Helicopter Experiment Essay Example for Free

Helicopter Experiment Essay Prediction: As the mass on the helicopter’s copters increases, the speed taken for the rotors to spin down faster, this is because there will be more downward pull from gravity, as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include, the helicopter itself. As well as the height from which the helicopter is released. Apparatus: Paper, Scotch tape, Scissors, Ruler Method: Create a helicopters rotors using take and paper use the diagram to help you Apparatus: 2 meter rulers, one stop watch, one balance, 3 paper clips, pencil. Method: 1) Using both the meter rulers and a pencil make a mark on the wall. 2) Weigh the helicopter then record its weight 3) Hold the paper helicopter parallel to the mark on the wall 4) At the same time release the helicopter and start the stopwatch 5) Stop the stop watch when the helicopter touches the ground 6) Weigh the first paper clip and record its weight 7) Attach the paper clip to helicopter and repeat the experiment 8) Weigh the second paper clip and record its weight 9) Attach the paper clip to helicopter and repeat the experiment 10) Weigh the final paper clip and record its weight 11) Attach the paper clip to helicopter and repeat the experiment Conclusion and Evaluation: In this experiment my prediction was right, therefore proving that the helicopter may reach its terminal velocity faster with higher mass meaning that the speed is greater therefore it allows the helicopter to reach the  ground faster if there is more mass. There are two major flaws in this experiment, the first being the height from which the helicopter is dropped, as it is held away from the mark of 2m therefore it would have inaccuracies of around 10cm this causes the experiment results to vary. Another flaw being the human reaction time, which is pretty slow and inconsistent, this therefore allows us to stop the stopwatches at the wrong time making the experiment inaccurate. If more time was available, a string could have been hung from the ceiling as a mark of height therefore allowing us to accurately drop the helicopter from the same height, rather than dropping it from an *estimated* 2m. The solution for the wrong human reaction time could be easily solved by the use of light gates. The liht gates could be placed on the floor, and when the helicopter lands, the light will be disrupted therefore allowing the sensor to accurately measure the time taken for the helicopter to reach the ground. The graph is showing us that the speed and mass of a helicopter are directly proportional as when mass increases so does speed. However the graph had not been a perfect straight line, this could have been caused by the two inaccuracies pointed out from the experiment

The Idealized Picture Of Women In Fashion Advertisements Marketing Essay

The Idealized Picture Of Women In Fashion Advertisements Marketing Essay RESEARCH AIM The aim of this dissertation is to research and analyse the idealized picture of women in fashion advertisements and to define the role of digital impact of transparency in fashion advertisements. Another aim is also to provide recommendations regarding the best way of portraying the women in fashion advertisements to increase the brand sales. BACKGROUND TO ISSUE Womens fashion advertisements in magazines, television and in digital media show the idealized image of women that can cause different females reaction to that to which belong for example doubt in self-esteem, perceiving attractiveness in themselves, general body dissatisfaction or cause problem with eating. According to the range of researches womens self-perception changed through social comparison (Durkin, 2007). According to the WARC report We dont want to live in your fantasy world women want to see the advertisements that mirror their age, size or background. There is also a debate between many people how real women should look like in advertisements where the rise of digital technologies gives photographers, advertisers and other people who do advertisements opportunity to retouch images of models or celebrities. Most of the women are aware of the digital technologies and the way fashion magazines use them. Although digital technologies make air brushed models so popular, marketers have to know their potential customers needs and expectations towards the fashion advertisements. If consumers dont want to see air-brushed models in advertisements marketers have to respect this, otherwise there will be a loud respond in social media to that campaign. (Gillard, 2011). The subject will try to explain however fashion advertisements persuade or manipulate its target audience. It will also try to explain and evaluate a range of business and real-world marketing problems theories. Readers will learn and understand the effect of fashion advertisements on brand perception what is the impact of digital media in whole process of fashion advertisements and also how should look the future fashion campaigns to make its target audience happy.

