Scientific Notation Operations Using Exponents

Scientists and engineers often work with very large or very small numbers, which are more easily expressed in exponential form or scientific notation. A classic chemistry example of a number written in scientific notation is Avogadros number (6.022 x 1023). Scientists commonly perform calculations using the speed of light (3.0 x 108 m/s). An example of a very small number is the electrical charge of an electron (1.602 x 10-19 Coulombs). You write a very large number in scientific notation by moving the decimal point to the left until only one digit remains to the left. The number of moves of the decimal point gives you the exponent, which is always positive for a big number. For example: 3,454,000 3.454 x 106 For very small numbers, you move the decimal point to the right until only one digit remains to the left of the decimal point. The number of moves to the right gives you a negative exponent: 0.0000005234 5.234 x 10-7 Addition Example Using Scientific Notation Addition and subtraction problems are handled the same way. Write the numbers to be added or subtracted in scientific notation.Add or subtract the first part of the numbers, leaving the exponent portion unchanged.Make sure your final answer is written in scientific notation. (1.1 x 103) (2.1 x 103) 3.2 x 103 Subtraction Example Using Scientific Notation (5.3 x 10-4) - (2.2 x 10-4) (5.3 - 1.2) x 10-4 3.1 x 10-4 Multiplication Example Using Scientific Notation You do not have to write numbers to be multiplied and divided so that they have the same exponents. You can multiply the first numbers in each expression and add the exponents of 10 for multiplication problems. (2.3 x 105)(5.0 x 10-12) When you multiply 2.3 and 5.3 you get 11.5. When you add the exponents you get 10-7. At this point, your answer is: 11.5 x 10-7 You want to express your answer in scientific notation, which has only one digit to the left of the decimal point, so the answer should be rewritten as: 1.15 x 10-6 Division Example Using Scientific Notation In division, you subtract the exponents of 10. (2.1 x 10-2) / (7.0 x 10-3) 0.3 x 101 3 Using Scientific Notation on Your Calculator Not all calculators can handle scientific notation, but you can perform scientific notation calculations easily on a scientific calculator. To enter in the numbers, look for a ^ button, which means raised to the power of or else yx or xy, which means y raised to the power x or x raised to the y, respectively. Another common button is 10x, which makes scientific notation easy. The way these button function depends on the brand of calculator, so youll need to either read the instructions or else test the function. You will either press 10x and then enter your value for x or else you enter the x value and then press the 10x button. Test this with a number you know, to get the hang of it. Also remember not all calculators follow the order of operations, where multiplication and division are performed before addition and subtraction. If your calculator has parentheses, its a good idea to use them to make certain the calculation is carried out correctly.

The Devil’s Harvest Essay - 2832 Words

Cannabis. It’s been called everything from â€Å"Weed from the Devil’s Garden† to â€Å"the happy little herb†. Cannabis, which is also called Marijuana, has a known history that dates back over 10,000 years. The oldest remnant of the industry of mankind is a little piece of hemp cloth/fabric that dates back to around 8,000 B.C. (website, HIA: Resources: Education: FAQs Facts: Facts). Cannabis was used by almost every ancient civilization for, but not limited to, ropes, clothing, medicine, and recreation. Marijuana has only been illegal for the past 73 years.

At this point, infamous yellow-journalist William Randolph Hearst had already invested millions of dollars into the timber industry for paper for his magazines. Whil e durable and quality paper made from hemp fiber was being efficiently processed using the decorticator, the timber industry was doomed for failure. This would have meant that Hearst’s major investments in the timber industry would have been ultimately superfluous and wasted. So to prevent this from happening, Hearst did what he did best. Smear campaigns. In 1937, Hearst teamed up with Commissioner of the Federal Bureau of Narcotics (FBN), Harry J. Anslinger, to spark a nation-wide smear campaign against Cannabis known widely as â€Å"Reefer Madness†. Cannabis was never really referred to as â€Å"marijuana† because marijuana is a type of wild mexican tobacco, a completely different plant. Hearst and Anslinger added a mexican name to Cannabis to make it’s image as a mexican product more easily hated by the American public. This campaign depicted african-americans and mexican immigrants as beasts who, when and after smoking marijuana, would seek to rape wh ite women.

