What Creates the Tides and Determines Their Timing

The gravitational pull of the moon and the sun creates tides on the earth. While tides are most commonly associated with oceans and large bodies of water, gravity creates tides in the atmosphere and even the lithosphere (the surface of the earth). The atmospheric tidal bulge extends far into space but the tidal bulge of the lithosphere is limited to approximately 12 inches (30 cm) twice a day. The moon, which is approximately 240,000 miles (386,240 km) from the earth, exerts a greater influence on the tides than does the sun, which sits 93 million miles (150 million km) from the earth. The strength of the suns gravity is 179 times that of the moons but the moon is responsible for 56% of the earths tidal energy while the sun claims responsibility for a mere 44% (due to the moons proximity but the suns much larger size). Due to the cyclic rotation of the earth and moon, the tidal cycle is 24 hours and 52 minutes long. During this time, any point on the earths surface experiences two high tides and two low tides. The tidal bulge that occurs during high tide in the world ocean follows the revolution of the moon, and the earth rotates eastward through the bulge once every 24 hours and 50 minutes. The water of the entire world ocean is pulled by the moons gravity. On the opposite side of the earth simultaneously there is a high tide due to the inertia of the ocean water and because the earth is being pulled toward the moon by its gravitational field yet the ocean water remains left behind. This creates a high tide on the side of the earth opposite the high tide caused by the direct pull of the moon. Points on the sides of the earth between the two tidal bulges experience low tide. The tidal cycle can begin with high tide. For 6 hours and 13 minutes after high tide, the tide recedes in what is known as ebb tide. 6 hours and 13 minutes following high tide is low tide. After low tide, the flood tide begins as the tide rises for the next 6 hours and 13 minutes until high tide occurs and the cycle begins again. Tides are most pronounced along the coastline of the oceans and in bays where tidal range (the difference in height between low tide and high tide) is increased due to the topography and other factors. The Bay of Fundy between Nova Scotia and New Brunswick in Canada experiences the worlds greatest tidal range of 50 feet (15.25 meters). This incredible range occurs two times ever 24 hours 52 minutes so every 12 hours and 26 minutes theres a single high tide and a low tide. Northwestern Australia is also home to very high tidal ranges of 35 feet (10.7 meters). Typical coastal tide range is 5 to 10 feet (1.5 to 3 meters). Large lakes also experience tides but the tidal range is often less than 2 inches (5 cm)! The Bay of Fundy tides are one of 30 locations worldwide where the power of tides can be harnessed to turn turbines to produce electricity. This requires tides greater than 16 feet (5 meters). In areas of higher than usual tides a tidal bore can often can be found. A tidal bore is a wall or wave of water that moves upstream (especially in a river) at the onset of high tide. When the sun, moon, and the earth are lined up, the sun and moon are exerting their strongest force together and tidal ranges are at their maximum. This is known as spring tide (spring tides are not named from the season but from spring forward) This occurs twice each month when the moon is full and new. In the first quarter and third quarter moon, the sun and moon are at a 45Â ° angle to each other and their gravitational energy is diminished. The lower than the normal tidal range that takes place at these times are called neap tides. Additionally, when the sun and moon are at perigee and are as close to the earth as they get, they exert a greater gravitational influence and produce greater tidal ranges. Alternatively, when the sun and moon as far as they get from the earth, known as apogee, tidal ranges are smaller. The knowledge of the height of tides, both low and high, is vital for many functions, including navigation, fishing, and the construction of coastal facilities.

The Socratic Citizen - 2050 Words

Assignment I: Is Socrates a good citizen? Discuss with reference to the Apology and the Crito. The Socratic Citizen Plato’s Socrates is a character plagued and prized with contradictions. He professed to care for nothing so much as virtue and human excellence but was incriminated by the greatest and most open democracy in ancient history. He was wrongfully convicted, yet unwilling to avoid his unjust execution. He is at once the most Athenian, citizenly, patriotic, and other-regarding of philosophers—and yet the most critical and self-regarding of Athenians. In exploring that contradiction, between â€Å"Socrates the loyal Athenian citizen† and â€Å"Socrates the philosophical critic of Athenian society,† Aristotle’s Politics comes to mind: â€Å"the†¦show more content†¦He presents himself as a human being of unparalleled piety and devotion who will risk life itself rather than abandon the duty that has been given to him. Socrates claims to be a selfless benefactor of the polis in that he had exhausted his private resources in the pursuit of the public good (23b-c, 30a, 31a-c). Because he does what is good for his fellow citizens for whom he feels regard despite the danger to which this exposes him, Socrates claims to be a benefactor of the Athenians. He refers with pride to his record of military service and underlines that it was service to the democracy: â€Å"When the commanders that you elected to command me stationed me at Potidaea and Amphipolis and Delion, I remained there like anyone else, and ran the risk of death† (28e). He is an honorable citizen who disregards death and preaches that â€Å"The difficulty, my friends, is not to avoid death, but to avoid unrighteousness; for that runs faster than death.† He has demonstrated that he is, by his own right, a patriotic citizen who cares deeply about the good of his polis and one who consistently acts in what he sees as his cityâ⠂¬â„¢s best interests; but he has also shown also that, in light of his own definition of patriotism, Socrates must be regarded as a uniquely patriotic Athenian.

