Lemon Law

...the “burden of proof”? Support your answers. (75-100 words) (3 marks) I think there are tow points of aim. The first point is consumer protection. Consumers could be better protected against unfair business manufacturer accountability. The second point is to hold manufacturers accountable for the products that they produce and ensure that they will be safe to use by consumers. The Lemon Laws not only protect consumers from negligent manufacturers but also those that do make an effort but simply miss a problem while not in the market. The laws oblige manufacturers and dealers alike to have an appropriate response to consumer claims. (90 words) Question 3: What do you think are the practical problems that can arise in passing the Lemon Law? How do you think it can be managed? Support your answers. (250-400 words) (10 marks) Although the Lemon Law was taken effect in some countries on the world from many years ago, in Singapore, it has just been passed on March 9, 2012 and will come into effect in September this year. Certainly there are some problems can arise in passing of the Lemon Law. Firstly, there are many dishonest customers who try to seek repairs or replacement for a product that have become defective due to misuse or wear and tear. There have been instances where irresponsible customers buy winter clothing for a holiday and then seek a replacement when they return for something from the spring collection, claiming that a button has come off or the fur......

Lemon Laws

...Lemon Laws The Lemon Law applies to cars, motorcycles and other noncommercial vehicles that are used strictly for personal use. A lemon is considered a new car that has one or more problems that impair the use, value or safety of the vehicle. The problems must be occur in the first year or 18,000 miles whichever comes first. (ohioattorneygeneral) If the problems occur during this time you should take it back to the dealer you bought it from. If the problem is not fixed, you might qualify for a refund or replacement. Under the State and Federal law consumers have many legal rights as far as Lemon Laws. All 50 states have laws that will let customers return vehicles with major defects. (Soldiers Magazine 2003) One good way to know the condition of your car vehicle before you buy it is to get a Carfax. A Carfax report will give you valuable information about the vehicle before you purchase it. (Carfax) The report would include * Vehicle Registration * Title Information * Odometer Readings * Accident History * Damage * Repair Information * Recall Information Carfax Inc also offers a car buyback program if they give it a good report and you find problems after buying the car. If you want to request a refund you must first send a certified letter to the manufacturer. It must list the problems you have had with the car and what attempts you have taken to fix the problem. Once the manufacturer realizes the vehicle hasn’t been fixed there are a...

Batteries

...the Battery Could you imagine a world where every electronic device we owned has to be plugged into a wall socket in order for them to be able to be used and keep a charge? This would be very inconvenient. Mobility is important as well as very useful in our lives and therefore; it would only seem right that someone invented a way for our electronic devices to keep a charge without being constantly plugged into a socket. This man’s name was Alessandro Volta and he created the first battery in 1799, although there has been evidence of “clay pot” batteries dating back to 200 B.C. In order for an electronic device to be functional, electrical energy must be produced. In 1799, Physicist Alessandro Volta realized this reaction called “electrochemical reaction” is necessary in producing electrical energy and he was able to create the first battery by using an arrangement called the voltaic pile, in which he stacked alternating layers of zinc, brine-soaked pasteboard or cloth and sliver which created a steady, lasting current. This method has been improved throughout the years and is now made of many different materials and come in many different sizes and shapes. The next improvement on the battery did not come until 1836 when the Daniell cell was invented. This type of battery was invented by chemist John Frederick Daniell and was a way to power doorbells and telephones. In 1898, the battery called the Colombia Dry Cell was the first commercially used battery in......

...Final Investigatory Project for Group 5 I. Problems and Setting A. Introduction Batteries, years ago, have taken the world by a storm and have since than became a necessity in one’s household. Sadly, even though they are tremendously useful, batteries have drawbacks, such as semi- affordable costs, limited shelf life and pollution. Our group had an idea on how to make an alternative to this that would not only work like the real thing but would also be healthy to our environment and light in our pockets. This idea turned out to be realty and became the main goal of our Investigatory Project. B. Problems Finding an item that is easy to obtain and at the same time affordable, simple and earth- friendly is not an easy task. After a lot of thought, our group decided to use one of the objects that is almost always present in our daily lives: fruits and vegetables. Will these everyday materials such as apples, bananas, oranges, lemons and potatoes conduct electricity? Well, let’s see about that. C. Hypothesis A circuit is made up of a path, a source and a load. We believe that we should connect them with a (+) and a (-) wire so that the flow will be even with no reverse polarity. The load we thought of using was a battery- operated clock, one of the most common materials found in almost everyone’s household. We believe that it would work because the organic materials we will use have electrolytes that flow freely on its own. Thus, it will flow into conductors to......

