Carla Jones 11y set 1 Physics Investigation Essays Carla Jones 11y set 1 Physics Investigation Essay Carla Jones 11y set 1 Physics Investigation Essay Brief: A parachute manufacturer wants to find a suitable design for a parachute, which will let fragile scientific interments land safely. You must research and design ways of solving this problem. Having completed the practical you must make recommendations base d on your results.Factors that I could chose to investigate.There were many things that I could have chosen to investigate all of which I thought would make a difference to the fall, speed or landing of a parachute. These were :-* Surface area of the parachute,* Material used to make the parachute,* The Shape of the parachute,* The number of strings on the parachute,* The mass of the load attached to the parachute,* The weather conditions,* The height from which the parachute is dropped,* The surface the parachute and load land on and,* The length of the strings.* Surface area of the parachute.Basic informationBackground knowledge.Explanation of air resistance.An object that is falling through the atm osphere is subjected to two external forces. The first force is the gravitational force, which can be expressed as the weight of the object. In an equation for weight the weight can be defined as (W) which can be equal to the mass (m) of the object times the gravitational acceleration (g), (which is 9.8 meters per square second on the surface of the earth.)The gravitational acceleration decreases with the square of the distance from the centre of the earth. In the atmosphere, the motion of a falling object is opposed by the air resistance, or drag. The drag equation tells us that drag (D) is equal to a drag coefficient (Cd) times one half the air density (r) times the velocity (V) squared times a reference area (A) on which the drag coefficient is based.The motion of a falling object can be described by Newtons second law of motion, Force (F) = mass (m) times acceleration (a). Which can be written as (a = F / m). The external force is equal to the difference between the weight and t he drag forces (F = W D). The acceleration of the object then becomes a = (W D) / m . The drag force depends on the square of the velocity. So as the body accelerates its velocity (and the drag) will increase. It will reach a point where the drag is exactly equal to the weight. When drag is equal to weight, there is no net external force on the object, and the acceleration will become equal to zero. The object will then fall at a constant velocity. The constant velocity iscalled the terminal velocity.The following information was taken from a sky diving website and I have summarised the information give of the conditions they think best for skydiving. I think that it demonstrates how small changes could change the speed of the fall.Drag Co-efficient The best way to describe this is the thickness of the air. Wave your hand about in the air quickly not much resistance there. Now put your hand in a bathtub of water and try the same it is harder work. The water has a higher drag co- efficient than air. However, air does have a significant drag co-efficient too. Simply, the higher the drag, the slower speed things will fall at.Surface area: This is the main part on which drag takes place. The larger the surface area, the more drag is created, and the slower things will fall. E.g. Take a sheet of flat paper. Drop it, and watch it slowly fall. Now fold it in half twice and drop it again. Its the same paper, same weight, and same shape, just a smaller surface area you will notice how it falls faster. Larger surface area equatees to slower.Shape: Different shaped objects will to fall at different speeds. The basic rule is smooth rounded objects will fall faster than flat objects. Similarly, slower again we have shapes that cup or catch air.After looking at the options that are available to me and at the background information, I have decided to look at surface area for my investigation because I fell that this will give noticeable and reliable results and gaps betwe en the results collected.Prediction.I think that the larger the surface area of the parachute the longer it will take to fall a set distance. I think this because I know that as surface area increases so does friction, which will effect the speed at which the parachute will fall to the ground. I know that if you take a sheet of flat paper. Drop it, and watch it slowly fall. Now fold it in half twice and drop it again. Its the same paper, same weight, and same shape, just a smaller surface area you will notice how it falls faster. This happens because the surface area and therefore friction levels have been decreased as the paper was screwed up into a ball.ApparatusBlack bin bag cut into squares of the following areas500cm1000cm1500cm200cm2500cmWe used 50 cm of string tied op corners 100-500 sr 1200.851.02111 135 173free_ringtones_free_logos.comScisors selotapePen/pencil to mark black bin bag calculator.StringStop clock,Weight,Distance to drop parachute fromRulerDiagram.

Should You Explain a Bad Grade When Applying to College?

