Experiment 16: Kinetics: The Iodine Clock Jane Smith Purpose: The objective of this experiment was for students to apply their knowledge of kinetics and rate laws in order to determine the rate of a chemical reactions‚ activation energy‚ and frequency factors of those reactions. Specifically‚ this experiment was performed using a series of solutions with varying concentrations of KI‚ Na2S2O3‚ and (NH4)2S2O3 . Students recorded time elapsed to observe physical evidence of a reaction taking place

Symbolism Analysis: Gatsby’s Clock Have you ever wanted to turn back time and relive the past? In The Great Gatsby by F. Scott Fitzgerald‚ Fitzgerald tells a story of a man named Gatsby who was once poor and became wealthy in order to get Daisy‚ a girl who is a part of the “old money” society. He attempts to accomplish this goal by establishing a friendly relationship with Nick‚ who is Daisy’s cousin. Unfortunately‚ Gatsby’s goal of getting Daisy and reliving the past backfires and vanishes forever

Oscilations Pendula A pendulum consists of an arm of low mass with a bob‚ which has a higher mass‚ on the end. The top of the arm is pivoted so that the pendulum can swing. A pendulum will continue to swing back and forth indefinately‚ until it is stopped by air friction and friction within the pivot. When the angle‚ á‚ between the stationary line of the pendulum (the line towards which the movement tends) and the line of maximum amplitude of the pendulum is quite small‚ then the time period of

The Birth of the Swatch During the 1980s‚ Swatch experienced an outstanding success as a result of careful and well-executed marketing plan‚ while just a few years earlier there was observed a rapid decline of the Swiss watch industry. For many years Switzerland was world leader in the watch manufacturing industry. By 1945 they accounted 80% of the world total production. Starting from 1970‚ Japanese manufacturers actively began to produce and assemble quartz watches‚ which the Swiss mistakenly

Today I will be presenting my opinion on why I think teachers should not give homework to students. To start off‚ this is something everyone says. Us dedicated students wake up two hours earlier than there actual time of waking to get to school and study for seven hours. Isn’t that the obvious purpose of school? Education? Why are we given homework to do at home when learning could have taken place at school? Or maybe teachers know that they aren’t doing a good enough job! What shocks me is that

Watch essay I am going to compare 4 watches each by different designers. I will compare the watches‚ look at the materials‚ colours and special features‚ who would wear the watch‚ compare the shapes and find out the differences between classy and sport watches. The first watch that I have been looking at is a classy ladies watch. It is made by Lorus and is silver with a mother of pearl face. The watch would be worn by a sophisticated lady who is quite wealthy. She would probably be in her early

Research Question: How does the length of a paper clip pendulum affect its period of oscillation? BACKGROUND INFORMATION: The simple pendulum: A pendulum is an example of a vibration with a regular‚ consistent motion. A simple pendulum is one which can be considered to be a point mass suspended from a string or rod of negligible mass. It is a resonant system with single resonant frequency. For small amplitues‚ the period of such a pendulum can be approximated by: Where‚ L – length of pendulum‚

In The Death of Grandfather Clock‚ Lin Lane depicts the nagging effect that time tends to have by utilizing symbolism. In the first stanza‚ the poem expressly states‚ “I am quite annoyed by the ticking... By the ever-present clicking”. The poet explicates how the constant ticking stresses the limited time one has to fulfil one’s responsibilities and aspirations. In the second stanza‚ Lane expands on her point by wondering‚ “Must Grandfather Time command my life?” The poem uses the “Grandfather Time”
