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

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”

EFFECT OF CONCENTRATION ON REACTION RATE The aim of this experiment is to find the effect of varying the concentration of iodide ions on the rate of reaction between hydrogen peroxide and an acidified solution of potassium iodide: H2O2(aq) + 2H+(aq) + 2I⁻ → 2H2O(l) + I2(aq) The course of this reaction can be followed by carrying it out in the presence of small quantities of starch and sodium thiosulfate solutions. As the iodine molecules are produced they immediately react with the thiosulfate

This experiment was a Landolt Iodine clock reaction - Oxidation of Bisulphite by Iodate. It involved conducting three measured experiments. The first variable tested was concencentration. This was tested by conducting two experiments‚ each varying the concentration of either the NaHSO3 or KIO3. The varying of NaHSO3 involved using 0.1 Molar of KIO3 against decreasing concentrations of NaHSO3 (0.25 M‚ 0.125 M‚ 0.0625 M and 0.03125 M). When decreasing the concentration of KIO3‚ 0.25 M of NaHSO3 was

in the world interpret time in different ways. So‚ do we share time? We all live in the present‚ but do all cultures in the world view the past and the future as holding the same level of importance? In a globalised world it is easy to synchronize clocks‚ but is synchronizing cultures as easy? Around the world‚ some cultures don’t see time as something that should control their lives‚ some cultures believe that time is everything‚ whilst others have no concept of time whatsoever. We now live in a

The reality of death is viewed through James McAuley and W.H. Auden’s poems “Pieta” and “Stop all the Clocks”. Comparatively McAuley’s “Pieta” is an anniversary poem written one year on from the death of the narrator’s child whereas Auden’s “Stop all the Clocks” explores the emotional loss felt between an individual who cannot accept the death of a loved one. McAuley provides context in “Pieta” when readers realise the poem is an anniversary poem. It has been one year since the narrator’s child
