It was similar towards the experimental demonstrations because nothing changed or destroyed in the processes .Kinetic and potential energy was used in the experiments. Paragraph 2 - How the Law of Conservation of Energy is supported by the experimental demonstrations: Experiments do not consome the energy but conserve by changing them from one form to the other .This allows all energy to remain constant so for each experiment diffrent form occured but never changed the element of the experiment Fourth Scenario Describe a fourth scenario in which either the â€Å"Law of Conservation of Matter† or the â€Å"Law of Conservation of Energy† could be observed. Using as many sentences as needed, describe how an experiment could be set up to further explore your recorded observation. The goal is to show understanding of the concepts in the lesson. I choose law of Conservation of Energy Suppose a Hard mini ball is placed in an automatic air power sealed containerYou will notice that no matter how much you will leave the ball bunching the ball will never stop bouncing. That happens because the ball develops both potential and kinetic energy,the sum of those two give us the mechanical energy which remains constant.

Charlotte is having an early 20s existential â€Å"what do I do with my life† crisis whereas Bob who is much older than charlotte, is having a midlife crisis.

The title can also be interpreted as not being able to communicate with others regardless of the language barrier. The story centrally revolves around three characters; Bob and Charlotte who are our more conventional characters who are presented as equals in the story and follow similar journeys of discovery, their own internal conflicts. Bob arrives as a movie star in the twilight of his career in Tokyo to appear on talk shows and to film a whisky commercial, Charlotte on the other hand has come with her husband on business trip and lacks a real sense of purpose of her own. Both feel Isolated and have complicated and somewhat troubled relationships.

A scar can help you find beauty deep down inside just like Alice Walker did. Scars cannot tear you down you are the only one can, its either you live a lie or just accept the true you, which one would you choose? Walker also had problems with self-esteem in her life when her brother shot her in the eye with a BB-gun that left one of her eyes blind. According to walker her life was over â€Å"For six years I do not stare at anyone, because I do not raise my head†. I grew up a tomboy who played with nothing but boys and maybe one or two girls. I was always happy, and a just a big jokers until I started my middle school year and identified hair on my chin. We will write a custom essay sample on Dancing with self beauty alice walker or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I have suffered with this problem for the longest. I considered myself as different from most girls. When I got the hair on my chin I did not want to be bothered with anybody, I used to hold my head down and kind of slouch so no one wouldn’t see it. My whole attitude changed I went from the girl who used to love herself so very much into the girl who couldn’t stand to look in the mirror. But that should’ve have changed me nor Walker because you can’t look down on yourself just because you have a scar you are who you are no matter if it’s there or not. The scar also changed the relationship with her siblings. From the article Everyday life by K. Nola Mokeyane she said â€Å"sibling’s relationships are important component of children’s social and emotional development. The Child Welfare Information Gateway notes that through their relationship with their siblings, children learn skills such as conflict resolution and negotiation; healthy relationships also provide siblings with a support network. As with anything in life, siblings relationships have positive and negative aspects. Walker started to develop to like on sibling more than the other brother. One of the siblings brought both positive and negative change in her life. The brother who shot her with the BB gun when she was younger and made a big difference in her life and she just was less closer to him just like any other siblings in life. â€Å"What the matter with your eye? † they ask, critically. When I don’t answer with (I cannot decide whether it was an â€Å"accident† or not), they shove me, insist on a fight. My brother, the one who created the story about the wire, comes to my rescue. But then brags so much about â€Å"protecting† me, I become sick. It seems like she is still never forgave her brother for what he had done to her eye and began to not really like him as much. Since her brother was kind of a part of the accident so she kind of liked him better. For some reason he understood her more. â€Å"He is my favorite brother and there is a strong bond between us. Understanding my feelings of shame and ugliness he and his wife take me to a local hospital, where the â€Å"glob† is removed by a doctor named 0. Henry. There is still a small bluish crater where the scar tissue was, but the ugly white stuff is gone. † I to can relate to her by this I had a problem with the hair under my chin still to this very day and my mother wanted to help me out by getting lazer hair remover but I insist on doing so because it really wouldn’t make a difference if I got it removed or not, sometime down the line it still was going to be there no matter what I did. It is so much that family members are siblings can do for you, but you are the one who really have to decide what you are going to do with yourself. People don’t make you and how they change you, you do. According to Answers in Writing â€Å"Sometime we imagine ourselves as different than what we really are one way at least we picture ourselves as this, yet in reality we do not fit this picture. We think we are kind gentle, when in truth we have very little patience for things. We may see ourselves, it is good to see ourselves as exemplary students, but we hate to be wrong. However we picture ourselves, it is good to see ourselves for who we really are. Perception can be altered, whether it is how we see the world or how we see ourselves. All it take is a little honesty, without trying to make ourselves feel better, which is what we usually do when we see what we call faults in ourselves. We try to feel better about it, and this often means we find ways to alter behavior. We try to change how we are to supplement our perceived faults. We are far better off just seeing ourselves for who we are, leaving it at that. Walker use to be the prettiest girl that knew she was pretty and now she is kind of confused. She is worried about what other people think which is stopping her from seeing the positive in her life. â€Å"Years later, in the throes of mid-life crisis, I ask my mother and sister whether I changed after the â€Å"accident†. No, they say, puzzled. What do you mean? † What do I mean? Walker was question herself about who she really was are did she change and she wanted to see what other people such as her family and how they viewed her too. But it was all in the mind of how she saw herself. â€Å"That night, as I do every night, I abuse my eye. I rant and rave at it, in front of the mirror. I plead with it to clear up before morning. I tell it I hate and despise it. I do not pray for sight. I pray for vision. † She must have really seen herself as this person who so ugly until she got it removed but that didn’t change her she had to see herself from within. Many times I put myself in situation where I just look in the mirror and wish some things would go anyway but it doesn’t, you can put make up on, put hair on your head but it want change anything. Walker finally sees herself as this beautiful person. She keep questioning herself â€Å"You did not change they say. † But she finally realizing everything when she is by her daughter and she is talking to her daughter. Walker says â€Å"Since the birth of her daughter she has worried about her discovery that her mothers’ eyes are different from others people’s. Will she be embarrassed? I think. What will she say? Every day she watches a television program called Big Blue Marble. It begin with a picture of earth as it appears from moon. When walker was putting her baby to sleep her daughter Rebecca focus on her eye. She began wanted to protect herself but her daughter didn’t see her eye as such ugliness her daughter tells her there is a world in her eyes. From the perception of her daughter she began to accept herself. â€Å"Yes indeed , I realized, looking into the mirror. There was a world in my eyes. And I saw it was possible to love it. In conclusion scar is something that can be covered but never erased. Scars can change a person’s self-esteem and self- worth, relationship with people, and your perception of yourself. It would not make you who you are you can only make you who you are. Theirs is nothing no one can do to change it. You can never change something and in my eyes she never changed. She still look back and think about her eye.