Osmosis Investigation Essay -- GCSE Biology Osmosis Coursework

Osmosis Investigation How different concentrations of sucrose solution effect potato tissue. Aim How do different concentrations of sucrose solution effect potato tissue. Background Information Osmosis is the movement of water molecules though a partially permeable membrane from an area of high water potential to an area of low water potential. High Concentration Low Concentration The membrane lets small water molecules pass though but not large ones. The flow continues until the concentration becomes the same on the inside as on the outside. This is called equilibrium. Molarity is a measure of concentration. Prediction I predict that the potato will change in mass and in length. I believe this because each Molarity of sucrose will change the potato's water content. This will happen because either the concentration will higher in the sucrose and lower in the Tubas or lower in the sucrose and higher in the Tubers. Therefore water will travel in or out of the potatoes cell though its partial permeable membrane. Preliminary Method ÂÂ · I will firstly get 10 test tubes and to test tube racks ÂÂ · Then I will cut 9 pieces of potato ÂÂ · I will then get 3 different Concentrations of sucrose solution and add 20cm3 to each test tube ÂÂ · Cut a 4 mm in diameter tuba to 1 cm in length ÂÂ · Now I will measure the length and mass ÂÂ · Now place the pieces in ÂÂ · Now leave this for 15 minutes ÂÂ · Now I will measure the length and mass Preliminary Results After we did the Preliminary Test we decided to use 1 cm long 4 mm diameter tubas. We would put them in 25 cm3 sucrose solutions. I don't have any actual results because the potato tubas shrivelled up in the fridge. Method 1. I took two average sized ground potatoes and checked that they were both healthy and hard. 2. Using a standard kitchen knife I peeled the potatoes and used a potato tuba to cut 18 equally size tubas 3. Using a scalpel and ruler I cut the potato into lengths of 4mm by 10mm. I had to be very careful whilst cutting the potato as the scalpel is exceptionally sharp. I then had 18 tubas 4. Taking a test tube rack I placed 18 test tubes in it and then labelled them (0.00M, 0.25M, 0.50M, 1.00M, 1.50M, 2.00M) 5. Using a measuring cylinder I measured out 25cm3. I then poured this carefully into ea... ...the water potential inside the tissue. To measure the tubers I think I would use a digital measurer that goes to two decimal places for accuracy and it would go to the same accuracy level as the top pan balance. I would also increase the amount molar amounts I use, such as 0.25 and 0.75. one explanation for the bad results is when the potato chips were removed from the test tubes and dried I may well have dried some potatoes more thoroughly than others and so some would have more excess water, which would add to the mass. If the experiment was repeated I could find another way to dry the potatoes that would ensure that all were dried in the same way for the same time. I were to repeat the experiment I would have possibly found a machine to cut the potato as it would ensure that all potatoes would be the same weight and dimensions. As well as the potato I could have found a more accurate way to measure out the solutions and to determine the molar concentrations. Perhaps I could have used a burette. This would ensure that I have an accurate amount of fluid in each test tube. I could also weigh each tuber on a more accurate scale, e.g. not to 0.00g but to 0.0000g

Abortion :: essays research papers fc

Abortion is defined as the termination of pregnancy before the fetus is capable of independent life. Abortions must be conducted before the end off six months, or the fetus will leave the womb and it would be considered a premature birth.There are two types of abortions. One is spontaneous and the other is induced. If the fetus ways less than 18oz or is less than 20 weeks into the pregnancy, it is usually considered an abortion. Spontaneous abortions are known by another name, miscarriages. These usually occur during the first three months of pregnancy. It is estimated that 25% of all pregnancies end in spontaneous abortion.The second form of abortion is induced abortion. This is the deliberate termination of the fetus. There are four main types of induced abortions. The first takes place up to 12 weeks. It is called vacuum aspiration. This is where a tube attached to a vacuum is inserted into the uterus and sucks out the embryo and all other material. The second type takes place after the 15th week and is called saline infusion. Here, the doctors replace a little fluid with a salt solution. This causes the uterus to contract. The fetus is then expelled. The third type is a hysterotomy. This is a similar procedure to a cesarean section. The only difference is, in this operation, is that the cut is smaller and lower. The fourth type is available in the first fifty days. It is a drug called RU-486. It was developed in France and approved for sale there in 1988. Clinical trials in the United States began in 1994.When performed under proper conditions, the sooner the person has the baby, the less risk she is at. The likelihood of complications increase as the woman gets farther into the pregnancy. Although, an abortion has less of a risk of injury than does actually delivering the baby.Abortion is one topic that has been heavily debated. Many cases have gone to court over an abortion. Perhaps the most famous case was Roe vs. Wade. It was a case that was settled in 1973 under Justice Blackman. The Supreme Court ruled that they could not ban abortions in the first six months of the pregnancy. After six months, the states can ban an abortion except in cases in which the woman's health is at risk.I think that there is a lot that can be done.

