Physics-Inclined Plane Lab Essay Example

Physics-Inclined Plane Lab Paper If an object is placed upon a surface that is inclined at a certain angle then that will decide the acceleration in which the object is going down the inclined plane. When looking at an inclined plane it is important to see what forces are acting upon it to see what the object is doing. In our case of there was Fn, Gravitational Force and, Fd. These forces act upon the object to see where it is going. In an inclined plane there will always be at least two forces acting upon the object which would be weight (pointing downwards) and force normal (pointing forwards). Force normal as always been the opposite of the gravitational force, but that is not true because we now of horizontal planes, but this is a inclined plane and the truth is that Force Normal is always perpendicular to the surface the object is on. ength of Ramp: The length of the ramp was always constant as it was 100 cm. The length of the ramp never changed as the car always began accelerating for a total distance of 100 cm Distance of Motion Detector from Ramp: The distance of the motion detector and the ramp was about 40 cm. With there being 40 cm between the motion detector and the ramp the data that we collected could be extremely precise. The data would be precise and our acceleration would pin point. The only problem we had at the start was that it took time to set the motion detector to detect the car until we found the perfect place for the ramp to perceive the data. Coefficient of Friction: The coefficient of friction was taken away because of the equipment that we used.

Except for a few exceptions its is proved through our graph that the acceleration is increased as the angle is increased, but for those exceptions we may be able to say that error was involved as 30% is quite high. We found our data using two different methods and different numbers for each and generally got different answers. By looking at all of our data we can come to the conclusion that the angle of inclination does not affect the acceleration. Like our Projectile Motion lab that we have done recently the projectile went a certain distance at a certain angle and then after changing the angle the distance would decrease after a while. We can say the same for this Lab as that when the angle is lower than 90 the acceleration would increase until the angle is above 90 and the acceleration will decrease again. This is because if one looks at this problem it makes sense. The car will go much faster until the ramp if perpendicular to the ground and when you lower the ramp to 180i then the car will barely have any acceleration considering there is no friction. In our Lab we can calculate that there is about 32% error which is very high, but for several reasons is true. I believe that this 32% error was taken because of random and systemic errors meaning that what we did made the error much higher than it should be and also the fact that the instrument was a bit hard to work with. One random error was that we definitely did not collect data and that if we did collect more data the results would be much more precise then they are. Another Random Error was the time that we used, we may have not used the time to our best accomplishment as it took much time to prepare and also take all the data down. A Systemic error that occurred was with the frictionless car as the motion detector took a lot of time to detect the car and we had to measure at which height the car would be detected. This took several pre trails of which none were counted. Our results from which we got from the lab compared to the gsin? results were not that much different, however there were certain points that did not match up. From my overall look I can say that the design and method of the investigation was good. There were few weaknesses in the lab, such as the motion detector taking time to set up as well as getting it to work properly which may have increased the error. Another weakness was our time management which was not up to par, where in this case we were at times working to fast and rushing a lot as we didnt have much time left which affected our data greatly. Another weakness was when averaging the acceleration we only had constant acceleration for about 1 second in which we averaged those numbers together. The precision of the data was decent as our motion detector was quite accurate. For the few weaknesses I had I can say there are simple solutions for them to be avoided next time. With the motion detector I think we could first find a proper height for both the ramp and the car to be placed at and whenever we raised the ramp we would raise the motion detector by the same amount. Next was the time management where as always we could have stopped rushing and taken our time even though it was scarce, this was because we had to do this lab during a time with constraints. The last weakness was with the acceleration and my solution is to increase the length of the ramp and let the car run for more time and thus we will get a more detailed acceleration. To remove systemic/ random error next time we would have to make sure we have more time for the experiment and set up properly.

