Electrical Energy
Number of Words: 231 / Number of Pages: 1
... same time the voltage decreases. As a result the rate at which the capacitor is discharged, which is the current, is decreased. The outcome of this is that the capacitor will be completely discharged meaning that both the current and voltage will equal zero. At this time all the energy stored in the circuit will have been transferred to thermal energy at the resistor.
A heater uses electrical power. The power dissipated in a resistor is in return proportional to the resistance and the square of the current that passes through it. As the energy is changed from electrical to thermal the resistor gets hot ...

Landfills

... and pay to have them properly disposed of or stored ( 1).
There are many things deposited in . Garbage, rubbish, ashes, large wastes, dead animals, sewage-treatment solids, industrial wastes, mining wastes and agricultural wastes are all materials deposited in (SWD 1). Many of these materials, about 50%, could be recycled, like glass, plastic, paper, etc., instead of being put in . Some trash put in is biodegradable, and some will never decompose. Food, yard wastes and paper were found in from around 50 years ago, and they never did decompose. A newspaper was found dating back to earlier than ...

The Study Of Biology
Number of Words: 316 / Number of Pages: 2
... biology, which is closely linked with molecular biology. Cellular biology deals with the functions of the cell and the basic strucural unit of living matter; Finally, population biology became firmly established as a major sub division of biological studies in the 1970’s. This field relates with the study of gene changes in populations, and ecology.
Biology also includes the study of humans at the molecular, cellular, and organismal levels. If the focus of examination is the application of biological knowledge to human health, the study is often termed biomedicine. Human populations are by con ...

Cloning 3
Number of Words: 507 / Number of Pages: 2
... Cloning puts the work of God into our own hands. The creation of life then becomes a manufacturing of duplicates instead of a "creative act of God".
It is also important to consider the repercussions of cloning on the cloned individual. Numerous psychological problems may arise if a person discovers that he or she was cloned. How would a child feel if they found out that they were created to be used to donate organs or replace a lost loved one? A cloned child may also feel obligated to follow the pre-determined path of their gene donor. This would bring about a lot of confusion and emotional damage ...

Pesticides

... of Science (NAS), National Resources Defense Council (NRDC), and Consumers Union (CU), the EPA has made a notable progress. Throughout the years, consumers have pushed for research of the chemicals and substances that produce agricultural and what these do to our internal system. Congressman, James J. Delaney was also convinced that too many pesticide chemicals were found in foods. So in 1958, the House Select Committee investigated the use of chemicals in food products and amended section 409 of the FFDCA, in result creating The Delaney Clause.
The bill The Delaney Clause was implemented t ...

Cloning And Its Impact

... of livestock with genes that produce “super” livestock traits; however, this technique is not efficient because only five percent of the offspring express these “super” traits that would guarntee a more productive industry. Scientists can easily genetically alter adult cells; therefore, cloning from an adult cell would make it easier to alter the genetic material. The goal of transgenic livestock1 is to produce livestock with ideal characteristics for the agricultural industry and to be able to manufacture biological products such as proteins for humans.
Farmers are attempting to produce transg ...

The Black Hole
Number of Words: 1309 / Number of Pages: 5
... energy of the two gas clouds. This energy produced is so great when it
first collides, that a nuclear reaction occurs and the gases within the
star start to burn continuously. The Hydrogen gas is usually the first
type of gas consumed in a star and then other gas elements such as Carbon,
Oxygen, and Helium are consumed.
This chain reaction fuels the star for millions or billions of years
depending upon the amount of gases there are.
The star manages to avoid collapsing at this point because of the
equilibrium achieved by itself. The gravitational pull from the core of
the star is equal t ...

Prescribed Burning

... no guarantee you'll not get a big rip," (see terminology sidebar, page 57) says a Forest Service fire officer on the eastern seaboard.
"When you're messing with fire, there's always a chance one will escape," echoes his counterpart in California's Sierras.
"The fuels are tricky..." adds Ron Meyers, who directs prescribed fires for The Nature Conservancy from his base in Florida.
Such concerns are real.
Paul Tine, acting Forest Service fuels specialist for the sprawling eastern U.S. region, remembers well what he calls "the lowest day I've ever had in my 18-year career." As fire boss ...

Cd Roms

... you turn on your computer the information is always there for you when you need it.
A CD:ROM looks like a music compact disk , but they are not that much alike. First a CD:ROM has a lot more information than a regular compact disk. A CD:ROM has audio as well as visual information. Second a CD:ROM stores more data in it. Third if you put a CD:ROM in a compact disk player the compact disk player would just sit there and act stupid. If you put a compact disk in a CD:ROM drive it would play the compact disk you put in it because the CD:ROM drive is taught to do that also. Fourth to record music onto ...
