A when the switch is closed and bulb B lights up?
What were the impacts of the scientific revolution?
What were the impacts of the scientific revolution? The scientific revolution, which emphasized systematic experimentation as the most valid research method, resulted in developments in mathematics, physics, astronomy, biology, and chemistry. These developments transformed the views of society about nature. How would you explain the causes and impact of the scientific revolution? Causes: Renaissance encouraged […]
How are water properties important to life?
How are water properties important to life? Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or […]
