How are atoms linked?
How are atoms linked? Molecule is the general term used to describe any atoms that are connected by chemical bonds. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. What are three parts of an atom? Our […]
What is the symbol for phase difference?
What is the symbol for phase difference? (symbol: ϕ) The difference in phase between two sinusoidally varying quantities of the same frequency. What is meant by phase diagram? Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on […]
Is the Grand Canyon a result of the flood?
Is the Grand Canyon a result of the flood? On sale since last summer, “Grand Canyon: A Different View,” by veteran Colorado River guide Tom Vail, asserts the Grand Canyon was formed by the biblical flood that Noah’s ark survived, and can be no more than a few thousand years old. Does the Grand Canyon […]
How does the kinetic energy of a moving body depends on its 1 speed and 2 mass?
How does the kinetic energy of a moving body depends on its 1 speed and 2 mass? Hence, kinetic energy is directly proportional to mass of the body and directly proportional to the square of the speed of the body. How does the kinetic energy of moving body depends on its speed? (i) Kinetic energy […]
What did John Locke mean by social contract?
What did John Locke mean by social contract? John Locke’s version of social contract theory is striking in saying that the only right people give up in order to enter into civil society and its benefits is the right to punish other people for violating rights. No other rights are given up, only the right […]
What are reactive metals used for?
What are reactive metals used for? Reactive metals, such as magnesium, are widely used in rust prevention and are known as sacrificial anodes. Iron will rust unless protected in some way. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting. What are the five key […]
Where are land breezes the strongest?
Where are land breezes the strongest? Land breezes are strongest along the immediate coastline but weaken considerably further inland. Land-breeze circulations can occur at any time of year, but are most common during the fall and winter seasons when water temperatures are still fairly warm and nights are cool. What breeze blows from land to […]
What is Gaussian surface and its importance?
What is Gaussian surface and its importance? Gaussian surface is a closed surface in three dimensional space through which the flux of a vector field is calculated; usually the gravitational field, the electric field, or magnetic field. The concept of Gaussian surface helps in evaluatig the electric field intensity due to symmetric charge distribution. What […]
Which component of magma is the highest and the lowest in value?
Which component of magma is the highest and the lowest in value? Felsic magma has the highest silica content of all magma types, between 65-70%. As a result, felsic magma also has the highest gas content and viscosity, and lowest mean temperatures, between 650o and 800o Celsius (1202o and 1472o Fahrenheit). Could a mountain turn […]