Advertising Analysis Free Essays

Advertisements often find ways to sell their products by psychologically manipulating people. The advertising industry makes us envious of others and convinces us to be unhappy with what we have (Valko). Steve Madden ads usually feature women with absurdly large heads and hourglass bodies which try to force the audience to wonder what the ad is about. We will write a custom essay sample on Advertising Analysis or any similar topic only for you Order Now One of these odd ads appears in the March/April 2001 issue of Twist Magazine. It features a young woman with a big head helplessly running, as an airplane zooms over her at an abandoned airport. There are three characteristics within the ad that contribute the whole idea that Steve Madden shoes, clothes and accessories will improve your self image. The main purpose of Steve Madden ads is to suggest to its viewers that they will feel good about themselves by wearing his products. The model’s big head conveys self-esteem and self-pride and she challenges the consumer to look as good as she does. The young woman wears a face of apprehension and is running away from her old self to start her new confident life with Steve Madden products. The sleek black leather jacket on top of a sexy white shirt, short enough to reveal her stomach and curvaceous hips together with her tight low rider blue jeans, black pointy high boots, and trendy black bag complete her fashionable outfit. The embellished woman’s physique is aimed to appeal to women and girls between the ages of 16 through 25 in search of funky, hip, sexy clothes. Steve Madden likes to think of his clothes of as being distinctive and he illustrates his idea by setting an abandoned airport as the background for the ad. There is not a body in sight as the model runs across the old gum stained pavement. This calls attention to the idea that by wearing Steve Madden buyers isolate themselves from everyone else. She is too proud and conceited and cannot imagine being compared to anyone else. The Steve Madden logo in the ad also contributes to the main idea of the ad. It could have been anywhere on the page, why the sky. Steve Madden ads always have their logos imprinted on the sky to imply that the â€Å"sky is the limit† with Steve madden products (Liza). Steve Madden’s use of the airplane flying across the model’s head are to let his consumers know that the only thing to stop them from accomplishing the look they have in mind is the limit the set upon themselves. Steve Madden will help its buyers attain the appearance they have always envisioned. Furthermore, it can be said, in Bertrand Russell’s words that â€Å"Good advertisements will either make the audience envious of the lifestyle being advertised, or will generate within the audience the desire to be envied by others† (Harris). Many advertisers aren’t as successful but Steve Madden manages to persuade his buyers to buy his products through his eccentric ads. How to cite Advertising Analysis, Essay examples

