Batteries and Their Importance
We use batteries everyday, we use them to start our cars and
to listen to our Walkmans. I have a few questions: How do batteries
work? What are the different kinds of batteries? Why do they die? Why
do they lose energy when they are not used for a long time? Well I
tried my best to find the best answers for these questions and a
little more.
Battery, also called an electric cell, is a device that
converts chemical energy into electricity. All batteries contain an
electrolyte, a positive electrode, and a negative electrode. There are
two general types of batteries. Batteries in which chemicals cannot be
reconstituted into their original form once their energy have been
converted these are called primary cells. Batteries in which the
chemicals can be reconstituted by passing an electric current through
them in the opposite direction are known as secondary cells, are
rechargeable cells.
The primary battery is the most common type of battery used
today, invented by the French chemist Geoges Leclanche in the late
1860’s. At the time this invention was very important and helped the
start of the industrial revolution. It allowed people with portable
electricity. This popular invention was called the dry cell or
flashlight battery. The Lechlanche cell is very similar to the dry
cell we use today. The positive pole is a rode of carbon embedded in a
black manganese dioxide (MnO2) and Carbon particles and the negative
electrode is made of zinc. The electrolyte consists of a mixture of
ammonium chloride and zinc chloride made into a paste. This sits in
between the negative and positive electrodes, which acts as an ionic
conductor. When the cell is in use, atoms of the Zinc in the outer
case are oxidized, giving up electrons and forming zinc ions.
Zn - 2e ® Zn++
The electrons are lost by the zinc atoms then flow through the load
(the device being powered) and supply energy. They re-enter the cell
at the carbon rode that serves as the positive electrode. As this
series of events happen, the battery begins to lose pure zinc atoms,
and the battery starts to die. This type of cell gives abo...

...e 1900’s. It works
similar to the lead-acid battery, but it is much smaller. A
disadvantage is that the battery loses a little bit of capacity each
time it is charged.
In recent years a number of new types of batteries have been
designed for use in electric vehicles and other applications. In
improving various conventional storage batteries, they have been able
to make electric cars and longer lasting batteries. Still there exits
some draw backs to these batteries, either short range, high expense,
bulkiness, or environmental problems. The U.S Advanced Battery
Consortion (USADC) was set up in 1991 to speed up development of new
storage batteries. Batteries are being developed that cause no
environmental hazards and occupy little space. All this advancement in
batteries is wonderful, but we need to see the importance batteries
play in the world today. The world is dependent on the battery, from
the use in cars to calculators. The battery is one of the few sources
of energy that is universal, a Japanese calculator can still work with
batteries found in the U.S no electric conversion is needed. This is
reason why the battery is so needed and important to the world.
The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done. The floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is

Utilitarianism is a concept formatted in a book by John Stuart Mill that welcomes the idea of utility in everyday life, while focusing on how to achieve complete happiness in the lives of humans. Nature automatically guides the living creatures of this toward always pursuing pleasure and to avoid pain, and this reigns true in lives of humans as people strive for greatness and in animals as survival is a pleasure for them. It is clear that in life, some pleasures are not worth the action and some pains should be
...heir energy get stored in the soil and used again in the cycle. For example: the red oat grass is consumed by the Thomson gazelle, the Thomson gazelle is then attacked and consumed by the cheetah, the cheetah is consumed by the lion, the lion once dead is consumed by the vultures and the land scavengers, and they are consumed by the decomposers.
In chapters two and three of Mill’s Utilitarianism writings he chose to discuss Utilitarianism’s meaning and principles of Utility. As for the definitions of utilitarianism, Mill described it as, “The Greatest Happiness Principle” (Mill 10). Furthermore, utilitarianism seeks to promote the most happiness for the greater good (Mill 10). In accordance to that, actions are considered good actions if they promote happiness (Mill 10). As Mill describes the definition of Utilitarianism, he also discusses the definition of happiness. Mill describes happiness as, “Intended pleasure, and the absence of pain; by unhappiness, pain, and the privation of pleasure” (Mill 10). In other words, Mill believes that if someone is performing an action
Stem cells are unspecialized, meaning that they have the unique potential to become any other type of cell, such as a red blood cell or a brain cell. There are two types of stem cells: embryonic and somatic. Somatic stem cells are found in adults, and, as far as we know, are only capable of becoming specific types of cells (stem cells in the liver can only become liver cells, stem cells in bone marrow can only become red and white
In the first chapter, General Remarks, Mill points out that, even after 2000 years, this fundamental question remains controversial. In his opinion, neither the idea of a natural moral faculty nor the idea of intuitionism can help to solve the problem. Most of the people who have tried to solve it, however, have been influenced ‘tacitly’ by the greatest-happiness principle, the author argues.