Data Integration at a Urban Multicultural Community College essay part 2

Data Integration at a Urban Multicultural Community College essay part 2 Data Integration at a Urban Multicultural Community College essay part 2 Data Integration at a Urban Multicultural Community College essay part 2Data Integration at a Urban Multicultural Community College essay part  1Furtehrmore, Powerfaids software and Jenzabar Software allow information sharing between students that will facilitate their interaction and learning, stimulate the development of team work and expand their experience of using the software. The interaction between students is important and, when they work on common projects that require funding, they need to coordinate their actions. In this regard, Powerfaids software and Jenzabar Software will help them to coordinate their actions accurately since the software is simple to use and allows users to share information easily (Garvin Artemis, 2007). Such information sharing between students contribute to the development of their new experience of working on projects in real life situations, counting on the available financial resources and developing projects respectively to the available re sources. In addition, Powerfaids software and Jenzabar Software helps students to share information and, thus, introduce changes or coordinate the budget of their project in the course of its implementation that frequently occurs on real world situations. This means that students acquire the valuable experience of sharing financial information using Powerfaids software and Jenzabar Software, while this specific software does not create any difficulties in students’ use. Instead, this software contributes to the development of the important experience, which students may use in their further life as well as in their professional development.In addition, Powerfaids software and Jenzabar Software allows data sharing between educators that may help them to coordinate their professional interaction and increase the effectiveness of their performance. In this regard, the information sharing between educator is also very important because they should understand, where the Institutio n is moving to and funding and financial operations can show them what the current position of the Institution is and what to expect from the Institution in the future. Moreover, they should also understand financial operations and resources available to the Institution to plan their own projects and plans to teach students using as much resources as the Institution can afford for their education. The interaction between educators also contributes to the better use of financial resources available to the Institution. For example, if educators plan some projects to implement during their courses, they should plan and asses their budget accurately. For this purpose, they need to coordinate their plans with each other. Otherwise, there is a risk that some educators will use the lion share of funds available for their projects, while others will get nothing. To prevent such unfair situation, the Institution should use Powerfaids software and Jenzabar Software, which allows educators to coordinate their plans and integrate them into the current financial policies of the Institution. In a long-run perspective, such interaction and data sharing between educators optimizes the financial performance of the Institution and helps to prevent possible financial difficulties, which the Institution faced before.Powerfaids software and Jenzabar Software and data securityThe data security is of the primary issues today and one of the main concerns of educators and students. In this regard, Powerfaids software and Jenzabar Software provide the high level of the data protection that can make students and educators certain in the data safety and information security (Chenhall, 2003). In actuality, the problem of the data security is very important because information breaches, especially in the field of finance may be very dangerous. For example, there are many cases, when banks suffered information breaches that resulted in financial losses because of the poor data protection. I n such a situation, educational institutions also need to enhance their information security to prevent similar problems. Even though risks are relatively low, compared to banks, for example, but still there is a threat of information breaches and unauthorized access to the database. This is why the Institution can use Powerfaids software and Jenzabar Software to decrease risks associated with information breaches since researchers (Gwynn, 2004) insist that this software has the high level of the data protection.Therefore, Powerfaids software and Jenzabar Software offers the multiple layers of the information security that protects data from the unauthorized access and minimizes the risk of information breaches. The protection of the database of the Institution and all the information that is stored or transmitted via its information system is crucial for the information security. However, some specialists (Littlejohn, 2002) insist that there is no ideal software that will protect u sers from information breaches or even identity theft. Even though, there is no ideal software, Powerfaids software and Jenzabar Software allows securing the target information through the complex system of encoding information and the system of authorization that controls the access of devices and users with their unique logins. Powerfaids software and Jenzabar Software provides the Institution with the basic set of information security but users should also remain aware of the fact that numerous risks and threats associated with information breaches cannot always be prevented without the use of special software and hardware.In addition, the Associate Director takes the full responsibility for the maintenance of the information security that means that the director will either appoint an IT professional responsible for the information security or outsource information security services from an IT company, although Powerfaids software and Jenzabar Software provide the high level of the information security. Moreover, suppliers of the software offer regular updates to keep the software up-to-date and protected from current information security threats. At this point, it is important to place emphasis on the fact that the free update of the software is a very valuable option because information threats keep progressing fast and without regular updates the existing system will be ineffective. However, updates will allow Powerfaids software and Jenzabar Software to function well and cope with new threats that emerge. In response to new threats, developers of the software should offer updates that will minimize risks and errors associated with information breaches that emerge and which have never existed before. This is why, while using Powerfaids software and Jenzabar Software, the Institution can count on reliable and stable performance of the software and minimal risks and threats to the information security. Alternatively, some researchers (Hart, 2004) suggest using Powerfaids software and Jenzabar Software in a combination with intranet and restriction of access to the software and hardware of the institution. Such protection is apparently useful and effective in the contemporary educational setting.Powerfaids software and Jenzabar Software as the effective data integrating toolTransparency of data is very important for the overall data integrity because, if some data remain unavailable to some stakeholders, then communication gaps can emerge that can deteriorate the atmosphere within the Institution. The concept of data integrity is crucial for the Institution, especially its financial department. The integrity implies that all data are clear and balanced. They are recorded and may be used easily. At the same time, integrity relies heavily on the transparency since it is the transparency that makes data really reliable and open for all stakeholders. However, this openness is not unlimited. Instead, its openness is the openness for users only. Many researchers (Garvin Artemis, 2007) argue that transparency is one of the main advantages of Powerfaids software and Jenzabar Software. In fact, often educational institutions become vulnerable to manipiulations and scheming with their funds. Such problems may emerge because of the low transparency of the financial system of those institutions. The transparency is virtually the major instrument that can prevent such manipulations and scheming. The transparency of Powerfaids software and Jenzabar Software helps the Institution to increase the confidence of stakeholders that improves the atmosphere and the organizational culture of the Institution along with the improvement of the quality of financial performance.Data Integration at a Urban Multicultural Community College essay part  3