As most college-bound students know, the college application is a space for showing off. You want to put your absolute best foot forward to wow those college admissions committees. Sometimes, though, there are less than flattering aspects of your application that you simply can’t avoid. If you have received a less than stellar grade, you might be wondering how you should address it on your college application. If it’s on your transcript, it’s something that you definitely can’t hide. So, what should you do? In this post we’ll discuss the various scenarios in which you might explain a bad grade, and how you can go about doing so. If you’re wondering what to do about a blemish on your transcript, don’t miss our advice. It’s appropriate to address a bad grade on your transcript in a few different scenarios, but the common thread in each is that there is a perfectly good explanation for your bad grade. You may be a conscientious, hard working, intelligent student, but even the most perfect student might sometimes get a bad grade under extenuating circumstances. For example, if you went through significant personal changes, a family emergency, or another unavoidable event that had an impact on your academic work, you will definitely want to explain what happened. This includes things like a serious illness, the death of a family member, moving to a new school, or a similar, unavoidable event. Keep in mind that if you want to explain a bad grade and have your explanation bear any weight, it needs to be significantly different from your normal performance. If you have received a series of grades in the range of B- and C+, explaining a C or a C- won’t affect your application much. Instead, the bad grade or grades need to significantly differ from the grades you normally achieve. Explaining a C or C- will be much easier if you normally pull a perfect GPA. At the same time, the grades you’re explaining need to be an isolated event. If you get perfect grades during freshman year and then get sick during your sophomore year and get all Cs during the second semester, you’ll only be able to explain them if your grades go back up after your illness passes. If your blemish falls towards the end of your transcript and you don’t have time for it to reflect an improvement, you might even explain that you are now back on track and that the admissions committee can expect to see improvement on your second semester grades. If your grades suffer significantly due to an unavoidable event, and you are able to recover afterwards, there is a good chance that an admissions committee will be sympathetic to your explanation. Estimating your chance of getting into a college is not easy in today’s competitive environment. Thankfully, with our state-of-the-art software and data, we can analyze your academic and extracurricular profile and estimate your chances. Our profile analysis tool can also help you identify the improvement you need to make to enter your dream school. It’s important to remember that admissions committees literally see thousands of applications and they are familiar with a broad variety of personal circumstances. If your circumstances are not likely to stand out as extenuating or unusual, there’s no need to explain a bad grade. Sometimes they just happen, and trying to explain it as though it’s not your fault may come off as an unwillingness to accept personal responsibility. For example, if you normally receive grades in the B-range but during your junior year you fell in with the wrong crowd, put less time into studying, and got some grades in the lower-C range, you don’t have a very good excuse for the blemish on your transcript. Rather than trying to explain it, you should let your performance speak for itself and work extra hard to hit higher grades during your senior year. Similarly, there’s no reason to explain grades that aren’t significantly different from your normal achievements. If you are used to getting all Bs, but then get the flu and get an B- in geometry your sophomore year, the admissions committee probably doesn’t need to hear about it. After all, the grade is not much different from your usual performance, and getting the flu isn’t exactly a unique scenario to face in high school. If you are wondering if you should explain a bad grade on your transcript, ask yourself these questions first: If the answer to any of these questions is no, think carefully before explaining the blemish on your transcript. You may want to discuss your decision with a guidance counselor or teacher first to gain some more perspective. Don’t use your personal essay to explain a bad grade unless there is another reason for doing so. For example, if you experienced a traumatic car accident during your junior year and your grades suffered because of it, you should only discuss it in your personal statement if it was also personally significant in other ways. If you grew as a person, learned about yourself, or developed new perspective, you might address the accident in your personal essay. Then, your discussion of its impact on your grades has more context in the bigger picture. On the other hand, if the only reason you are addressing the accident on your application is because of its impact on your grades, you should include this elsewhere. There are probably more important things you could discuss in your personal statement. Instead, it’s usually best to address the extenuating circumstances behind a poor grade in the â€Å"Additional Information† part of your application.