Mill begins his essay on Utilitarianism by explaining his Greatest Happiness Principle, stating actions are right in that they promote happiness and actions are wrong if they take happiness away (Mill, “What Utilitarianism Is,” para 2). Following from this idea, happiness is pleasure, and unhappiness is pain and the privation of pleasure (Mill, “What Utilitarianism Is,” para 2). In defending the equivalence between happiness and pleasure from his critics, Mill makes the claim that there is “the superiority of mental over bodily pleasures chiefly in the greater permanency, safety, uncostliness, etc., of the former” (Mill, “What Utilitarianism Is,” para 4). He claims that pleasures can differ both in quality and qua...
In this paper I will present and critically assess the concept of the principle of utility as given by John Stuart Mill. In the essay “What Utilitarianism Is” #, Mill presents the theory of Utilitarianism, which he summarizes in his “utility” or “greatest happiness principle” # (Mill 89). Mill’s focus is based on an action’s resulting “happiness,” # pleasure and absences of pain, or “unhappiness,” # discomfort and the nonexistence of contentment, rather than the intentions involved (Mill 89). After evaluating Mill’s principle, I will then end this essay by discussing my personal opinion about the doctrine and how I believe it can be altered to better suit real-life situations.
One of his objections is that “Against this doctrine [of utilitarianism], however, arises another class of objectors, who say that happiness, in any form, cannot be the rational purpose of human life and action; because, in the first place, it is unattainable ”(266). He replies to this objective by explaining that happiness could be attained if society changed. Mill says that “The present wretched education, and wretched social arrangements, are the only real hindrance to its being attainable by almost all” (266). People are capable of being happy if they are taught the proper values.Another objection he discusses is that “ To suppose that life has (as they express it) no higher end than pleasure—no better and nobler object of desire and pursuit—they designate as utterly mean and grovelling; as a doctrine worthy only of swine, to whom the followers of Epicurus were, at a very early period, contemptuously likened”(263). Mill replies by saying that humans pleasure is of more value than the pleasures of an animal. He also explains that people have different quantities of pleasure. This basically means that some happiness is of higher value than other happiness. If a person would choose one pleasure over another it could be considered that it is of higher quality.In conclusion, John Stuart Mill defined utilitarianism as the maximization of pleasure itself and the reduction pain. The greatest happiness principle states that actions are good if the promote happiness amongst several people and they would be considered bad if they reverse this happiness. He also makes several arguments that support this
Gambling is described as the betting of money or property on the result of an event or game that is mainly random with the desire to win more money or gain additional property. The industry or sector created by the activity of legal gambling is referred to as gaming. Since inception, gambling and gaming has continued to develop to an extent that it worth more than $335 billion across the globe. Most of the revenues obtained in this industry are generated by casinos and lotteries. In the past few years, gambling and gaming have attracted significant concern and controversy, especially with regards to the morality of the practice and whether its financial benefits outweigh the damage. While proponents of gambling
The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
Stem cells are a type of cell unlike any other inside a human. They have unique properties as to what they are or can become. The U.S. Department of Human and Health Services states, “Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth” (stem cells). Because of this capability, they are the base of every single muscle and tissue in the human body. ”When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell,” or any other type of cell (stem cells). This special kind of cell has opened a new door of possibilities to all of
Stem cells research can help the human with cancer, birth defects and help to build normal cells it is only normal that we should research stem cells. Stem cells are special cells that are undifferentiated and have the capability to become many other types of cells. All stem cells have the ability to renew, replicate, and divide; thus, producing new cells. These cells are separated into categories according to their potential to become other types of cells. Two main stem cell types are embryonic stem cells and adult stem cells. Embryonic stem cells come from four to five day old embryos. They can be found on the inside of the placenta. These stem cells are considered pluripotent, meaning that they can become almost all possible types of