Evolution of Cool-Roof Standards in the US

Question: Discuss the following points...Industry Analysis plus TrendsApartment plus condominium construction industryFactors which affect sizes of dissimilar elasticity of the demand for the houses? Answer: Industry Analysis plus Trends In wake of the economic recovery, some decreased vacancy also rates as well as lowers the rent prices that have facilitated development and growth in the complex starts. Additionally, declining the homeownership rates and aggressive lending to multifamily sector as well as gains within both employment as well as disposable income also have boosted the demand for apartments plus condominiums (Akbari Levinson, 2008). What industry comprises of: Apartment as well as industry for Condominium Construction is also primarily self-possessed of common contractors as well as construction management firms that also build multifamily sectors for varied range of dissimilar markets all across United States, also including the real estate investment firms, investors of individual property, developers of the real estate, tourism sector as well as federal plus state governments (Holden Kamenka, 1948). The industry also operators characteristically act as GC for the project, which also entails total planning plus organization of build-out, comprising of securing materials and also hiring subcontractors as well as complying with regional regulations. Apartment plus condominium construction industry: This industry actually comprises of common contractors accountable for the constructing novel multifamily units that are residential, including some high-rise apartments and also townhouses, condominiums as well as medium-till-high units i.e. units that are never separated from the ground-towards-roof wall ('How does advertising affect the price elasticity of lodging demand? Evidence from Taiwan', n.d.). Supply of the substitutes: If the supply of substitutes such as rented lodging decreases or descends then there exits a net augment in the demand for the houses plus vice versa. If supply of the rented house is less, also then there exists an enhancement in price and cost of the rented apartments. Thus, in long term people also find that this is cheaper and buying houses cost less than to own and live in any rented accommodation. Therefore, then these people tend to buy a house. Thus, they tend to increase the net demand of the houses (Lee Ha, 2013). Factors which affect sizes of dissimilar elasticity of the demand for the houses Responsiveness of quantity of the houses demanded towards change in the prices, income and also price of some other goods, and many more is even measured through corresponding elasticity which is Price elasticity for the demand of the houses, Income elasticity for demand of the houses, otherwise the Cross prices and its elasticity of the demand of the houses (Millichap, 2011). Demands for houses are increasing: With enhancement and development of more and more urban locations and growing demand of concrete the actual demand for houses are increasing and this has lead to growth in making of apartments and other big accommodations (Millichap, Stack Millichap, 2010). This even enhances the lifestyle of people staying thereby. This enhancement in demand will keep on growing with each passing year. Comparision: Baltimore Charlotte Baltimore employers of metro would later on add to the positions in government as well as education plus health services segment, drawing extra college-educated and also young workers that also seeks to the rent apartments within the live-work ecologies Charlottes developing the economy also has made this as an attractive aim and destination for some young professionals and also increasing the apartment demand as well as encouraging growth of the rent and also development of the same. Because novel residents actually enter market, developers that are optimistic as well as continue towards delivering the apartments, along with a proper focus upon the downtown Baltimore which is very close to entertainment hubs and universities, plus hospitals as well as some other vital employers. Though construction pipeline also thought of to become slow considerably from the last years increased pace, some three years of the elevated ending volumes would also push up the vacancy into low 5% range. Despite of the positive or optimistic demographic trends as well as public works also projects that would lift local economy, this city has slipped within NAI because of the job growth more or less below projected rate. This city slid a single spot in NAI all behind the high vacancy as well as below-average growth of the rent Employers in this city would increase the jobs by some 1.6 percent, also adding about 22,000 to the payrolls in the year 2015 Charlotte employers would also create some 22,000 jobs in the current year and also expanding the total employment to some 2.4 percent. Keeping speed with the housing demand, makers would also add some 2,150 units every year and lifting the supply by some 1.1 percent. After the delivery of 7,800 units in the last year, construction pipeline would then slow down considerably as some 4,600 rentals will be delivered in the current year.
