Mass Number Definition and Examples

Mass Number Definition and Examples Mass number is an  integer (whole number) equal to the sum of the number of protons and neutrons of an atomic nucleus. In other words, it is the sum of the number of nucleons in an atom. Mass number is often denoted using a capital letter A. Contrast this with the atomic number, which is simply the number of protons. Electrons are excluded from the mass number because their mass is so much smaller than that of protons and neutrons that they dont really affect the value. Examples 3717Cl has a mass number of 37. Its nucleus contains 17 protons and 20 neutrons. The mass number of carbon-13 is 13. When a number is given following an element name, this is its isotope, which basically states the mass number. To find the number of neutrons in an atom of the isotope, simply subtract the number of protons (atomic number). So, carbon-13 has 7 neutrons, because carbon has atomic number 6. Mass Defect Mass number only gives an estimate of isotope mass in atomic mass units (amu).The isotopic mass of carbon-12 is correct because the atomic mass unit is defined as 1/12 of the mass of this isotope. For other isotopes, mass is within about 0.1 amu of the mass number. The reason there is a difference is because of mass defect, which occurs because neutrons are slightly heavier than protons and because the nuclear binding energy is not constant between nuclei.

The Ethics of Lying

The Ethics of Lying Is lying ever morally permissible? While lying can be seen as a threat to civil society, there seem to be several instances in which lying seems the most intuitively moral option. Besides, if a sufficiently broad definition of lying is adopted, it seems utterly impossible to escape lies, either because of instances of self-deception or because of the social construction of our persona. Let’s look more closely into those matters. What lying is, first of all, is controversial. Recent discussion of the topic has identified four standard conditions for lying, but none of them seems to actually work. Keeping in mind the difficulties in providing an exact definition of lying, let’s start facing the foremost moral question regarding it: Should lying always be despised? A Threat to Civil Society? Lying has been seen as a threat to civil society by authors such as Kant. A society that tolerates lies – the argument goes – is a society in which trust is undermined and, with it, the sense of collectivity. In the United States, where lying is regarded as a major ethical and legal fault, the trust in government may well be greater than in Italy, where lying is far more tolerated. Machiavelli, among others, used to reflect on the importance of trust centuries ago. Yet, he also concluded that deceiving is, in some cases, the best option. How can that be? White Lies A first, less controversial sort of cases in which lying is tolerated includes so-called white lies. In some circumstances, it seems better to tell a small lie than having someone worrying unnecessarily, or becoming sad, or losing momentum. While actions of this sort seem hard to endorse from the standpoint of Kantian ethics, they provide one of the most clear-cut arguments in favor of Consequentialism. Lying for a Good Cause Famed objections to the Kantian absolute moral ban of lying, however, come also from the consideration of more dramatic scenarios. Here is one type of scenario. If by telling a lie to some Nazi soldiers during World War II, you could have saved someone’s life, without any other additional harm being inflicted, it seems that you ought to have lied. Or, consider the situation in which someone outraged, out of control, asks you where she can find an acquaintance of yours so that she can kill that acquaintance; you know where the acquaintance is and lying will help your friend calm down: should you tell the truth? Once you start thinking about it, there are plenty of circumstances where lying seems to be morally excusable. And, indeed, it is typically morally excused. Now, of course, there is a problem with this: who is to say whether the scenario excuses you from lying? Self-Deception There are plenty of circumstances in which humans seem to convince themselves of being excused from taking a certain course of action when, to the eyes of their peers, they actually are not. A good part of those scenarios may involve that phenomenon called self-deception. Lance Armstrong may have just provided one of the starkest cases of self-deception we can offer. Yet, who is to say that you are self-deceiving yourself? By wanting to judge the morality of lying, we may have led ourselves into one of the most difficult skeptical lands to traverse. Society as a Lie Not only lying may be seen as the outcome of self-deception, perhaps an involuntary outcome. Once we broaden our definition for what a lie may be, we come to see that lies are deep-seated in our society. Clothing, makeup, plastic surgeries, ceremonials: plenty of aspects of our culture are ways of masking how certain things would appear. Carnival is perhaps the festivity that best deals with this fundamental aspect of human existence. Before you condemn all lying, hence, think again.​ Source The Entry on the Definition of Lying and Deception at the Stanford Encyclopedia of Philosophy​.

