Weight can be described as a quantity that represents the exerted force on particles by acceleration fields, especially the earth’s gravitational field on its surface. In SI units is expressed in regard to force while in Newton’s theory it is exerted to mass in regard to gravity. The standard unit for measuring weight is Pound (lb) and this is technically the force that gravitational acceleration [...]

A footnote refers to text notes that are placed at the bottom part of a page in a document or book. These short notes usually comment or make some reference to the details in the body of the main text. It is usually marked with a number, which is written in superscript. In some cases the number denoting the footnote may be in parentheses or brackets. There are also some symbols that may be used to [...]

Until the Treaty of Paris signed in 1783 that recognized independence of the United States of America, the name 13 colonies was used in the Great Britain to refer to the 13 states of America. These states were founded in the years between 1607 and 1733. They were colonized by Great Britain and were also known as British America. The colonies in the north started rebelling against the taxation rule [...]

Sight words may be referred to as any words that are known by readers automatically. The pronunciation of sight words is carried out without the spelling of the word being decoded. The name given to a child is a common primary sight word. Beginning readers are at an advantage when they commence learning the means of reading sight words that frequently occur in print including those on Fry word-lists [...]

The term whole number is a mathematics term just like natural and integer numbers. Basically, a whole number’s definition is centered on what it cannot be. A whole number cannot be a percentage, fraction nor have a decimal. One will also hear natural numbers being called counting numbers. These are the first numbers learned by children and they entail zero and all the numbers above and below zero [...]

A tide occurs to the changes in the earth’s ocean surface caused by tidal forces of the sun and the moon periodically. The gravitational attraction between the moon and the sun to the earth and the fact that the force is greater between the moon and the earth surface is greater than that between the sun and the earth causes the sudden tidal waves. The difference in the attraction arises since the [...]

A Hurricane can be described as a large tropical storm that is accompanied by heavy winds. By definition hurricanes contain winds that have a speed of 119 km per hour (74 miles per hour) and big areas of rainfall. Additionally, hurricanes can potentially spawn very dangerous tornadoes. The excessive rainfall and string winds also have the ability to produce abnormal flooding and rise in sea level. [...]
