When making connections it is so much easier to splice the copper cable than it would be for the fiber. Copper cables are also very flexible; you can have your wire go wherever without cracking or breaking. As for the disadvantages, all the advantages of the fiber are the downfall of the copper cabling. People want faster, better, farther. So, over time, we will lose the copper cables and move onto the
The way the wind blow depends on the ground surface, bodies of water, and the vegetation. Wind turbines used to generate electricity can harvest the wind. They convert kinetic energy from the wind into mechanical energy. The turbine spins like a propeller on a plane when the wind blows, turning the blade that spins a shaft connected to a generator that makes electricity. The mechanical power is converted into electricity to power homes and businesses.
Explain how human interference in the water cycle can affect water availability The water cycle is the process of evaporation, condensation and precipitation of water on Earth including rain water and how it is distributed. Human factors such as forest clearing, urban construction and changes in land use can all affect the distribution of water. Infiltration can be affected by forest clearance. This also affects perlocation and the water table. When there is rain the forests holds a lot of rainfall to the soil through roots of plants.
Wind turbines are clean, effective and nonpolluting; however, one cannot predict the speed or direction exactly. The heavier populated areas require more energy. Not enough wind and the turbine will not turn. Wind turbines are noisy, threatens wild life, and is an eye sore along with costly for the initial funding. Solar energy is a non-pollutant, cost effective, maintenance free, life span of up to 40 years; however the upfront cost is enormous, and not everyone can afford the cost to put the stylish panels on their roof tops.
It also has high social acceptability as it is cheap, not dangerous and not power plants are in industrial areas away from homes so it has limited NIMBY issues and noise, light and visual pollution. Wind power has medium social acceptability due to its noisiness and ugliness and positioning near residential areas causing NIMBY issues, however it is popular to some as it is a renewable and green energy source, this means it has low environmental impacts. It has medium economic cost as each turbine costs a lot and only produces a little amount of energy, however it is almost free to run after start up costs. Biofuels have high social acceptability, low cost and low environmental impacts because they are
Therefore manufacturers make bigger profit. As well as that, there are fewer factory regulations at sweatshops because the health and safety regulations aren’t as important in LEDC’s, that way it makes it cheaper to run the factory. As well as that, renting and buying the factory is cheaper too because the economy of LEDCS are weak the demand of buying property is low because not many people can afford it therefore buildings and houses are worth less because of low demand. Another reason clothes are manufactured in LEDCs is because there is less tax to foreign government, therefore there is a bigger profit for the manufacturers. Because LEDCs have a weak economy, there are very few
Other factors can include Gutters and Drains quickly taking water to the rivers. Pakistan however does not suffer from this problem as they have a low economical climate which lead then to have dirt roads for example. Although Pakistan has little economic activity this has spurred them to cultivate and gather resources such as using the surrounding trees to use for biomass (energy). Economic impacts in Cumbria (MEDC) will be higher than Pakistan (LEDC) due to the high value buildings and infrastructure. However the relative economic impacts will be lower for Cumbria and higher for Pakistan.
In the U.S., the storm drain system (it is connected to the drain of gutters, driveways, and streets) is usually separated from the sanitary sewer drain system (connected to toilet and sink, for example) which deals with pollutants. Thus, storm water flows directly into water streams. Even if the storm water drain system is connected to treatment plants, flooding causes storm water overflow. Impervious surfaces reduce the amount of water which seeps into the ground and
Water transport has less environmental impact than transportation by train and even less than transportation by road. Because transportation will be within 100 miles in a local eating community, road transport will be the only source of transport needed, therefore causing more pollution than if countries continued to import goods by boat or
Since the first manufacturer can produce the treated lumber without any additional input, they have absolute advantage over the other manufacturer and can be a price setter within the domestic market. The other manufacturer is limited by the amount of lumber it can purchase but has a better treatment facility so it cost less for them to treat their lumber. In this sense the second manufacturer has comparative advantage in producing treated lumber but their resources are limited by how much is harvested within the domestic market and thus they are price takers. However, suppose America opened trade relations with South America, a country with relatively low population density with desperate need for medical supplies and computer technology but covered with deep thick jungles. This new source of lumber is cheaper to harvest due to the massive quantities that allow the second manufacturer to stop buying the limited amount of lumber within its domestic market.
