.... cars. Just because we have these in our cars however, doesn't mean that we won't get lost, but it is more difficult to get lost, and it's definetly easier to find your way around if you do get lost. When get in your car, all you have to do is type in your destination and the computer will show you where your destination is, aswell as how to get there and the easiest and fastest way to get there. These systems are being used to make everything more convenient, easier, safer, and quicker for not only the user of the navigation system but everyone else too; for example, if someone is hurt, or .....

.... going down forces the rocket in the exact opposite direction the water goes. Which is why one time when we shot the rocket it flew at an angle. Also it shows why the launchers had stoppers, because if they didn’t the cork wasn’t strong enough to hold that pressure and would cause the rocket to begin flight prematurely. His second law can be used to describe how high and fast the rocket will go. If you wanted it to go really high and fast you would just pump more pressure into it then if you didn’t want it to go that high. You can determine how much force is needed by multiplying t .....

.... surface. This heat energy then radiates upward into space. There the greenhouse gases found naturally in the troposphere absorb some of the infrared radiation. The gases insulate the Earth, but do eventually allowing some of the heat to escape. The rest of the heat reflects back down to earth where it is bounced back up again. Almost like an ongoing game of ping-pong. With more of the greenhouse gasses being let out into the atmosphere, there are more ping-pong balls going back and forth. Granted, without these greenhouse gasses, the earth would almost freeze and fall into another ice age, .....

.... copper and copper ore are usually found. The highest grade of copper ore is pale silvery gray. Miners used to be always in danger in copper mines. Today, we have reduced a fair amount of these hazards. Miners wear hats made of iron or very hard plastic. This is to protect them from falling rocks. Lamps are also attached to these helmets in case some of the lighting in the mine goes out leaving a miner stranded in the dark. One of the biggest problems with mining is that in some places dangerous gas’s may exist, like Carbon Monoxide. In the past we had very cruel and inhuman ways to dete .....

.... and modems, subscription-based services such as America Online (AOL), Prodigy, and Compuserve, where consumers are able to check airline flight schedules and make reservations, purchase a wide variety of products, and discuss product performance with other consumers, are becoming very popular. Households in Chicago and San Francisco can purchase groceries from home using computer software marketed by Peapod, Inc. This latter service allows consumers to search within a product category using attributes such as price, calories, sugar content, and package size. Car manufacturers such as BMW .....

.... the common giraffe (Giraffa camelopardalis), and the reticulated giraffe (Giraffa cameloparadalis reticula). These two subspecies have formed on different sides of the Tana River in Kenya. They are phenotypically distinct, and can only produce fertile offspring in zoos. Sympatric speciation occurs when two segments of the same species occupy a geographical area without interbreeding. Each new species, or subspecies, adapt to a specific environmental niche (adaptive radiation). Two segments of the same species Adapted to different niches An example of sympatric speciation is the genu .....

.... Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly affects how fast we can access the Internet today, at speeds of only 53kbps. Even that connection speed is theoretical. Depending on the quality of the telephone lines that run into your home, your connection speed may not even come close to 53kbps. Despite hav .....

.... billion years, the entirety of our universe was compressed into the confines of an atomic nucleus. Known as a singularity, this is the moment before creation when space and time did not exist. According to the prevailing cosmological models that explain our universe, an ineffable explosion, trillions of degrees in temperature on any measurement scale, that was infinitely dense, created not only fundamental subatomic particles and thus matter and energy but space and time itself. Cosmology theorists combined with the observations of their astronomy colleagues have been able to reconstruct the .....

.... atom. This "muo-atom" the n captures another nucleus. The muon orbits more tightly around the two captive nuclei leading them to overcome their natural repulsion of each other and fuse. This reaction produces a larger nucleus that almost immediately shatters, releasing energy. It also frees the muon, which can then repeat the cycle, causing several hundred more such fusions. The fact that the muon is 207 times heavier than an electron gives support for this theory. A nuclei is orbited by an electron making a mini- solar system. If a muon is shot at the nuclei, it will bump .....

.... energy in the U.S. They are a great source of power, but unfortunately they also have many setbacks. The finite reserves of fossil fuels are being depleted at a rate one hundred thousand times faster than they are being formed. As supplies decrease we become more and more dependent on the Middle Eastern countries for our supplies of oil, recently, fifty-two percent of imported oil came from such countries. The most significant drawback is the amount of pollution produced by fossil fuels.(5) These negative impacts can be lessened and even eradicated through the use of renewable energy. T .....
