Planet From The Sun Solar System
1,232 words... eld, it is so week that no instrument has been able to detect it. Mars like the Earth is tilted on its rotational axis. Liquid water cannot exist on Mars's surface because of the low temperature and pressure' water exists only as ice deposited at the poles and perhaps trapped below the surface and as vapor in the atmosphere. Mars is very desolate and barren and is covered in craters and are prone to violent sandstorms. The UV radiation of Mars would kill any known life. Mars has the largest ...

How Chinese Rudder Effected Christopher Columbus
1,541 wordsThe development of the rudder was one of the most important sea navigational inventions that have ever been invented. Before the twelfth century in northern Europe, ships were steered by a quarter-rudder mounted on the stern side of the vessel. Up until the fourteenth century the use of the quarter rudder persisted in the Mediterranean. Two quarter-mounted steering oars were used. By age of exploration, the pintle-and-gudgeon rudder, hung from the sternpost had replaced quarter-rudder. The rudde...

High Duro Meter 3 The Boot Wheels
463 wordsThe diameter is the height of the wheel, which ranges from 43 to 80 mm. As diameter increases, cruising speed increases and maneuverability decreases. (2) The duro meter is the hardness of the wheel. Wheels use the A scale from 0 - 100. 100 would be a very hard plastic. Softer wheels have more shock absorption, greater turning ability, and wear faster. (2) A wheels profile is the point where the wheel touches the ground. Traction and stability increase with an increasing profile thickness. (2) T...

Fuel Economy Commonly Referred
1,489 wordsThe idea of forced air induction by turbine, or turbo, is not new and has it's mass production roots in WWII fighter planes. What is new, however, is its application to passenger automobiles. Unlike a near constant high RPM fighter engine, an automobile requires wide-open throttle (WOT) power availability throughout its entire operating range. Previous automotive turbo applications acted like an on-off power switch with a five second delay, decreasing drivability, rather than providing the smoot...

Cross Sectional R R
864 wordsDetermination of r for a Metallic Conductor To determine the resistivity (r) of a given sample of wire Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R = Voltage / Current Resistance of a co...

Radio Telescopes Radio Waves
1,285 words... copes Orbiting telescopes are used to observe the ultraviolet (UV), far infrared, and X-ray portions of the electromagnetic spectrum. The Infrared Astronomical Satellite, placed in orbit in 1983, carried a 22. 5 -inch infrared telescope. Because all matter emits infrared radiation if warm, technologists had to cool the telescope to near absolute zero with liquid helium so its internal heat radiation would not mask radiation it was collecting from deep space objects. Among its many discoverie...

Speed Of Light Degrees Celsius
1,124 wordsThe Properties of Light Applied to Fibre Optics One of the basic properties of light is that it travels in straight lines and can have it? s direction changed. This is the property which is applied to achieve the purpose of Fibre Optics which is to carry light from one place to another. The way this is done can be explained by the principle of refraction. This is the principle which governs the behaviour of light as it passes from one transparent substance to another. It states; if a ray of ligh...

3,974 wordsDoes a God Exist? Either God exists or He doesnt. There is no middle ground. Any attempt to remain neutral in relation to Gods existence is automatically synonymous with unbelief. It is far from a simple clear cut question, for if God does exist, then nothing else really matters; if He does not exist, then nothing really matters at all. If He does exist, then there is an eternal heaven to be gained (Hebrews 11: 16) and an eternal Hell to be avoided (Revelation 21: 8). The question for Gods exist...

Cast Iron Common Place
2,441 wordsI-How Does Gears Work? You see gears in just about everything that has spinning parts. For example, car engines and transmissions contain lots of gears. Gears are generally used for one of four different reasons: 1 - To reverse the direction of rotation. 2 - To increase or decrease the speed of rotation. 3 - To move rotational motions to a different axis. 4 - keep the rotation of two axis synchronized. Most of the gears you see in real life have teeth. The teeth have three advantages: 1 - They p...