Ethics & people Essay

The question of ethics is particularly important for a person who is both part of society and works with a group. The development of community and collective self is impossible without the struggle of opposing ideas and positions, and the collision of different points of views and opinions through which it is possible to overcome contradictions and disagreements. The relationship within a team works in a â€Å"mirror-system† where members can see their behavior reflected in their interaction with other people. An example of this can be seen when group members introduce themselves to each other. Usually, group members gauge how they will act depending on how the first person introducing will make them feel. If they feel comfortable with the personality of that person, they will also act naturally. However, if they feel threatened or intimidated, they will also exhibit signs of such. Understanding this particular group dynamic is important in maintaining relationships in the workplace. Once members understand this, they start to create their own group values/culture of which good ethics is a foundation. The presence of group ethics and values can lead to the success of a group especially in diffusing conflicts to maintain decorum and maintain work ethic (Green 2006). I want to point out an experience I had in which I acted unethically within a group. This instance happened last semester when I took a class in Entrepreneurship and got into an argument with a groupmate while planning for a project entitled â€Å"Blue Ocean Strategy†. I was trying to convince him that my side was right. I was on the verge of tears that I raised my voice and walked out on him, slamming the door as I left. In retrospect, I realized that I reacted unethically to the situation. Since I was part of a team, my actions disrupted the group and affected our work ethic. But what was I to do? Keep quiet even though I had a good suggestion for the group? Let my idea be discarded without me fighting for it? I have tried to justify my actions as a way for me to assert myself, to make my groupmate realize that I was trying to contribute to the group. This, however, did not change the fact that my outburst affected my group’s opinion of me. Now I understand that to act ethically is to act calmly in resolving conflicts. In defending my ideas, I have to be careful to exude confidence calmly and not arrogantly. Being aggressive and arrogant creates a negative feeling within the group. It is also important to choose words carefully when dragged into a conflict. It is even better if I keep my silence even if my groupmate is goading me. I should calm myself and wait for my partner to calm down too before we try and solve the problem. The Chinese philosopher Sun Tzu in his book The Art of War shared that it is best to win without fighting (Tzu 1). Thus, the real winner of any conflict is the one who is able to prevent it from the start. It is an important exercise to weigh factors first before getting into a conflict. â€Å"What have I got to gain? To lose? †, â€Å"Will these actions lead to a solution for the group or for myself? † These are the questions that I will ask myself before I confront any one, not just members of my group. Conflicts will always arise whenever people get together. What is important is how the group will move together to resolve such issues. Even though groups move in different contexts, whether political, social, industrial or domestic, the strategies to conflict management are grounded on one, same idea. We should always act and behave ethically and not let emotions seize our actions. Works Cited Green, Daryl. Understanding Group and Personal Ethics. Nu Leadership Series. 2006. EzineArticles. com.

Report writing on Communications Problems

Nikkei Meta highlighted the small things to be considered while communicating in a group or at personal level such as difference between observation and perception. As the course gradually moved on, professor introduced a case on communication problems in supply chain based industries in which the teams were asked to speak about the case and come to some conclusion. The main part was to present that case in front of the camera. My group got the first chance to present the case, and we were fortunate because we got know our natural skills to resent.After the presentation, professor Nikkei Meta, Assistant professor, National Institute of Industrial Engineering, Iambi threw the feedback to us highlighting our shortcomings. Later on we were asked to do the rehearsals as many times as possible before second video recording session. We rehearsed for 12 times to count the time and to check preparation level. Initial days we rehearsed for 60 minutes. As days were passing we had increased the duration of the speech from 60 seconds to 75 seconds,75 seconds to 90 seconds and later moved to 90 seconds to 120 seconds.We have filled the public speaking rubric form once in every alternative days when we had finished our practice. During rehearsals initially I thought my problem was speech appendages. But after rehearsals I found out the real weaknesses other than fillers which are long pauses, lower confidence levels in public speaking, nervousness. With the advice of team members worked on my weaknesses and reduced some of the mistakes through continuous rehearsals. It helped to improve my confidence levels , how to make draft so that long pause weakness can be minimized. In addition to that I improved my interpersonal skills.Later on we were asked to present the same case in front of camera to capture our improvements, preparation, and team coordination. To capitalize this opportunity, we followed a simple methodology. Before going for recording, we rehearsed for 3 times to count the time and to check preparation level. Also we could find the mistakes at the time of rehearsal only which benefited us not repeating the same while recording. We could observe the body language of each other and suggest improvements. Once we had done with our recording, it was shown in the class. Professor critically examined y moments in the presentation with our natural response.He commented on our individual performance as well as entire team highlighting the hand movements, voice modulation, rush delivery, etc. For further improvements sir gave us one more chance for recording. This time, we gone more prepared and we were more confident. For the second time, recording process was much smoother as compared to first time. We analyzed the second recording in a group and compared it against first recording. We could notice many improvements over the last recording on which we worked regularly, but still there is scope for improvements for each one of us.
