telephone‚ or a person’s vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them‚ and so on. The pattern of the disturbance creates outward movement in a wave pattern‚ like waves of seawater on the ocean. The wave carries the sound energy through the medium‚ usually in all directions and less intensely as it moves farther from the source. Prequency and Wave Length In physics‚ the wavelength of a sinusoidal wave is the spatial period

Titanium Titanium is a transition metal that was discovered in the year 1791 by an English pastor named William Gregor. The discovery was made when Gregor was by a Stream in the parish of Mannacan in Cornwall‚ England and found black magnetic sand. When Gregor analyzed this sand‚ he found out it was made up of the oxides of iron and an undefined and yet undiscovered metal.

[1] Gandhi led nonviolent demonstrations as the people defied British policy by making salt from seawater. The British would soon respond by brutally beating the peaceful demonstrators bringing international outrage. By August 1947‚ Britain caved in to the pressure granting India its independence.

-Bioremediation is the use of micro-organism metabolism to remove pollutants. Technologies can be generally classified as in situ or ex situ. In situ bioremediation involves treating the contaminated material at the site‚ while ex situ involves the removal of the contaminated material to be treated elsewhere. Bioremediation can occur on its own (natural attenuation or intrinsic bioremediation) or can be spurred on via the addition of fertilizers to increase the bioavailability within the medium (biostimulation)

There are many technological solutions that could potentially help to alleviate the current water shortage on Oahu. For the purpose of this paper‚ our group has chosen to discuss what we believe to be the top three most feasible technological solutions. In order of current usability they are; 1. Water recycling 2. Desalination 3. OTEC (Ocean Thermal Energy Conversion) Water Recycling Water recycling here on Oahu is an important part of ensuring a sustainable water supply for future generations

Japan was hit by an enormous earthquake on March 11‚ 2011‚ that triggered a deadly 23-foot tsunami in the country’s north. The giant waves deluged cities and rural areas alike‚ sweeping away cars‚ homes‚ buildings‚ a train‚ and boats‚ leaving a path of death and devastation in its wake. Video footage showed cars racing away from surging waves. The United States Geological Survey reported the earthquake and on Monday revised its magnitude from 8.9 to 9.0‚ which is the largest in Japan’s history. The