Critically iscuss how Best Practice HRM Can Contribute to Improved Essay

Critically iscuss how Best Practice HRM Can Contribute to Improved Organisational Performance - Essay Example Following this, the discussion examines the link between HRM and enhanced organizational performance. The paper examines the arguments and evidence that HRM policies and practices aid in promoting higher levels of organizational performance and studies whether the advanced arguments are convincing. The constantly evolving business environment coupled with the growing competition fuelled by globalization demands adoption of an effective human resource practice, which avails the organization a competitive edge. Human leverage is a significant contributory factor in attaining competitive edge through customer satisfaction and organization performance. Over the years, interest has been building in the notion of â€Å"best practice† human resource management (HRM). The overriding idea hinges on the notion that a certain bundle of HR practices bears the potential to contribute to enhanced employee attitudes and behaviour, ultimately decreasing the degree of absenteeism and workforce turnover. In the last two decades, a number of publications have explored the links between HRM and performance (Guest et al 2003, p. 294). Organization performance encompasses indicators such as financial performance and excellence and productivity, as well as outcomes in aspects such as competence, commitment, and flexibility. Enhanced organizational performance refers to enhanced employees attitudes and behaviours, minimized degree of absenteeism and labour turnover and enhanced degree of productivity, quality and customer service (Armstrong 2012, p.56). Ultimately, enhanced organizational performance has the capability of generating higher levels of profitability. Literature Review Human resource management (HRM) deals with the personnel policies and managerial practices and systems that control the workforce. HRM details a strategic and coherent approach of an organization’s most dear assets-the employees, who personally and collectively add to the attainment of the org anization’s set objectives. Human resource correlate with business performance, especially â€Å"best or high performance† HRM practices, whose goals is to enhance employees’ abilities and motivation (Sturm 2007, p.3). Nevertheless, the correlation tends to be relatively minute in statistical terms, besides the fact that literature does not agree on the reason why, on implementation, some human resource practices fail. This raises a critical question as to whether human resource systems bear the capability to create a competitive edge by themselves, or they must be continued or reinforced by with other variables. Performance in the context of the organization applies and is synonymous with productivity, efficiency, effectiveness, and competitiveness. HRM theorists have attempted to establish a causal link between HRM and performance. High performance human resource practices bear a positive effect on organizational learning, which impacts positively on organizat ional performance. Nevertheless, it has been complicated to institute a direct linkage of human resource practices on business performance (Lopez, Peon and Ordas 2005, p.147). As a result, there has been growing interest in studies examining the potential contribution of effective human resource policy in aiding enhancement of organizational performance. This has made the impact of human resource management on performance an essential research issue in the field of HRM. Similarly, there has been a continual search

Mister Monday and Keys to the Kingdom Essay -- Garth Nix

Mister Monday and the keys to the Kingdom Mister Monday the first book in the series Keys to the Kingdom by Garth Nix, is a story about an asthmatic boy named Arthur Penhaligon, who is forced into an adventure of mystery, turmoil, and understanding. This all begins on a Monday, his first day at a new school. This is the day Arthur is visited by a strange man who goes by the name Mister Monday, and is handed a key that resembles the minute hand to an old fashioned clock and a strange book leaving him with the knowledge that he is supposed to die that day. When something happens between Monday and his butler Sneezer, Monday grabs Sneezer and they disappear leaving Arthur to think it was a hallucination from the asthma attack. Only to Arthurs dismay as when he awakes in the hospital the key and the book are with him. The book contains many examples of religious symbolism and references, particularly in Judeo-Christian traditions. The prime example is the affliction of each Morrow Day with one of the seven deadly sins that resu lts from their choice not to obey the Will. †¢ Mister Monday: Sloth †¢ Grim Tuesday: Greed †¢ Drowned Wednesday: Gluttony †¢ Sir Thursday: Wrath †¢ Lady Friday: Lust †¢ Superior Saturday: Envy †¢ Lord Sunday: Pride Also, each part of The Will embodied appears to hold a virtue.

There was a lot to like about the book and very little to dislike for me, as the main character reminded me of myself, and I enjoyed how everything ties together in the book. I enjoyed the plot and setting of the book and liked how there were clues through out the book on how things would happen, some more evident then others. The only thing I didn’t like about the book were thee items used in that fashion within the house. Although the author described everything very well in the book there were some things he left out or assumed the reader already knew. To me I didn’t get some of the items use but for a more educated people it could have been easy. Overall I had a great time reading the book and think others should read it to, in my opinion of course.