Obesity Epidemic Its Link with Physical Inactivity and Lack of Research Paper

Obesity Epidemic Its Link with Physical Inactivity and Lack of Exercise - Research Paper Example This essay "Obesity Epidemic – Its Link with Physical Inactivity and Lack of Exercise" describes how inactivity or lack of exercise contributed to the obesity epidemic in our country. Surveys have shown that more than 1 in 3 Americans have excess body fat (Collins). Not only are the rates of obesity high but also are the amounts of physical inactivity and sedentary behavior. Data from CDC (2014) shows that in 2013, only 29% of children from high school had participated in physical activity for a minimum of 60 minutes per day on each of the seven days before the survey was conducted. The data also showed that about 15.2% students from high school had not participated in any kind of phsycial activity for 60 or more minutes on any day during the seven days prior to the survey. The CDC (2014) states that with age, the participation of young people in physical activity declines. Furthermore, its survey has shown that less than half of the students from high school attended physical education classes in an average week. Studies have shown that leisure activity and sports levels have remained stable worldwide but these leisure activities represent only a minor portion of the total levels of daily physical activity. The physical activity associated with transportation, home and work has reduced due to social changes, technological advancements and economic development (Harvard School of Public Health). While in 1950 in the USA, 30% Americans worked in occupations involving high activity, the percentage dropped to 22% in 2000.

Signal Cable Company Essay Example for Free

Signal Cable Company Essay Case 1: Signal cable company 1. Why has the stock price fallen despite the fact that the net income has increased? Ans: The stock price for Signal Cable company could have fallen for a variety of reasons. Stock price is influenced by the performance of the company, investor expectations as well as general market/economic conditions. In the case of Signal, it is clear that the stock price fell despite an increase in the net income. This could be possibly because the company might have made incorrect investment decisions by investing in two manufacturing plants as well tying up more money in inventory. Shareholders may not be happy with this decision and consequently the demand for the stock may have decreased causing a drop in price. In addition, the dividends offered by the firm has increased in 2004 from 0.187$ per share to 0.214$ per share. Once again, this could be indicative to the market of the company being uncertain of what to do with their resources and not having enough attractive investments to pursue. 2. How liquid would you say that this company is? Calculate the absolute liquidity of the firm. How does it compare with the previous year’s liquidity position? Ans: Short term solvency or the liquidity of a firm can be measured using the liquidity ratios. This is a measure of short term liquidity helping assess the sufficiency of current assets to meet current liabilities. The ratios include: i) Current Ratio: 2003= 2.50 2013= 2.06. The current ratio of the firm has decreased between the last 2 years. This is mainly driven by a huge increase in the inventory held by Signal Cable Company as well as an increase in the accounts receivables. This could be because creditors are not paying on or delays on the banking side. ii) Quick Ratio: 2004= 0.608

Chaucers Canterbury Tales Essay - The Strong Wife of Bath

The Strong Wife of Bath       Alison of Bath as a battered wife may seem all wrong, but her fifth husband, Jankyn, did torment her and knock her down, if not out, deafening her somewhat in the process. Nevertheless, the Wife of Bath got the upper hand in this marriage as she had done in the other four and as she would probably do in the sixth, which she declared herself ready to welcome. Alison certainly ranks high among women able to gain control over their mates.    The Wife of Bath's personality, philosophy of sexuality, and attitude toward sovereignty in marriage obviously are offered as comedy. When Chaucer's short poem addressed to Bukton, who is about to marry, recommends that he read the Wife of Bath regarding "The sorwe and wo that is in mariage" (ed. Benson, p. 655), he has to mean the domination, real or attempted, or the nagging, of the husband by the wife, that is sure to follow his wedding. Why else recommend the Wife of Bath for the edification of a bridegroom-to-be? And how could such an admonition be meant as anything but jest?    The Bukton piece leaves Chaucer's present-day audience wondering whether he and Philippa, married in 1366, had lived happily ever after. Unfortunately, the Chaucer Life-Records tell us nothing personal such as this. As for Chaucer himself, although he uses the autobiographical first person pronoun, his allusions to domineering and/or nagging wives are presented through the voices of his persona and of the pilgrim narrators of the Canterbury Tales, of whom the persona is one, all as likely to be fiction as to be fact. Chaucer remains inscrutable regarding his own marriage.    What, then, are we to make of the Bukton piece; of Alison of Bath and her anti-Pauline vi... ...st wife in the world. One would expect the married men hearing this to chuckle. But, needless to say, Chaucer's audience included women as well. In that day, when all marriage was Pauline at least in theory, and permanent sacramentally as well as legally, both "archwives" and "sklendre" had promised to obey. Women could join the laughter at this old chestnut because the shrew was some other woman. Of course good Christian wives never nagged their husbands.    Works Cited Chaucer, Geoffrey.