Liquid Battery

...Homemade Batteries Homemade batteries are a popular subject with my readers. Making electricity from things you find around the house is a fun project. There are lots of easy ways to make homemade batteries. Basically, any two different kinds of metal can be placed in a conducting solution and you get a battery. Familiar homemade batteries include sticking copper and zinc strips into a lemon or a potato to make a battery. One quick battery is made from a soda can, the soda from the can, and some copper. Click on image for a larger picture The photo above shows a battery made by placing a strip of copper and a strip of aluminum into a glass of Coca-Cola (I used the sugar-free cherry flavored variety because that's what I found in the refrigerator). You can make the aluminum strip by cutting open the can. You will need some sandpaper to sand off the paint and plastic coating from the aluminum before using it. Or you can get strips of aluminum already free of coatings from a hardware store, or from our catalog. You can get copper flashing from a hardware store and cut out a strip of it, or you can use a bunch of copper wire (the more surface area exposed to the liquid, the more electrical current is produced). Or, as before, you can get pre-cut strips from our catalog. The aluminum-copper-coke battery will produce about three quarters of a volt. Click on image for a larger picture Using a zinc strip instead of the aluminum produces a little over a volt in the......

...acid, and wire. Even the hearts of our vice presidents are not free from the hidden enemy. Thousands die daily, but millions more take their places; they are silent, hidden from our eyes. Waiting for revenge. The battery rebellion is almost at hand, but it has been in the making for hundreds of years. While technically a battery is an energy storage system, most people refer to a battery as a chemical/electrical system, rather than any object with potential energy (a flywheel, a spring, a piece of firewood, or a bucket of water). Chemical electrical batteries work through a redox chemical reaction, short for reduction oxidation (the same reaction behind other tried and true human inventions like fire). Basically, an electrical current is generated when oxygen ions are mercilessly ripped from one molecule and forced upon another. A simple battery must then contain three things; two different materials (with contrasting oxidation potentials) and an electrolyte - the material which links the previous two and encourages the violent and unjust treatment of oxygen ions. You, the suspicious and disbelieving soul, can test this out by mercilessly sticking a lemon with a strip of copper and a strip of zinc. The copper and zinc are the anode and cathode, and the lemon juice is the electrolyte. Of course, if you don't happen to have separate strips of pure copper and zinc lying around your house, then you're probably not cool enough to understand the process anyway....

...know energy for providing us light and comfort. It can help us to cool down during summers and feel warm during winters. It also helps us to go from one place to another. There has been an enormous increase in the global demand for energy in recent years as a result of industrial development and population growth. Supply of energy is, therefore, far less than the actual demand. Wherefore, the great bottleneck in the supply of energy resources to an economy caused energy crisis. We all know that our world today is now facing energy crisis. Everyone is trying to do something and solve that about that problem. In this study, we can prove that electricity can be produced by vinegar. After all, vinegar is abundant everywhere. A battery is an electrochemical device that converts chemical energy to electrical energy. It contains thousands of charges (protons & electrons). It is also defined as a container consisting of one or more cells, in which chemical energy is converted into electricity and is used as a source of power. Likewise, vinegar is a liquid consisting mainly of acetic acid and water. It is produced from the fermentation of ethanol into acetic acid. The fermentation is carried out by bacteria. Because different metals have different levels of attraction for their electrons, one of the metals would lose electrons, a process which chemists call oxidation, and the other gains electrons, which is called reduction. The metal being oxidized is called the......

