Black Holes
Number of Words: 688 / Number of Pages: 3
... hole. As the horizon is approached from
outside, time slows down relative to that of distant observers, stopping
completely on the horizon. Once a body has contracted within its
Schwarzschild radius, it would theoretically collapse to a singularity—that
is, a dimensionless object of infinite density.
Formation
Black holes may form during the course of stellar evolution. As
nuclear fuels are exhausted in the core of a star, the pressure associated
with their heat is no longer available to resist contraction of the core to
ever higher densities. Two new types of pressure arise at densities ...

Acid Rain 5
Number of Words: 3019 / Number of Pages: 11
... information was organized from various websites. It also contains information from a newspaper article about a new monitoring site for acid rain in Irish Cove located in Cape Breton, Nova Scotia.
ACID RAIN
The atmosphere, unpolluted, is the means of life on earth. It is a thin layer of gases which surrounds our planet. It is known that without the atmosphere our planet would be inhabitable, but we continue to put numerous amounts of toxic waste into it. The burning of fossils fuels, produces gases that cause acid rain. Acid rain is harmful to forests, lakes, rivers, and any wildlife t ...

... a visible boundary. On the opposite end the northern hemisphere consists of a wider variety of geological features, but is obviously smoother and much younger. There are large volcanoes, a great rift valley, and a variety of channels.
Volcanism is a geological process that occurs on Earth today, and has on many planetary bodies throughout the history of the solar system. No volcanism is occurring on the surface of Mars today. In the past, however, volcanism was one of the main forces creating and reshaping the surface of the planet. All of the rocks that have been observed by the Viking lander ...

The Beauty Of Rainbows
Number of Words: 252 / Number of Pages: 1
... facts about rainbows.
First of all a rainbow is a curve of colored light which is seen in the
sky. Rainbows can be seen in moonlight or in artificial light. They are caused
by the sun shining through tiny drops of water in the air. A rainbow's
brightness depends on how large the drops are. The larger the drops are the
brighter the rainbow will be.
Many people think that a rainbow is only made of six colors, but it is
really make of seven. The colors in order are red, orange, yellow, green, blue,
indigo, and violet. A primary rainbow is a rainbow with red on the outside and
violet on th ...

Advantages Of Producing Crops Through Use Of Hydroponics
Number of Words: 302 / Number of Pages: 2
... water, lack of
suitable soil, high labor cost of traditional cultivation, high cost of
sterilizing soil, and there is a greater reliability and predictability of plant
production. In addition, It's easy!
Depending on what is being grown, most of the time hydroponic plants
require less attention than soil-grown crops. Because of this, it can relieve
some people of the added responsibility that soil-grown plants require.
As one can see, there are many advantages to this system of growing
plants. Since its origination, thousands of companies have sprung up dealing
solely with hydroponics and hydropon ...

... an initial guess
close to the root because some functions have multiple roots. Failure to choose
an initial value that is close to the root could result in finding a the wrong
root or wasting a lot of time doing multiple iterations while getting close to
the actual root.
On some occasions, the program cannot find a root to an initial guess
that is placed into the program. In some instances Mathmatica could not find
the root to the function, like if it is a parabola with its vertex is placed
right on the y axis with its roots an equal distance away in both directions.
In a case like this, the c ...

Voltage: Ohm's Law And Kirchhoff's Rules
Number of Words: 879 / Number of Pages: 4
... ..... +1/Rn .
Complex dc circuit involving a combination of parallel and series resistors can
be analyzed to find the current and voltage at each point of the circuit using 2
basic rules formulated by Kirchhoff. 1) The algebraic sum of current at any
branch point in a circuit is zero. 2) The algebraic sum of potential difference,
V, around any closed loop in a circuit is zero. These rules and equations
provided by the Ohm's law and the Kirchhoff rule can be experimentally tested
with the apparatus available in the lab
EXPERIMENTAL METHOD
The apparatus used in the experiment includes a Voltmeter, ...

Heart Murmurr
Number of Words: 888 / Number of Pages: 4
... the baby grows, the murmur will become softer and many times disappear altogether. Another common innocent murmur heard in children ages 3 to 8 years is a vibratory musical murmur called a Still's murmur. No one knows the cause of the murmur other than blood flowing through a healthy vigorous heart. The murmur is usually detected at a well-child visit or if the child comes in with fever or some other form of illness. In times of fever or illness, the murmur will be louder because the heart is pumping harder, and blood is flowing through the heart faster. The murmur tends to become softer as the child g ...

ADHD ON INTELLIGENCE

... of ADHD on child intelligence. Testing and treatments of those with ADHD will also be discussed. In accordance with Dulcan et al. (1997) ADD, ADD-H, ADHD, although not identical, will be considered interchangeably due to similarity.
Characteristics and Testing of ADHD Intelligence
Even though ADHD occurs in people of every intelligence, a majority of children affected experience academic problems. These children may have specific learning disabilities, such as dyslexia, or may have multiple learning problems (Beiderman et al., 1993). In a study by MacLeod et al. (1996) comparing ADHD childre ...
