Its Not Suction essays

It's Not Suction essays The purpose of this experiment is to show the effects that air pressure has on a liquid and the necessity of oxygen for combustion. When a substance burns it is known as combustion. For combustion to occur oxygen must be present. Once a flame has used all of its oxygen supply it will die, this marks the end of combustion. Combustion stops occurring when the flame supplying the energy to a system goes out or the substance is completely used up. In a closed system in which combustion occurs, all of the oxygen within that system is used. When this occurs the air pressure outside of the glass is greater than the air pressure within the glass because the oxygen has been used up. Even though some new gases are produced, there is still less air pressure inside of the glass than there was originally. During combustion, some of the gases inside of the glass are used, which means that the pressure within the glass is now lower than the pressure outside of the glass. Since the air pressure outside of the glass is greater than that of the air pressure within the glass, the water level inside of the glass will rise. The water within the glass rises because the external pressure pushes down on the water with a greater force than the internal pressure does. Suction does not occur during this process because the force from the external pressure pushes the liquid into the glass. There is nothing inside of the glass pulling the liquid upward. - Melt a little wax and drip into the middle of the saucer. - Place the end of the candle into the wax and allow to harden. - Put 30 50 ml of water into the saucer. - Place the glass over the candle and onto the saucer. ...

An offer can be made in oral form, written form or conduct

An offer can be made in oral form, written form or conduct Disclaimer: This work has been submitted by a student. This is not an example of the work produced by our Law Essay Writing Service . You can view samples of our professional work here . An offer can be made in oral form, written form or conduct Question: How is an offer terminated? Please provide examples and case law in order to support your answer. Offer, Acceptance and Consideration are the three main components to form a legally binding contract. And before any contracts are being made, there must be reasonable and proper means of communication between parties. An offer is a definite and specific promise made by the offeror to an offeree of which there is an intention to be bound on specific terms if it is accepted. An offer can be made in oral form, writing form or by conduct, noted that it should not be vague but definite. In order to terminate an offer, there are five ways to do so which will be shown below: 1. Rejection There are two forms of rejection to an offer. The first form is that the offer is simply rejected by the offeree for not willing to be bound by the terms of the offer through communication, this will permanently destroy the offer. The offere e cannot change his/her mind afterwards and purport to accept the offer again. For example, Jean wanted to buy Peter’s car and offered him a price of $32,000. Peter then replied to say that $32,000 was below his expectation. In this case, Peter had rejected Jean’s offer and the offer no longer existed. Therefore, Peter could not change his mind and tell Jean that it was a mistake not to accept the offer. But then he can now sell the car to Jean by making a new offer, and Jean is free to accept it, contract will therefore formed. The second form of rejection to an offer is that the offeree rejects the offer made to him/her by a counter offer. This counter offer will destroy the original offer and introduces a new offer. In this case the original offeror may accept or deny this new offer. According to Hyde v Wrench (1840), where â€Å"A†, the offeror offered to sell an estate at a price of 1000 pounds, â€Å"B†, the offeror replied that he was willing to pa y 950 pounds only. The offer was refused, but afterwards, â€Å"B† sought to accept the initial offer. It was held that the offer has already terminated by the counter offer of 950 pounds, therefore no contract could be made at the time â€Å"B† tried to accept the initial offer as it no longer existed. However, it should be noted that a mere inquiry about the terms of offer to make the bargain more favourable, while he is willing to accept the offer is not a counter offer nor rejecting the offer. This principle lied in Stevenson v. McLean (1880), where â€Å"A† offered to sell iron to â€Å"B† for cash. â€Å"B asked if they could have 4 months credit. He has no intention to reject the offer made to him. 2. Revocation The offeror is free to withdraw or revoke from an offer at anytime given that the offer has not been accepted by the offeree. Given that revocation will not be effective until it is communicated to the offeree. Communication is not necessa rily made by the offeror himself provided that the offeree has been brought to notice of the revocation through a reliable source.