Bignell Jonathan Essay Example For Students

Bignell Jonathan Essay Most theorists of genre argue that generic norms and conventions are recognised and shared not only by theorists themselves, but also by audiences, readers and viewers (Neale Steve, Genre and Hollywood, 2000, p 54). Many theorists working on genre have argued about where genre categories had come from. These arguments discuss the factors of texts, production and audiences. Whether the texts in the narrative itself can be considered as naturally forming the genres, whether these categories are used by producers of programmes or if the categories are brought by audiences to the programmes they watch. Furthermore there is disagreement about whether the task of the theorist is to identify genres so that programmes can be evaluated, or whether the task is to describe how actual audiences make use of genre in their understanding of programmes. From an evaluative point of view, both television theorists and television fans might regard some programmes as transgressing the rules of genre and therefore evaluate these programmes as inferior (Rose, p 103). For example, fans of Battlestar Galactica regard some episodes as the real Battlestar Galactica and others as spoiled with irrelevant aspects such as soap opera or romance. By contrast, one might argue that programmes which contravene the boundaries of a genre are more important because the conventional rules of television genre are potentially engaging the audiences attention and therefore have a significant dimension. This dispute can be derived from the historical perception that genre applies most easily to mass-market popular culture texts, so the programmes that are within the boundaries of a genre can be seen as mechanically designed in some form. However, texts often participate in several genres at the same time as well as the fact that all texts contribute to genre to some extent. Genre can be about working against the genre conventions as well as with them, it is not only a way of attaching programmes down to one specific genre, but by exploring other notions and mixing the genres is what makes the programmes more enjoyable to watch and more interesting. The title sequences of programmes are sequences of signs which signify the boundaries between one part of the flow of television and those parts of the flow which precede and follow them (Holland Patricia, Television handbook, 1997 p78) In this respect, title sequences offer cues to viewers which enable them to identify the genre of a programme. The viewer will identify a programme in relation to its genre with the many different kinds of signs that a title sequence might contain. For example, showing the institutions such as parliament that are the creators of newsworthy events, the title sequence of news programmes often contain dramatic orchestral music and images representing the coverage of news events. But it is unusual for the components of programmes to go completely to a single genre. In news, for example, there are interviews between presenters and experts or officials that are coded in the same ways as interviews in sports programmes, say in comparison of BBC news and Match of the day live . The address to camera found in news programmes can also be seen in sports programmes, or quiz programmes. BBC news contains sequences of actuality footage accompanied by a voice-over, but similar sequences can be found in documentary, current affairs programmes, wildlife programmes and other factual genres. Although the content of news programmes is necessarily different in each programme because, by definition, the events in the news are new, the format of news programmes exhibits a strong degree of continuity. The separation of news programmes into separate items, the importance of the news presenter and reporters as a team which appears regularly in programmes, and the consistent use of settings such as the news studios, logos and graphics make todays news programme look very similar to yesterdays and tomorrows news. .u2b034130f5f1aa37f4f8ebb370876510 , .u2b034130f5f1aa37f4f8ebb370876510 .postImageUrl , .u2b034130f5f1aa37f4f8ebb370876510 .centered-text-area { min-height: 80px; position: relative; } .u2b034130f5f1aa37f4f8ebb370876510 , .u2b034130f5f1aa37f4f8ebb370876510:hover , .u2b034130f5f1aa37f4f8ebb370876510:visited , .u2b034130f5f1aa37f4f8ebb370876510:active { border:0!important; } .u2b034130f5f1aa37f4f8ebb370876510 .clearfix:after { content: ""; display: table; clear: both; } .u2b034130f5f1aa37f4f8ebb370876510 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u2b034130f5f1aa37f4f8ebb370876510:active , .u2b034130f5f1aa37f4f8ebb370876510:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u2b034130f5f1aa37f4f8ebb370876510 .centered-text-area { width: 100%; position: relative ; } .u2b034130f5f1aa37f4f8ebb370876510 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u2b034130f5f1aa37f4f8ebb370876510 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u2b034130f5f1aa37f4f8ebb370876510 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u2b034130f5f1aa37f4f8ebb370876510:hover .ctaButton { background-color: #34495E!important; } .u2b034130f5f1aa37f4f8ebb370876510 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u2b034130f5f1aa37f4f8ebb370876510 .u2b034130f5f1aa37f4f8ebb370876510-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u2b034130f5f1aa37f4f8ebb370876510:after { content: ""; display: block; clear: both; } READ: Poetry Analysis Buffet Etiquette EssayTelevision police series personalise law and order in the personas of detectives and policemen, as do other genre programmes such as hospital drama. One of the difficulties in the study of genre in television is identifying which features of programmes are unique to a particular genre, to the extent that these features could form a list enabling the critic to establish the boundaries of a genre. In the BBC police drama series The Cops (1998) there is a consistent group of main characters who seem at first to be relatively conventional. Indeed, the programmes title is likely to trigger viewers generic knowledge of other television police series and set up a pattern of expectations. In the opening episode Mel, a young policewoman working with predominantly male colleagues, was introduced. Viewers also saw a young Asian policeman and a middle-aged veteran constable unhappy with the changes to policing, which he regarded with scepticism. These are familiar characters, and it is easy to see how storylines familiar in the police genre can develop around them. There could be tensions between Mel and her male colleagues, explorations of racism within the police institution itself and in the community which the Asian police officer deals with and conflicts between the middle-aged veteran, his younger colleagues and his superiors responsible for carrying out modern police policies. The members of the public with whom the police characters came most into conflict with were the inhabitants of a local housing estate and further storylines involving tensions between the police and the community offered conventional stories in the police genre. Problems of poverty, drugs, street crime and burglary, conflict between older and younger generations in the community and the difficult task of sustaining relationships between the police and people they grew up with while also enforcing law and order from the basis of the action in the episodes. But The Cops not only signalled conventional expectations of the police genre for the audience but also sought to manipulate these. The Cops was exciting television because of its negotiation with genre and the audience expectations which it mobilises.