Strict Constructionism vs Broad Constructionism free essay sample

Had developed into two distinct political parties. The controversy over the constitutionality of the First Bank of the United States gave rise to two different interpretations of the Constitution. While the Jeffersonian Republicans held a strict-constructionist view of the Constitution, the Federalists took on a broad-constructionist view of the Constitution. These became defining characteristics of the two political parties.However, during the presidencies of Jefferson and Madison, the desire of one party to nominate over the other caused both parties to stray away from their original philosophies of government and resort to the other partys principles. Although the Republicans and Federalists largely stayed true to their respective interpretations of the Constitution, they increasingly embraced the other partys principles to achieve their goals between 1801 to 1817. In establish inning Republican dominance in government, Jefferson determined to use strict constructionist; yet, with regard to westward expansion, Jefferson resorted to broad constructionist.Upon his inauguration in 1801, President Thomas Jefferson promulgated his belief in a limited government. We will write a custom essay sample on Strict Constructionism vs Broad Constructionism or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Congress, under Jefferson, restricted federal government by repealing all international taxes. In doing so, Jefferson reduced government spending, thus successfully limiting the power of the federal government. Similarly, the Secretary of the Treasury Albert Gallatin limited the military by cutting army and navy budgets significantly. These acts of frugality demonstrated the use of strict constructionist to assert Republican dominance.Jefferson interest n expanding westward prompted him to purchase the Louisiana Territory on the basis that he was protecting the nation. Jefferson believed that the results of this broad constructionist view would benefit America by encouraging economic development. Thus, Jefferson embraced both Republican and Federalists principles during his presidency. Seeing that Congress was dominated by Republicans, Chief Justice John Marshall appropriately adopted both strict and broad constructionist in his court decisions. In the Mammary v.Madison case, Marshall ironically gained a Federalist victory by using strict constructionist. By ruling that the Constitution did not explicitly grant the Court power to issue writs of mandamus, Marshall gave the Court the greater power of judging the constitutionality of laws passed by Congress through the judicial review. In this way, Marshall expanded the federal government, producing a broad- constructionist victory. In the Fletcher v. Peck case, Marshall did not need to use strict constructionist to accomplish his goal of advancing the power of the federal government.Instead, Marshall solely relied on broad constructionist to protect commercial and industrial interests and state federal supremacy in interstate commerce. In his court rulings, Marshall affirmed Federalist dominance in the Supreme Court amidst a Congress dominated by Republicans. By using both Republican and Federalist principles, Marshall elevated the Supreme Court and expanded the power of the federal government. The War of 181 2 prompted President James Madison to turn to Federalist principles of broad constructionist to structure Americas economy.Madison agonized the expediency of encouraging commerce and economic development as American nationalism emerged after the War of 1812. He concluded that state banks were insufficient in facilitating the economy and believed that a national bank could satisfy the needs of the country. Driven by a Federalist desire to stimulate economic growth, Madison allowed the charter of the Second Bank and the creation of protective tariffs. Republicans no longer deemed the national bank as unconstitutional because they recognized the importance of a bank that operated nationally. Madison also oversaw the implementation of the American System, which contributed greatly to economic development by encouraging the domestic economy. The use of broad constructionist to create an economic program allowed Madison to successfully stimulate economic growth. Though both Republicans and Federalists largely held on to their own philosophies of government, they strategically used the other partys principles to achieve their goals during the presidencies of Thomas Jefferson and James Madison.Jefferson found it necessary to use broad instructions in his decision to purchase the Louisiana Territory, but stuck to strict constructionist in shaping the federal government. Marshall successfully asserted Federalist dominance in the Supreme Court and protected commerce by using strict constructionist and broad constructionist, respectively. Madison effectively stimulated the American economy through Federalist principles. Between 1801 and 181 7, Republicans and Federalists increasi ngly made their decisions by adopting each others principles rather than sticking to their own interpretations of government.