Early Jazz and Society New Orleans & Chicago Assignment

Early Jazz and Society New Orleans & Chicago - Assignment Example The reason here is the fact that many conservatives first viewed jazz as a genre of music associated with dirty life practices such as prostitution among others. Second, â€Å"The secretary of the United States Navy ordered the closing of prostitution, gambling places, saloons and dance halls in 1917 across Storyville district of New Orleans.† This made other jazz musicians to look for work in other places. Further discrimination ensured that blacks migrated to other areas yet they were the majority customers for jazz musicians. Louis Armstrong later settled in Chicago becoming the pioneer of jazz music alongside other native Chicago jazz musicians. Lastly, â€Å"Radio stations generally boycotted jazz and blues music, but enough percolated through the air waves to increase the cult status of jazz. However, it was the record that contributed to the spread of jazz among white audience (Scarufi, P.).†Ã‚   In fact, jazz in Chicago is believed to have flourished owing to th e demise of the genre in New Orleans. Clearly, the behavior by radio stations shows a sense of sabotage to a genre already flourishing in many parts of the United States especially, Chicago and New Orleans. Arguably, this indicates how much skeptical the conservatives were about the existence of jazz music. Therefore, it is clear that jazz music in both New Orleans and Chicago faced a lot of resistance by the conservative public. Nevertheless, the genre managed to percolate and is now one of United States’ most loved music types.

Technology Evaluation and Recommendation - Essay Example Threats on their part can take up multiple flavors ranging from sabotage, deliberate espionage, leakage, or information extortion. As is evident with the virility of information technology as the contemporary means of capturing and storing information, it is important that access control systems should exist to protect information and information technology systems. Access control is one of the most sensitive aspects when it comes to computer and computer systems’ security. Access control refers to any mechanism that controls or provides a form of verification to guarantee information’s protection from inappropriate access or unauthorized use. Collectively, access control methods serve two purposes; controlling modification, and controlling the disclosure of information from threats. In computer security, a threat is any agent that may breach the confidentiality or interfere with the integrity of information or information systems. Threats on their part can take up multiple flavors ranging from sabotage, deliberate espionage, leakage, or information extortion. As is evident with the virility of information technology as the contemporary means of capturing and storing information, it is important that access control systems should exist to protect information and information technology systems. Social engineering occurs when a user is manipulated to trick a person into weakening a component of the system itself. One of the biggest dilemmas with social engineering is the fact that a hacker can obtain critical information via personnel relationships. This can be chaotic and cause many in adverse issues. Another method that plagues the dilemma of social engineering is pretexting. Pretexting occurs when a hacker calls an IT personnel for instance and give scenarios that will allow a hacker to have a perception for hacking. Another risk that seems to be prevalent in user domain accounts that correlated with human mistakes is the fact that it

Stellar Evolution Essay -- physics space stellar evolution

In astronomy, stellar evolution refers to the changes which stars undergo during their lifetime. Stars change in color, luminosity, size and temperature through their lifespan. Scientist can not study an individual stars lifetime though because they far exceed ours and therefore we must study stellar evolution by observing the life cycle of numerous stars, each at a different point in its life cycle, and then running computer models which simulate the structure of stars. Through history stars have been recorded, starting with the brightest, which have been named going back as far as 1000 b.c. by the chinese. Today we name stars in three categories, the first being the brightest are named for what constellation they are in. Variable stars are the ones that change in luminosity periodically and the fainter stars are logged in the Henry Draper Catalogue under numubers like HD 12938. Stars exist either alone or in groups of two or more in a system or cluster. Large clusters are grouped into galaxies and in our Galaxy, the Milky Way there are more than 100 billion stars. There are also 10's of millions of galaxies that are part of the known universe. Think about that and tell me there's no life out there. As technology permitted it was found that stars positions are not fixed and that stars move at various speeds measured in changes of direction in fractions of a second of arc per year. This second of arc is the angular size of a pinhead that is 183 m away (wow, now thats precise, you would think). Many of the fainter stars almost seem to not move at all though because they are so far away and thats why we use them as reference stars to measure others and scientists call this proper motion. A Parallex is another apparent m... ...rs of a fraction of a second. Its neutrinos send a shockwave out blasting most of the stars materials into space, but many of the elements get caught up in neutrinos and combine to create heavier elements. Without supernovae there would be no heavier elements than Iron-56. It is not understood well, but in some supernovae the gravity is so intense within the red supergiant that the electrons are forced into the atomic nuclei where they combine with protons to form neutrons. The electromagnetic forces keeping apart the seperate nuclei are gone and the entire core becomes a dense ball of neutrons or an atomic nucleus about the size of Manhatten called a Neutron Star. If the mass is great enough though, when the star turns into a red supergiant it will collapse under its on gravity into a radius smaller than the Schwarzchild Radius and turn into a Black Hole.

