How can you recycle paper for cash?

Many areas offer government-run free recycling service for paper products, but these programs typically don't pay people. While most recycling centers accept paper from anyone who brings it, collecting a significant amount of paper can be difficult due to its size, and some areas forbid people form storing paper in their yards. However, people with storage space and an appropriate vehicle might be able to offer pickup services for local companies.

What determines the reactivity of a metal?

Metals are electropositive elements. They have few electrons in their outermost energy levels, so they won't hold onto them very tightly. These valence electrons are often given away to more electronegative atoms such as the nonmetals, making metals electron donors. The most reactive metals on the periodic table are the alkali metals, which have a single valence electron. According to HyperPhysics, alkali metals include potassium, sodium and cesium. The next reactive series of metals are the alkaline earth metals such as magnesium and calcium that have two valence electrons.

What is the primary purpose of an astronomical telescope?

Using light reflection, an astronomical telescope enhances the brightness of a planet from a vantage point on the Earth. This factor allows for much greater detail than one can see with the naked eye. Enhanced resolution improves clarity. The magnifying power of top telescopes also make distant planets and solar bodies appear much larger to the observer.

What is the inside of the elbow called?

The elbow contains many ligaments and tendons in addition to bones. The inner elbow is just one component of the complex hinge-like structure that is collectively referred to as the elbow. The elbow is important for many tasks and activities and is vulnerable to injuries. On the inner elbow, tendons and ligaments may be injured by certain activities, which is referred to as medial epicondylitis.

What is the difference between a hurricane and cyclone?

In addition to hurricanes and cyclones, the term typhoon is used to describe the same weather phenomenon in the Northwest Pacific. These forces of nature occur when a series of weather issues or anomalies combine. Warm tropical oceans, moisture and fairly light winds combining with a pre-existing weather condition cause hurricanes, cyclones and typhoons.\nWhen these conditions persist for long periods of time, they combine to create the dramatic events one often associates with typhoons, hurricanes and cyclones. These events might include devastating floods, dangerous winds and torrential down..

What is magnetic declination?

Magnetic North is the direction indicated by a compass when pointed towards the magnetic North Pole. True North, also called "geodetic North," is the path a meridian follows to the geographic North Pole. Magnetic declination is the angle of difference between the two. For example, in a location where the declination is 10 degrees West, true North would actually be 10 degrees East of the direction indicated by the compass.\nAmerican mathematician and author of "The New American Practical Navigator" formally defined magnetic declination as ?the angle between the magnetic and geographic meridians..

What is the largest moon in the solar system?

Ganymede was discovered by astronomer Galileo Galilei and was one among four moons that Galileo observed through his telescope. Ganymede's size even surpasses another planet in the solar system, Mercury. Ganymede is large enough that it could have been a planet had it orbited the sun instead of Jupiter.\nA unique feature of Ganymede is that of all the other moons in the solar system, it is the only one possessing a magnetic field generated by its metallic iron core. Surrounding the iron core is a mantle made up of rocky material. Above the rocky mantle lies an icy shell that also forms th..

Has anyone ever been lost in space?

The fatalities in human space travel include the shuttle crews of the Challenger in 1986 and the Columbia in 2003, as well as a single cosmonaut in Soyuz 1 and the three-man crew of Soyuz 11. The Challenger exploded during lift off, while the Columbia broke up before landing. Soyuz 1 crashed to Earth after a malfunction, and Soyuz 11 depressurized during re-entry, killing its crew.

What is hydrochloride?

Reaction of hydrochloric acid with a basic molecule results in a salt consisting of the base and the proton from hydrochloric acid and the negatively charged chloride ion. When mixed in aqueous solution, the base and chloride ion dissociate in the same way that sodium chloride dissociates into a positively charged sodium ion and a chlorine ion in water.\nThe positive charge imparted by the proton to the base allows it to be soluble in water. As many organic compounds are not normally soluble, this is valuable in chemistry for allowing solutions of these molecules to be made. In medicine, many ..

How often do hurricanes occur?

Hurricanes most often start in tropical areas near the Tropic of Capricorn or Tropic of Cancer. Wind and air movements in the regions north or south of the tropics help to produce the spinning effects of the hurricanes that are formed. Because of this, it is actually rare for a hurricane to form close to the equator. Hurricanes do not travel over land, and therefore dissipate shortly after reaching a shore. However, the effects of a hurricane, such as storms, rain, wind and other adverse weather patterns can be evident farther into land masses.A hurricane also cannot develop over bodies of wat..
