Light intensity Essay Example for Free

Light intensity Essay The set up of the circuit is simple as shown above. The 12-volt lamp is set up in a simple circuit. Then in a SEPARATE circuit, the light dependent resistor is connected to the Multimeter, which shows the resistance readings. If I did connect the LDR in the same circuit, I would almost certainly fry the LDR, and ruin the experiment! I want to keep the distance from the lamp to the LDR the same. I have decided after testing the system, to put the LDR directly under the lamp. This makes me get the best readings for the earlier voltages when the bulb is dim. It also helps to cancel out any other light, which will obviously get in the way more, the further the LDR is from the bulb. I will find out how much this effects the results in the preliminary practical. I will needed to keep the bulb at a set height, perhaps 2cm above the LDR. During the preliminary practical, there are many things I can do to get the optimum results. That includes keeping the distance and height the same, but also taking the correct resistance reading. You can set the resistance readings on the Multimeter to different levels of accuracy. If you dont have a large enough setting, the dial will display one. I will then go down one until I get a suitable answer. I may even have to change the accuracy settings during the preliminary practical, if they become too inaccurate. My independent variable is voltage (potential difference). I will be finding out how the intensity of the light effects resistance of the LDR. I will be going up in gaps of 2 volts, up to 12 or 14 volts, giving me seven readings. I need to make sure I get two, preferably 3 sets of good results, to iron out anomalies, getting a better overall average. Some small errors could creep in when reading off the Multimeter. The resistance readings will start to fluctuate slightly. I will take the best reading I can by waiting until the Multimeter stays on one number. The more accurately I set the Multimeter, the harder this is to do. Of course, this is only an initial method. The preliminary practical will give me a good feel of the equipment, and where things could go wrong. I will be able to change things for the final practical. Preliminary Work I will need to undertake a preliminary practical for many reasons. A preliminary is very good for helping me get a feel for the equipment. I will do it to find out how much resistance there is without the lamp being turned on, to see what effect other light has on the LDR. I will also see if this changes when the LDR is out in the open. From this, I can decide where I will put the LDR in the final experiment. To start with, I will have the LDR directly under the lamp, so as little light as possible gets to the LDR. A second thing I will probably do, is slowly increasing the voltage until a noticeable difference is shown on the LDR. I will also get a good feeling of what I expect to happen in the actual main practical, and where I will be getting anomalous results. I may also be able to predict trends, and alter my graphs. I will only take readings at a few voltages. I may take readings at 4 volts (the lowest reading), 8 (a middle reading), and 12 (the highest reading. These are all of some use, as they will give me an estimate of the trends, and by finding the highest and lowest readings, the range. I will also need, in my preliminary practical, to take down the conditions that the practical is taken in. I will need to make the experiment as fair as possible, so I will need to see where all the extra light is coming from, so I can regulate that in my main experiment, and also things like the vertical distance from the LDR to the lamp.

Launching a Successful Digital Mobile Business Essay -- Apps for Busin

Introduction Since I was a child the idea of being a business owner has been a dream of mine. I never knew the requirements of starting, running or growing a business; however, I knew I needed to design a product to sell. In the 6th grade I approached my parents and told them when I grow up I want to own a business. I vividly remember my Father laughing while my Mother smiled and told me that it took a lot of work, time and experience to own and run a business. I decided to do some research, getting on the family computer I found out that a popular way to develop a business was to learn computer programming and write software. Years later, I worked in the Information Technology field after high school and saved up money to continue my education at State University. Majoring in Business with the Information Technology Concentration, I will gain the skills to work in a business environment but will still need to educate myself in order to found my own startup business. Taking Care of the Basics There are many markets, ideas and problems that have to be considered while brainstorming startup ideas. In fact there is such an abundance of aspects; one will undoubtedly feel overwhelmed from time to time. To avoid excessive frustration, it is a great idea to break up the development process into many different sections and complete each task in order. This paper will follow the path in which one should take in the development of their startup. The first task of a business is to decide on a product or service to develop. As stated above, there are many markets that can be considered in developing said product or service; however, I have chosen to stick to the market that is constantly growing and evolving on a day to d... ...portunity.

Democratic Society Essay

The conducted study revealed that both external and internal factors are of great importance for facilitation democratic changes in developing countries. Some observers argue that democratic outcomes are strongly related to the extent to which power holders have been encouraged by pressure from various external and domestic sources – for example, internationally, from foreign governments granting financial aid and, at home, from civil and political society to allow citizens greater participation in the political arena. Others suggest that democratic progress is primarily associated with an array of domestic factors affecting political outcomes, including level of economic development, quality of political leadership and political culture. It seems that truth, as usual, lies somewhere in between. Without a doubt, globalization of democratization encourages developing countries to keep up to date and join the process of internationalization of economic growth and get profit from widening of free markets, reinforced by new means of international communication. But our study proves that to promote democratization the developing nation has to maintain multiple domestic conditions such as adherence to sustainable economic development and willingness to allocate public resources in equitable manner, strong middle class, powerful and soundly structured civil society, effectively functioning multi-party system, and liberal political culture. Thus, economic development proved to be the most important predictor of democratization. It seems that, once a country achieves a certain degree of economic development, additional economic growth is an important ingredient for the developing country’s continued progress toward further democratization. Our study demonstrated that continued democratization of developing countries depends heavily on their economic liberalization, supported by the increased purchasing power of the people. The empirical findings cited in our study clearly showed that the ‘unique’ Confucian or Islamic political culture/civilization does not prevent the internationalization of national economies from affecting the degree of democracy. It seems, therefore, that states may be able to delay, but not negate, the process of political liberalization induced by economic liberalization. As the economic opportunities increase for individuals and private businesses, their awareness of the potential for improving their civil liberties also increases. Subsequently, they will begin to demand more freedom. It seems, therefore, that the improvement of the standard of living and the popular involvement in the economic and political decision-making are critical for long-term democratization in developing countries.

The Myth of Theseus Free Essay Example, 1500 words

Like Perseus, he too grew up without his father. Perseus and Theseus both proved their worth and their strength as heroes many times over through their battles; at one point, they even rescued their princesses from dark powers (Booker, pp. 276-277). Such similarities, as brave warriors, are seen in the heroic deeds of other Greek mythological heroes like Achilles, Jason, and Heracles. Like these heroes, Theseus also showed great strength and skill in battle. This is what made him stand out at a very early age, and what prompted his mother Aethra to reveal to him his noble heritage (Godwin, p. 252). This strength and skill helped him lift the rock which hid symbols and evidence of his heritage; it allowed him to survive many battles; it also allowed him to kill the Minotaur, and it eventually allowed him to rightfully claim his place as his father s heir while keeping his greedy cousins at bay (Warner, pp. 24-27). At the very core of his character, Theseus is a very honorable ma n as he always fought on the side of what was right and what was noble, even at great cost to his life. However, as a hero, he also possessed a tragic element to his character, and this element can largely be attributed to his bad qualities.

He can also be labeled as ungrateful when he abandoned Ariadne on an island, even after the latter helped him defeat the Minotaur (Garland, p. 204). Theseus also had an unhealthy appetite for women; he was renowned for his amorous affairs. The consequences of these affairs often proved to be unfortunate and disastrous. His abduction of the Amazon Antiope prompted the Amazons to invade Attica (Warner, p. 28). He, along with Peirithoos abducted Helen and Persephone.