Monetary Policy of Bernanke

Ben Bernanke is current Chairmen of US Federal Reserve and his task is to ensure appropriate monetary policy in order to improve country’s economic and financial performance. Bernanke argues he has to work closely with all members of the Committee because it is the only way to develop monetary policy in such a way that it would fit country’s needs and demands. Therefore, the paper discusses issues of monetary policy offered by Bernanke as well as examines influence of globalization on overall monetary policy of the country. Actually, Bernanke is interested whether ongoing economic globalization and integration affects US monetary policy. Monetary policy operates in financial and economic environment being strongly affected by integration. Bernanke notes that monetary policy instead of stabilizing economic and financial situation in the country does little to drive powerful economic forces and to cause structural changes necessary for policy. Bernanke claims that if Federal Reserve wants to develop effective monetary policy, it should, firstly, be fully aware of all factors which are able to affect and determine the overall economic growth, inflation and employments rates in the United States. Chairman asserts that country’s economy should be open to other countries because openness plays crucial role in monetary policy affecting price stability and sustainable employment within country. Furthermore, economic openness also assists Federal Reserve in meeting congressional mandate. Bernanke cites analysts who argue that globalization puts obstacles to US monetary policy because it aims at reducing US interest rates of Federal Reserve and asset price. Also globalization diminishes the role of domestic factors affecting inflation process. Nevertheless, Bernanke doesn’t support such idea claiming that he is sure globalization should be implicated to increase effectiveness of monetary policy. Globalization and Monetary Institute was established to study impact of globalization no economy and policy of the country. Bernanke argues that monetary policy affects above all country’s financial conditions and asset prices and interest rates are under attack. Consequently, changes taken place in financial conditions would affect many households and firms, as well as would affect production, consumption and investment opportunities. Thus, Bernanke states that â€Å"the financial environment in which U.S. monetary policy is made has been irrevocably changed by the remarkable increases in the magnitudes of financial flows into and out of the United States†. (Bernanke 2007) Therefore, he argues that he Federal Reserve should pay more attention to financial stability by controlling federal funds and interest rates. Banks loans should be carefully considered as well. He recommends using open-market operations because due to policy of openness the Federal Reserve would be able to manage constant supply of funds, inter-bank markets. Such policy will keep federal funds close to the targeted rates and international integration of financial markets will not be affected or prevented. Further, Bernanke admits that the Federal Reserve should take proper control over the federal funds rates because they strongly affect short-term dollar nominal interest rates. Bernanke promotes cooperation of the Federal Reserve with modern central banks because it gives excellent opportunity to conduct monetary policy, to examine economic and financial data obtained from variety of markets, and to apply those data when considering economy and inflation. Bernanke says it is necessary to seek for alternative courses of policy to improve effectiveness of monetary policy and macroeconomic performance of the country. He recommends developing economic models to guide policymakers and forecasting techniques to ensure sustainable progress. Bernanke assumes that â€Å"monetary policymakers must therefore strike a difficult balance –conducting rigorous analysis informed by sound economic theory and empirical methods while keeping an open mind about the many factors, including myriad global influences, at play in a dynamic modern economy like that of the United States†.
