1. Introdution:- When a car is speeding along at 50 Km per hour it has a tendency ('Inertia') to keep moving at the same speed and in the same direction unless some force acts on it. The car accelerates its occupants to its own speed so that they seem to be moving as a single unit. The inertia of the occupants is, however, independent of the inertia of the car. If the car were to crash into a tree, the force of the tree would bring the car to an abrupt halt. The speed of the occupants, however, would remain the same because of their independent inertia and they would bang into the steering wheel, the dashboard or the windshield. The force exerted by the steering wheel or the windshield would then bring the occupants to a stop but may in the process cause injury to vulnerable body parts such as the head and the face. Car manufacturers use 2 different restraint systems to help stop the occupants while doing as little damage to him or her as possible. The oldest one is the seatbelt that spreads this stopping force across sturdier parts of the body over a longer period of time to minimize damage. The air bag is the second and a more recently developed system that is used to deploying a rapidly inflating cushion in the space between the passenger and the steering wheel or dash board to prevent crash injuries.

2.History of Airbag:-
The car manufactures has spent a great time in advancing car safety features. The airbag is one innovative safety feature. Before the airbags that were placed in cars, the cars did not have any safety features. They had an automatic seatbelt. The car manufactures first introduced the airbag system in the 1970s. In 1971 the Ford Company tested the airbag system at an experimental fleet. Then a few years later the Chevrolet made the airbag in cars just for the governmental purposes. Later on General Motors…...

Plastic Bag Externalities

...Plastic Bag Externalities Audrey Lee ECO305 January 2, 2014 Positive Externalities The positive externalities of plastic bags include the ability to be recycled into other plastic products, lower transportation costs, helping to prevent contamination of hazards. Plastic bags have affected the economy by making the bags cheaper than other bags so they are more readily available. Plastic bags produces 70% less air pollution and 50 times less water pollution than in production than paper bags, and plastic bags require less energy to produce from start to finish; therefore less money is spent on cleaning up the pollution. Plastic bags have greatly helped to reduce the contamination in the health field by allowing healthcare workers to keep contaminated agents from spreading, thus lower the cost of healthcare this is especially helpful in third world countries. Negative Externalities The negative externalities of plastic bags include the following: most plastic bags end up in the landfills, oceans or as litter, all chemicals used to create plastic bags are toxic, plastic bags take 20 to 1000 years to decompose, and kill animals. One of the biggest plastic bag externalities is that plastic bags have a short use life, they are generally used for the short time from the store to home and then discarded. The discarded bags take 20 to 1000 years to decompose but most landfills today are not designed to decompose the products being put into them, so these......

...plastic bags to wrap customer purchases. You know that the traditional plastic bag takes about one thousand years to decompose (cbc.ca) and want to do your part to stop the proliferation of plastic bags in landfills. You feel that this is the kind of environmental action that will be popular with potential customers and a good opportunity to do some green marketing. To be genuine, you have to ensure that none of your business practices contradict your decision not to use plastic bags. What if customers who happen to walk behind your store see an overflowing trash bin filled with paper, cardboard and plastic bottles? Obviously, he or she will decide that you don't care as much about recycling as you say you do in your green marketing. Not using plastic bags appears to be environmental no-brainer, but you will still need to educate your target market. Did you know that a single use plastic bag takes about one thousand years to decompose? I didn’t until I researched this article and probably a fair number of otherwise environmentally conscious people don't either. This one little factoid about plastic bags could be used as part of your green marketing campaign - all by itself it lets the public know why single use plastic bags are environmentally disastrous and that you and your business care about the environment. And the third element? By shopping at your store, the customer is taking action to protect the environment by preventing at least one single use plastic bag from......

Air Bags

...is to someone, one would simply say it is a bag that inflates during a car crash to save someone's life. But to dig deeper, what is the science behind an airbag and does it always work? An airbag is a nylon bag in the steering wheel of a vehicle. When the censor in the steering wheel goes off that an accident has happened, the airbag inflates within two milliseconds. Within the nylon bag, there is a mixture of sodium azide (NaN3), and potassium nitrate (KNO3), that react when the airbag sensor goes off (Brian). This reaction causes an explosion, “[filling] the airbag with about 67 liters of nitrogen gas- which is enough to inflate a normal air bag” (Scientific America). Theoretically, in the right amount, this will inflate the airbag to the right amount to save the person's life. However, this is just theoretically. In some instances, the airbag may inflate too much or too little, and fail to save a life. Although the scientists that design the airbags use ut-most caution, not every experiment will turn out the same and inflate the airbag perfectly. In an experiment conducted here at "Charley's Newspapers" we stimulated the reaction between baking soda and vinegar by blowing up a plastic bag that was designed to save an egg. This was to get a feel on how accurate an airbag may be. Using very precise stoichiometry, our scientists here had found that .8 grams of baking soda and 11 mL of vinegar should theoretically blow the plastic bag up enough to save the egg's life.......