Issuanc of sukuk and bonds in Malasiay Essay Example | Topics and Well Written Essays - 2750 words

Issuanc of sukuk and bonds in Malasiay - Essay Example The following discourse delves into Sukuk issuance with specific focus being on the Malaysian economy. According to Ayub (2009), Sukuk may be defined as certificates of equal value that represent an undivided interest in the ownership of an asset or investment. It should be noted that Sukuk have the benefit of being backed by assets hence they offer better protection to the investors as compared to the conventional bonds. Investors who require fixed investment return with low risk find Sukuk to be an ideal choice (Kuran, 2004). One of the forms of Sukuk is known as the Ijarah Sukuk. This kind of Sukuk is based on letting of property rights for a given property on an agreed price. Sovereign issuers have an inclination towards issuing Ijarah Sukuk on a sale and leaseback agreement for a given piece of real estate. The other type of Sukuk is known as Mudharabah Sukuk. This is essentially an agreement between the investors and managers of capital. These are investment Sukuk that represen t ownership of units with an equal value in equity. The holders of such Sukuks own shares and are entitled to the returns based upon the percentage of ownership. The key characteristic of Mudhabarah Sukuk is that the holder of the shares is not given a guarantee by the issuer on the capital and fixed profit but rather, the profit is based on a percentage of the given capital (Muhammad, 2009). Musyarakah Sukuk involves the contribution of capital by two parties to incorporate a common motivation. The issuer contributes a given amount of money to obtain a subscription of a given number of shares whilst the originator may contribute either capital or in kind. The profit is shared in a certain ratio and the losses are shared according to capital contribution. Sukuks known as Istisna’s are used to finance the purchase of a project item. The holder of the Sukuk offers finance for a given project and in turn obtains a title to the asset. The title can be returned to the developer at an agreed repayment methodology. It should be noted that Istisna’s Sukuk cannot be traded in the secondary market. Government bonds are issued by the government in order to finance the projects that they require. One of the key characteristic of government bonds is that they have a set maturity date. This implies that the issuer guarantees to give back the principal amount invested the bond after a certain period regardless of how the investment performs. Government bonds also have interest payments. The interest payment can be on a fixed rate whereby a fixed interest is paid periodically for the life of the bond or floating interest whereby the interest rate is determined periodically. The principal investment repayment is also a key characteristic of government bonds. According to Sharma (2007), â€Å"it is an obligation of the issuer to repay the principal amount in lump sum upon the maturity of the bond.†`p. 234. Some bonds also have a call feature whereby the iss uer has the liberty to return the bond before its maturity date and be paid a percentage of its principal amount. Once the callable bond is paid, the government stops paying interest on the bond. Government bonds are subject to a given minimum investment and have credit ratings. Bonds are income investment because the issuer pays a certain rate of interest for a given period of time until the bond