Design a computer system for a video hire shop Essay

I have noticed that keeping customer records on paper can be time consuming and neither practical or easy to use. The aim of this project is to create a database for a company or an organization; I have chosen Vinnie’s videos. My database will include customer information to make organization and customer relations simpler; the new system will be more practical. An electronic database will make life easier as it will be superior to a card filling system and will save time and money. A computer system is better than the old card filing method for many reasons. Example, searches can be carried out instantly rather than many manual records being waded through, customer information for a hundred people can be copied almost instantly to a standard letter. Vinny will be able to keep customer information lists, detailing contact information, stats on the customers videos, lists of regular jobs that need to be performed i. e. check who has videos out; in order that notices can be sent using mail merge. This will help Vinny keep up to data and on top of customer relations and business. A search function for my database will make it simple for letters detailing special offers which are customer specific to be sent out easily. After considering the pros and cons of the two systems I have decided that it is definitely more practical to use a computer system over a card filling system. Strengths and Weaknesses of current system: Vinny currently has a very primitive filling system, It has a lot weaknesses. It takes a long time to find records, as they are stored in a filling cabinet. When editing a record you must remove the entire card and rewrite it, it is time consuming to add new records. To re-sort the records would take a very long time as it would obviously have to be done manually. To search for information is also time consuming, especially if you are looking for a number of customers with similar records for some purpose. However the database is comprehensive and does contain all the records needed. What I need to do is design and makes a new database with all the information from the old one transferred into it. There are also a number of programs that I could consider using, they are Microsoft word, Microsoft excel or Microsoft access. I will need to use a database creation package like MS Access, Fox Pro, DBASE II or IV or Borland Database Explorer to create my database tables, queries, forms, reports and macros easily and also program them with the Visual Basic programming script to make my database into a professional running program. According to the user requirements MS Access is the best one also because it is mostly familiar to people. I will need a word processing package like MS Word, Notepad, WordPad and Word Perfect. MS Word is the best one to use because you can use word art and insert pictures or print screens into the document and also is mostly used by people. Hardware needed: I need a computer that can run Microsoft Access and Microsoft Word just in case I need to use the mail merge. For this I will use a QWERTY keyboard for the manual input of data and the commands for the computer. I will need a mouse or trackball to design the database forms, to navigate the GUI of the OS and to move copy and paste data. I will need to use a 31/2 inch floppy disk and drive or a CDRW disk and drive in order to save my database and to make backups of my database. I will only use a CDRW if the database exceeds 1. 38-1. 44 MB. CDRW’s can hold from 500-700 MB of information. I will need a printer to print out the design of my database of for word documentation of the database. The system should have at least 300 MHZ hard drive speed, and 5 GB memory, it should have at least a 128 MB RAM. Problem1: a system management to put the videos in order Form of output: a database Information to be output: video title, video director, main actor, year released, length and genre, how many copies are available and how many are on loan. Data needed to produce the output: video title, video director, main actor, year released, length and genre, which will be provided by Vinny. Desired outcomes and performance criteria: It has to be sorted so you can see a certain type of genre or year. Testing: To see if all the correct records are in the right query. Problem 2: needs a system to store all the members’ names and addresses Form of output: a database Information to be output: name, address, user number, telephone. Data needed to produce the output: name, address, user number, telephone. This is provided by Vinny. Desired outcomes and performance criteria: member’s details available so we can contact them if needed. Testing: not needed Problem 3: I don’t have a system to see who has what video checked out and who has videos that are over due. Form of output: database Information to be output: name, user number, video rented, date taken out, date due back Data needed to produce the output: name, user number, video rented, date taken out, date due back. This will be provided by Vinny, anyone that rents a new video will be entered into the database. Desired outcomes and performance criteria: a list to see which videos are on loan. When somebody rents a video out all I want to have to do is click on the film name and type their name in. The rental time allowance will be 3 days and automatically entered Testing: see if the people who have taken a video out have a book due on the database Analysis of Strategies for Backup and Security. The system will be backed up on CD-RW’s daily and on hard disk drives and a server. The database will have an encrypted modification password and it will be write-protected so it cannot be deleted. If a staff member needs to access the database to modify it, then a staff password is needed. It will not open until the password is correct Information Flow Error Checking To ensure that the information is correct the staff will send the members an invoice with their details they have inputted and attached is another form to fill in the correct information and then collect it and update the database. For the videos the staff will do daily checks on the database to see any obscure looking information in the database and will edit this info by getting the video and re-entering the video data again. Or the staff will do two copies of information identical to each other because the information will be inputted twice and if they are not identical then one or the other or both are changed with the correct information. Skills The user is a competent pc user and will not need any sort of training, he would like it to be user friendly though, so if any new staff join, it will be easy to pick up.

The Long Standing Effects On Children - 1495 Words

There are about three hundred million children that are subjected to violence, exploitation and abuse in orphanages (Kovacs Np.) Orphanages are supposed to be a haven for children to escape previous problems, but instead these institutions are homes of nightmares for children. For example, many children placed in orphanages are there to escape the abuse of families and loved ones, only to experience more abuse at the hands of the orphanage caregivers. In the United States, at least one-third of children admitted to infant orphanages younger than 12 months of age died, primarily of gastrointestinal and respiratory illness, often complicated by malnutrition (Humphreyes 625-634). This is not a problem in America, there are thousands of cases like this in countries such as China, Russia, Romania, and Africa, these countries are prohibiting children their happiness. Children have all the odds against them. They are being abused and neglected. Many of them do not even get adopted. Further more, there have been studies that show the long-standing effects of orphans in institutions after adoption. These institutions prevent child growth and development, most are inadequate for raising children, many children develop mental illnesses, and they do not give children the education they need to survive.