Bag the Ban or Ban the Bag

...Ban the Bag or Bag the Ban: An In-depth Look Into Austin’s Ban on Single-Use Bags In today’s day and age, the topic of environmental sustainability and the protection of the environment are found at the basis of a multitude of political debates and arguments. The way we, and our government, view the protection of the environment and the impact we have on the world around us has shaped the types of policies that governments in the U.S. have passed. One of these policies which has been implemented in a variety of cities around the United States, including Austin, is the ban on single-use plastic and paper bags. This ban has been hotly debated, and there are many people who view it as beneficial and many others who see it as unnecessary and imposing. Either way the impacts of this policy are far-reaching in how it can affect customers, businesses, and the environment. In this paper, I will show the conflicting arguments in this ongoing debate, focusing on the bag ban implemented in Austin in early 2013. We will begin by looking at the two opposing sides to the argument. There are many groups of people who advocated for the implementation of a city ordinance banning single-use bags in Austin and who continue to support it. The Austin City Government, led by Mayor Lee Leffinwell, and the Austin Resource Recovery, formerly known as the Solid Waste Services (SWS) Department, were the main proponents who pushed the ordinance into effect. In addition, the Zero Waste Advisory......

...UNIVERSITY OF MALAYA CRITICAL THINKING CBEB1108 PLASTIC BAG SHOULD BE BANNED WHAT IS PLASTIC BAG? Plastic bag is used to carry item especially from store to home. Most of the time plastic bag is used for storage and trash in common. Plastics are made from non-renewable natural resources such as crude oil, gas and coal. IMPACT The impact of plastic bags on the environment is enormous. As of August 2010, between 500 billion and 1 trillion plastic bags are being used each year worldwide. Approximately 100,000 sea turtles and other marine animals die every year because they either mistake the bags for food or get strangled in them, says Natural Environment. In Australia, 50 million garbage bags end up as litter yearly, and the "plastic soup" patch floating in the Pacific Ocean is twice the size of the continental United States. It is roughly 80 percent plastic, according to The Independent, a British newspaper. What exactly the impact of reusable bag usage in the U.S. is far from clear. Even though, according to the website Earth 911, reusing or recycling one ton of plastic means the equivalent of 11 barrels of oil are saved. ALTERNATIVE As we can see nowadays grocery chain carries cheap reusable grocery bags and more upscale bags are available in practically all chain stores. In addition, many people sew their own from leftover fabric or by converting old jeans or beach towels into personalized carry-on bags, which is fun and creative way to......

Why Not to Use Plastic Bags

...Why not to use Plastic bags As everyone knows the humble plastic bag has become an integral part of our lives. In fact the plastic bag has become so common that we hardly notice their presence. Yet if you look around you will notice that we are all in a swamp of plastic bags! They are everywhere. We use them to pack clothes, shoes, pens, tools, video games and even fruits and vegetables. At the super market they are soft yet strong packing medium. They are light weight, high strength and very flexible and come at a low cost. All of this might sound wonderful.

Did you know they are a slow poison in our daily life? When you use plastic bag do you know how they are made?

War on Plastic Bags

...War on Plastic Bags The battle between individuals who are committed to saving environment and those who seem not to be as interested has become a bigger battle. Our environment is changing whether we see it or not, the ecological footprint that humans are leaving is becoming greater. More impactful to the wildlife causing noticeable changes that is harming rather than helping. These impacts revolve around trying to sustain a lifestyle that as Americans we have grown accustom to. Around the late 50’s the first “Baggies” for sandwiches were introduced. Slowly after that the use of plastic as bags began to increase and increase. Consumers took a liking to the use of plastic bags and the production and use of them increased. This increase of usage of plastic bags has already created irreversible damage to our environment therefore plastic bags should be banned on a national level. Although there are some positives to using plastic bags, the negatives of using the bags out way the positives. Landfills are becoming filled with plastic bags waste, according to the Clean Air Council, “30,000 tons of waste is created from plastic bags each year”. Not only does plastic bags accumulate trash in landfills, they are seen more and more in the ocean and other water sources. “Plastic constitutes approximately 90% of all trash floating on the ocean’s surface, with 46,000 pieces of plastic per square mile”.

