Physics Online Course Essay Example for Free

Physics Online Course Essay 1-How can you demonstrate that water is denser than ice without weighing them? What is the principle involved? Release an ice cube in water; the ice cube will float. The ice cube will displace some water as it â€Å"pushes† the water away. The principle involved is displacement. 2-The density of water is a maximum at 4 °C. Why is this property of water important for aquatic life? The maximum density being attained at   4 °C means that even if the water gets colder, the density will decrease. Therefore, ice (when it forms) floats instead of sinks. This makes the continuity of aquatic life during winter possible. 3-When two different materials are given the same amount of heat will their temperatures increase by the same amount? Explain with reasons? No. It depends on the ability of the materials to conduct heat. 4-It is generally observed that it is more difficult to cook food at high altitudes. Explain the possible reason for this? In higher altitudes, there is lower pressure. This means that water will not boil at 100 °C, but at a lower temperature, making your water not as hot as on sea-level, making cooking time longer. 5-What are the variable factors that affect the pitch (frequency) of a vibrating string? How are these factors controlled in a stringed musical instrument such as a violin? The speed and wavelength of the waves formed by striking an object. A musician controls the frequency through the strings tension and density, by pressing some of the strings. 6-If you want to see yourself fully in a plane mirror, the mirror needs to be only half your height. Draw a ray diagram showing how this is possible. Explain the diagram and principles you used. The image in the mirror looks as if the figure is far away, when in fact, it is right in front of the mirror. This is because the light received by the eye traveled in a straight line as if it came from behind the mirror. The mirror is also laterally inverted, meaning the figures right will appear as the mirror images left. References Leigh, J.R. (1988). Temperature measurement and control.

Abortion Should Remain Legal Essay example -- The Right to Life, Pro-Li

Abortion. This one word, or statement in this case, can be defined as death to some and as life to others. With two completely different explanations of a word, it is obvious that abortion is probably one of the leading topics of controversy in the world today. So, who will win the fight? The pro-choice supporters, or the pro-life supporters? It has been a battle since the first laws of abortion were enforced in the 1820’s. Neither parties are right, however neither is wrong. Abortion is a personal opinion that is conducted according to the personal reason. Honestly, although there are several people, pro-choice to be exact, that disagree, the question I ask is â€Å"Why should abortion be legal†? Isn’t it murder? Isn’t it taking a helpless souls life? In a case of an abortion, the child doesn’t stand a chance. It is unfair to the innocent and selfish of the one who makes the decision to abort the child. A legitimate reason can’t be found to take a life. When someone hits a motorist and kills them by car accident, they are prosecuted for involuntary manslaughter. These people serve time for the crime that they commit. Abortion only differs in one way; it is voluntary. The average punishment for voluntary manslaughter is life behind bars. If someone abuses a child to the point of death, they are prosecuted for homicide and will likely serve their entire life in prison. Abortion is the same as child abuse to the point of death. With legalized abortions, at the time that someone has the abortion, they hav e the procedure, and walk free and clear, several feeling no regret or guilt from their actions at all. They should have to pay for their selfish acts. The right to a legal abortion is allowing the mistake of pregnancy to become ... ...ose that are sexually assaulted. As for those that it is a personal choice to discontinue the pregnancy, I do not believe that it should be legal for personal reasons. There are thousands of people that are waiting to adopt newborns, therefore if there is not a health concern for the mother or the child, the abortion should not be allowed. I believe that this would teach our society to practice safe sex and to administer birth control more freely. So, abortion, legal or not legal? That is our question. Thinking critically, I believe that it is necessary to be a legal procedure only with limitations however. I also believe that it is the business of the pregnant women that is considering the abortion. Our society does not have a right to judge someone by the actions. Only God will judge us one day and he is the one for us to assure that we will do by his will.

Coffee and tea Essay

a. Drinking coffee and tea is a part of the daily life of adults and some of the young. Coffee which is made from Coffee beans and Tea which is made from tea leaves are often considered as helpful to our daily lives although tea is regarded as more healthy due to coffee having more Caffeine. However, they are technically both considered harmful to our health too. The pleasure of drinking coffee and tea excessively can have harmful effects to our health because of the Tannic Acid that is involved. Coffee beans that are grown in very high altitudes and mineral-rich soil often produce more acidity. The acid content also depends on the type and length of bean roasting and brewing method. Coffee’s pH averages about 5. 0 while tea (depending on what type) has a pH ranging from 4. 0 to 6. 0. The tea also becomes more bitter as the tea is steeped in the hot water. b. c. We love to drink coffee and tea because they satisfy and make us feel more awake. This is done because one part of their component is caffeine which helps us energize so that we could do the things that we do for longer periods of time. Not only that, Coffee and Tea are actually very helpful in preventing different kinds of diseases and cancers. Coffee can be beneficial because it can help prevent Alzeimer’s, Heart Disease, Type 2 Diabetes and etc. Not only do they help in preventing sickness but they also help us in exceeding our limitations like how coffee helps us improve our memory recall and how the different types of tea have different effect like Green tea which improves the cholesterol level and how Oolong tea promotes weight loss. However, by excessively or regularly drinking Coffee and Tea without giving care of what we ingest whether it be solid or liquid, we are just endangering ourselves to getting ulcer, stained teeth or maybe even worse; Esophageal cancer. To be able to help reduce the chances of falling into the harm of these beverages that we so love, we should always drink a cup of water after so that the acid that covers our teeth after drinking these beverages would mostly be washed off and so that the acids in our stomach would also get diluted and thus lessening the chances of our insides getting harmed. After drinking Coffee or Tea, we should always remember to never drink or eat anything sour shortly after because it will increase the chances of getting GERD which will cause heartburn and will lead to serious problems like Esophageal cancer later on if it is frequently experienced. To avoid the chances of experiencing these harmful side effects, we should not drink Coffee, Tea or other beverages with Tannic acid or others similar acidic ingredient on a regular basis.

Depending on the privacy issue, individuals could lose their jobs, and there also could be fines. The Massachusetts General Physicians Organization and the General Hospital Corporation agreed to a hefty fine to the government of U.S. due to breaching of patients privacy (U.S. Department of Human and Health Services, 2011). Such fines set a good example, thus ensuring health care facilities take caution in ensuring their staff members do not leak patient information. A disgruntled employee might also decide to use such websites to give confidential information about a patient in order to damage the patient’s reputation. A facility should have guidelines that will set the standards for instances like this and come up with harsh punishments if such an occurrence happens. Enforcing fines and harsh punishments to employees will highly reduce the chances of any leakage o f personal, patient information (Dimick, 2010). When any person receives information that is not meant for their eyes, they should report it immediately. Ethically, one should do the right thing and destroy what you have received. One should call and report, informing the organization what has happened.
