In order to extract energy from ocean waves, one must first understand how waves are formed. Solar radiation from the sun is absorbed differently on the earth’s surface. The imbalanced heating of the earth’s surface causes the warm air to expand and rise, whereas the cool air sinks due to its higher density, thereby generating a pressure gradient. In order to return to an equilibrium state, the air from the high pressure zone has to replace the air in the low pressure zone. The movement of…

The historic launch of the Apollo 11 mission carried three astronauts toward the moon. Two astronauts Neil Armstrong and Buzz aldrin set foot on the moon for the first time in human history as 530 million people around the world watched their mission on television. The first moon landing was launched on july 16 1969 in order to complete a national goal set by President John F. Kennedy. Apollo 11 was the first manned mission to land on the Moon. The first steps on the moon were taken by Neil…

The Formation of Australia Although Australia has the least surface area compared to other continents, it does have a long geological history. Australia is formed by many geological elements resulting in the present-day Australia. Continental drift is the movement of the Earth's continents shifting (Appearing to be 'drifting') on Earth's surface. There have been many supercontinents, throughout history, which had existed on Earth's surface for millions of years. Supercontinents are a cluster…

Dofasco Acid STSE 1. Summarize this article in your own words. Include all the main points. (4) On September 7, a burst pipe at ArcelorMittal Dofasco sprayed hydrochloric acid mist through the Crown Point neighbourhood, which runs south of the plant. The Hamilton’s public health department is gathering information on this incident and its impact on the neighbourhood from the Ministry of Environment and ArcelorMittal. Evidence of the leak was witnessed across Crown Point neighbourhood. Residents…

significantly limited. Theories of what may rest on the planet’s surface were left unrequited until a handful of scientists and engineers went to work on what would become one of the most significant space missions of all time – Viking. The twin launches of Viking 1 and 2 completely changed our understanding of Mars, the capability of robotic missions, and whether or not there is other…

would not be able to tell him until the time is right. So Zeus tries and tries to get it out of her, but fails. Cloudia later finds out that is she goes to the surface for a day, she will finally be able to see. But Zeus doesn’t want her to risk being killed and tells her no. Zeus and his refusal to allow her to go the surface…

The surface of Venus was mapped in 1991 by the Magellan expedition, which revealed evidence of extensive volcanic activity on the planet--yet the timing of this volcanic activity remains a mystery. About 80 percent of Venus' surface is covered in volcanic material. Most of the volcanoes are believed to be inactive, yet there is some evidence to suggest more "recently" activity ("recent" in this context meaning within the last 500 million years). There are no lava nor caldera (craters created…

collect the secondary electrons and can be converted into electrical signal. These signals can be fed into CRO through video amplifier as shown. In order to produce images the electron beam is focused into a fine probe, which is scanned across the surface of the specimen with the help of scanning coils is shown in Fig. 2.6. Each point on the specimen that is struck by the accelerated electrons emits signal in the form of electromagnetic radiation. Selected portions of this radiation, usually…

third type of colloidal system. Association colloids are micro heterogeneous system, here the particles of the colloidal dispersed phase formed agglomeration of molecules or ions of the substance dissolved in the dispersion medium. Amphiphile or surface active agents are characterized by two distinct region of opposing affinities with the same molecule or ion. When the liquid medium present at low concentration, the amphiphiles exist separately and the size to be subcolloidal. As a concentration…

Lo- moon. Lo is about 4.5 billion years old-same as Jupiter. Lo is the fifth moon from Jupiter. Lo is slightly larger than Earth’s moon. Lo is tidally locked, so the same side always faces Jupiter. Lo’s surface temperature averages about minus two hundred two degrees fahrenheit. But oddly enough Io's volcanos can reach to three thousand degrees fahrenheit. The interior of Lo is composed of an iron or iron sulfide core and a brown silicate outer layer. Lo…