Battery

...The usage of "battery" to describe a group electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of cannon[2] (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together[3]). Alessandro Volta described the first electrochemical battery, the voltaic pile in 1800.[4] This was a stack of copper and zinc plates, separated by brine soaked paper disks, that could produce a steady current for a considerable length of time. Volta did not appreciate that the voltage was due to chemical reactions. He thought that his cells were an inexhaustible source of energy,[5] and that the associated corrosion effects at the electrodes were a mere nuisance, rather than an unavoidable consequence of their operation, as Michael Faraday showed in 1834.[6] Although early batteries were of great value for experimental purposes, in practice their voltages fluctuated and they could not provide a large current for a sustained period. The Daniell cell, invented in 1836 by British chemist John Frederic Daniell, was the first practical source of electricity, becoming an industry standard and seeing widespread adoption as a power source for electrical telegraph networks.[7] It consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode.[8] These wet cells used liquid electrolytes, which were......

Lemon Boots

...journey Lemon had through the post apocalyptic scenarios. The journey that she ventured on was that of trying to find herself in the world that had now become abstract. This made it difficult for her to find the person she was since she was, in a way, traveling through different era’s in society. The play crated a road map though the different eras by taking Lemon and the audience in a time travel warp starting from what technological world we live in today. This exemplified that Lemon was/is one of is and journeyed through the times as we, the audience, are living in now. Lemon finds herself trying to understand the effects of technology and the harm it has created on mankind. After the “apocalypse.” We can see that she was being eaten by some soft of dinosaur creature. Lemon seems to be in a state of trance where she doesn’t know her place in this ancient and almost mystical world. She tried to find shelter and tries to understand what is going on in the world she has been trapped in. Both of these experiences that Lemon go through are great examples of the meaning of the Lemon Boots. The audience witnesses that Lemon is not only confused of the tribulations going around her, she is also trying to understand her purpose in the multiple eras she’s traveling. In addition, the play seemed to have a paradigm shift where the time that Lemon is trapped in evolves into the world we live in today. Towards the end of the play we see the four different phases of lemon come......

The Lemon Orchard

...“Lemon Orchard” is a short story written by Alex La Guma, a South-African author, in the year 1962. The setting of this short story is in South Africa along two long, regular rows of trees, in a season of late winter, meaning it’s still a bit chilly in the air. It is late at night and there’s a big moon in the sky, it’s also a bit cloudy. It is probably set in the year that this story was written, while the big segregation in South Africa was still going on. The characters in “Lemon Orchard” is of a group of men, four of them mentioned in this story and their captive ‘colored’ man. There is the man with the small cycle lantern, a man who is the leader of the group carrying a loaded shotgun. All of the men in the party are warmly dressed, while there captive is the only one not wearing any thick clothes. This man is wearing trousers and a raincoat pulled over his pyjamas as if it was put on in a hurry. The action in this story is of these men walking through the night with their captive who they took because ‘colored’, probably referring to a man with a nationality of maybe Asian, South American etc. It is a racist way of calling a man, concerning his skin color. It doesn’t say exactly what happens to this man, but it kind of hints out that these men are here to beat this guy up, probably to his death, just because he has a different skin color. Also because he is an educated man who is a teacher. This is because in that time the people believed that men with darker skin...

... Servicing Lead Acid Battery Aizat Hizami Bin Abu Bakar, Unikl MIAT, aizathizami@gmail.com Abstract—These articles is about servicing one of the type of battery which is Lead Acid Battery. In time, batteries’ capacity may decrease due to the way we handle the battery thus proper way of servicing and charging of the battery is necessary. The capacity of the battery can be maintain through the process of servicing below. Index Terms—Battery I. INTRODUCTION O NE of the most important aspects of battery servicing is to keep the battery clean and all the terminals tight and free of corrosion. If any corrosion exists on the battery terminals or within the battery box, it should be removed. One way to do this is by scrubbing the battery box and the top of the battery with a soft bristle brush and a solution of sodium bicarbonate (baking soda) and water. When washing the top of the battery, avoid getting any baking soda in the cells since it neutralizes the electrolyte. After the battery and box are clean, rinse them with clean water and dry thoroughly. Coat the battery terminals with petroleum jelly or general purpose grease, and touch up any paint damage to the battery box or adjacent area with an acid-resistant paint. A lead acid battery goes through three life phases, called formatting, peak and decline are shown in Figure 1. Fig. 1. Cycle life of a battery In the formatting phase try to imagine sponge-like lead plates that are being exposed to a liquid.......