Plastic Bag

...Plastic Bag Jeff Blanchard COMM215 November 3, 2014 Gayle Thomas Plastic Bag I feel that the Senate Bill 270 has too many negative consequences to be of significant value to the citizens California. Because of the dramatic change in environmental resources used and the financial impact for fixed income citizens. The tax increase on California consumers are also an issue. This bill is a ban on the use of single use plastic bags at grocery stores. Which has been a controversial subject for a number of years. I think this is the worst decision that the Governor has ever made. On September 30, 2014. The California Governor signed a very controversial bill that bans the use of single use plastic bags in grocery stores in the State of California. “This bill, as of July 1, 2015, would prohibit stores that have a specified amount of sales in dollars or retail floor space from providing a single-use carryout bag to a customer, with specified exceptions.” (California SB270). First of all, I would like to state that there are two very opposing arguments that view this bill. To ban and not to ban. I would like to state my position as not to ban the use of plastic bags. This ban like some others will affect all the citizens of the State of California. In which, we will all either have to pay for the use of paper bags or buy reusable grocery ones. It requires all grocery stores to “charge a fee” for paper bags at no less than .10 cents a bag or, sell reusable bags. “Union......

...2015 LD 325 An Act to phase out the use of single use plastic shopping bags LD 325 An Act to phase out the use of single use plastic shopping bags One hundred and sixty thousand plastic bags are used globally every second of every day. China, a country of 1.3 billion, consumes three billion plastic bags daily, or one trillion ninety five billion per year, according to China Trade News. (Plastics News) In 1965, Celloplast came up with the design on which all modern plastic shopping bags are based: a tube of plastic sealed at the bottom to allow for the packaging of goods, an open top to insert such items into the bag and handles for convenient carrying. This bag is commonly known as the T-shirt bag or single use plastic shopping bag. By the end of 1985, 75% of U.S. grocery stores carried plastic bags in addition to paper ones, and today, plastic bags have secured more than 80% of the grocery and convenience store market. When Exxon Mobile introduced these bags to the U.S. in the late 1970’s they were immediately met with controversy. Not only were people worried about the environmental impact of the plastic, but suburban shoppers preferred paper bags that would stand upright in the trunks of their cars, while city folk liked the handles on the plastic bags to carry on their walk home. Plastic bags won the minds and hearts of business owners worried about their bottom line. (Petru) Plastic bags are much cheaper to purchase than paper by up to 4 times. The plastic is......

Plastic Bags: Cause for Concern

...Plastic Bags: Cause for Concern Todd Kuchelmeister May 30, 2012 As man continues to develop and his knowledge grows he will continue to be the dominate species on earth. His ability and desire for finding ways to make his life easier have produced many new and innovative things. From electricity to automobiles to fulfilling his dream of putting men on the moon, man has always strived to overcome those things which had earlier seemed impossible. However, with all new the developments that man has accomplished most have come with a downside for the environment. Electricity depending how you produce it has a downside, Nuclear energy comes with radioactive rods that take thousands of years to lose it radioactivity. Coal fired plants cause destruction of to the ecosystem and the emissions pollute the air. Solar and Wind are still in their infancy but their current issues seems mainly to be in the sheer numbers needed to produce enough electricity for an average sized city. One of mans greatest inventions was plastic, its invention back in 1855 called Parkesine has developed into mans most widely used products. Its invention has made man’s life not only easier but safer as well and is even used in the effort to keep people alive. However, as with all of man’s greatest inventions it has a dark side. Polyvinyl Chloride or PVC has phthalates that leech out of the PVC and into our bodies ("Life less plastic," 2007)....

Plastic Bags in America

...Plastic bags are distributed everywhere, from grocery to book stores. These bags have been used since the early 1850’s. One trillion plastic bags are produced each year, yet billions of these bags have ended up in landfills or on the streets and in the ocean. They are wasteful, destructive, and uneconomical. Plastic bags should be banned to protect ourselves and our environment. To begin, plastic bags are dangerous to children and wildlife. Every year, 25 children in America die due to suffocation from these bags. Likewise, many animals have died from plastic bags as well. Some bags float into the ocean and resemble jelly fish. Then, the bags enter the animal’s digestive system. In addition, the bags litter the streets and producing them pollutes the air. Many cities, including San Francisco and Seattle, have already banned plastic bags. However, plastic bags should be banned everywhere to help our children, animals, and environment. Furthermore, plastic bags waste numerous resources. They are made from a non-renewable source, petroleum. 12 million barrels of oil are used to produce these bags in the United States. In addition, fabric-made bags can be used numerous times, so factories do not have to produce as many. We are wasting many non-renewable sources by producing plastic bags instead of fabric bags. Banning plastic bags would save many of these sources for other products. Also, living without plastic bags would save numerous amounts of money. So why waste......
