In Ozymandias and Spring and Fall how do Shelley and Hopkins explore the passage of Time? Ozymandias and Spring and Fall are two poems, which at first glance have little in common. Ozymandias is a traveller's tale, a story that reminds the reader of something they have read before, perhaps in a children's book, long ago. This is shown in the first line - "I met a traveller from an antique land". It sounds like the beginning of a well-known story and the reader can tell instantly that it will be about the past by the use of the word "antique". The description of the place is a description of somewhere foreign, unfamiliar in everyday life as the word "desert" is used, yet in the reader's mind it was once a place of happiness, somewhere they could escape to as a child when they read books. However Shelley has taken it years later and it is now a dismal place - "boundless and bare" is used to show how little remains. He is appealing to the reader's imagination of what could have been by describing the fallen kingdom that is. He is looking back on time that has passed. In contrast, in Spring and Fall, Hopkins is talking of time that is currently passing, rather than looking back on time that has gone already. Unlike Shelley, Hopkins is talking to a certain person, rather than just any audience who happens to be reading the poem. Spring and Fall is a very personal account of the
Calculating the value of "g" (Gravitational field strength) using a mass on a spring
Calculating the value of "g" (Gravitational field strength) using a mass on a spring Gravity affects all things that have mass and therefore must affect how much a mass placed on a spring will extend. Measuring the time period and extension of a mass on a spring for vibrations should enable us to calculate a value for g. Using the following formula will help us to do this: Formula 1 T=2?Vm/k g (gravitational field strength) affects the spring constant - k in the formula F=ke and because F = weight = mg. Therefore mg = ke and m/k = e/g. We can now change formula 1 to the following: T=2?Ve/g If we rearrange the above formula so that the subject is T2 we should get the formula below: T2 = 4?2 e g Measuring T would allow us to calculate T2 (The time period - to calculate measure the time it takes for a certain number of oscillations and then divide it by the number of oscillations) and e would allow us to plot a graph and, according to the formula if we take the gradient of the line of best fit it will be equal to: 4?2 g We can then work out g, the gravitational field strength. g= 4?2 _ Gradient The graph that will be plotted will be T2 against e (time period2 against extension) and I expect that it will be similar to the following sketch: I predict that the gravitational field strength I calculate will be quite close to the 9.8N/Kg that is taken to be g
The aim of this investigation is to ascertain the effect of weight on a child's toy in relation to how high it will bounce.
Physics Sc1: 'Bug-up' Toy Investigation Aim The aim of this investigation is to ascertain the effect of weight on a child's toy in relation to how high it will bounce. Background After playing with the toy, I looked at how it worked. It is a very simple mechanism that is shown above, consisting of a plastic base with a coiled spring wrapped around the centre. On top is a red rubber 'sucker' that grips to the base when you press down. The spring slowly forces the two apart and it then flies up in the air. To find out the energy stored in a spring, you can just apply the equation for work done, replacing distance with compression. This way you get w.d. = Force x Compression. Then, to find out the energy stored in the spring, you need to know the area under the line when it is plotted on the graph, like in the example below: To find out the area, the equation is 1/2 x base x height. This makes the equation for the amount of energy stored in a spring 1/2 x force x compression. The force and the compression on the spring in this toy will always be the same, more or less. This energy stored in the spring will be equal to the toy's gravitational potential energy, as Einstein said that energy cannot be created or destroyed, just changed from one form into another. Providing no energy is lost, the transfer of energy from the spring will be 100% compared to the amount of energy
Investigation into factors affecting the time period for oscillations in a mass-spring system.
Investigation into factors affecting the time period for oscillations in a mass-spring system When a mass is attached to the end of a spring the downward force the mass applies on the spring will cause the spring to extend. We know from Hooke's law that the force exerted by the masses attached to the spring will be proportional to the amount the spring extends. F = kx When additional downward force is applied to the spring we can cause additional tension in the spring which, when released, causes the system to oscillate about a fixed equilibrium point. This is related to the law of conservation of energy. The stain energy in the spring is released as kinetic energy causing the mass to accelerate upwards. The acceleration due to gravity acting in the opposite direction is used as a restoring force which displaces the mass as far vertically as the initial amplitude applied to the system and the process continues. A formula that can be used to relate mass applied to a spring system and time period for oscillations of the system is T = 2?VM/k This tells us T2 is proportional to the mass To test this relationship an experiment will have to be performed where the time period for an oscillation of a spring system is related to the mass applied to the end of the spring. Variables that could affect T Mass applied to spring; Preliminary experiments should be performed to
Radio Waves
Radio Waves With wavelengths varying between 0.5 cm to 30,000 m, radio waves have the longest wavelengths in the electromagnetic spectrum and can channel innumerable forms of data through air, usually over millions of miles. Radio waves are not just transmitted from radio stations and onto one's boom box; but are also emitted by stars. Technologies such as communication, wireless networking , AM and FM broadcasting, GPS, radars, satellite communication and microwaves rely on radio waves to function. Radio waves are a long-wave pattern of radiation that transfers energy through the interaction of electricity and magnetism. In 1864, Scottish physicist James Clerk Maxwell developed the electromagnetic theory; a mathematical theory that established that magnetism and electricity were associated. In the 1888, German physicist Heinrich Hertz proved Maxwell's theory by discovering long- wavelength radio waves and confirmed it in his book, "Investigations on the Propagation of Electrical Energy". In his experiment, an induction coil producing high voltage was connected to a metal pedestal where a spark produced electromagnetic waves that reached the resonator. Here, an electric current was produced and formed a spark in the spark gap that helped Hertz detect the radio waves. Consequently, Hertz's discovery of the radio waves sparked new inventions and technologies.
To find out if the motion of an elastic band changes the tension, by the rate of its extension
Kirandeep Banga. Year 11 Physics Assessment. Aim The aim of the investigation is to find out if the motion of an elastic band changes the tension, by the rate of its extension. So in other words if an elastic band is extended to 20cm, will it move at a greater distance once its catapulted through the air, then a band which is say extended to 10cm, and if so why? Is the height achieved by the band, related to the amount of tension that exists within the band while its being extended, before it's catapulted? Method To answer the questions asked above, I plan to carry out an investigation, in which I will catapult an elastic band in to the air, which will be extended from various extensions, I will then proceed to measure the distance travelled by each new extension of the elastic band, using a meter rule, and from my result determine certain trends from the graph to answer the questions asked above and to conclude my predictions made for the overall experiment. The length at which the elastic band will be extended to, will start from an extension of 0.02m , and will continue all the way up to 0.08m. Two meter sticks will be cello taped to the wall so that when the elastic band is catapulted, the distance travelled by the band can be measured from the meter stick. The elastic band will be catapulted off the end of another meter stick, in front of
An Investigation into the Factors, which affect the Voltage Output of a Solar Cell
An Investigation into the Factors, which affect the Voltage Output of a Solar Cell My aim is to try and find out how much the voltage is affected when exposing different sized areas of a solar cell to a light source. From this I will also establish the energy of each photon and approximately, the number of freed electrons, which can make an electric current flow. I know that light consists of packets or quanta of energy called photons. When electromagnetic radiation such as light shines on materials (usually metals), which emit electrons the light photons containing energy are captured by the electrons. This means that the electron absorbs the energy from a photon thus allowing it to escape from the surface of its material. For each light photon landing on the surface of a material which emits electrons, an electron can be 'free'. I know that solar cells contain thin wafers of silicon protected by glass. When light photons strike the surface of the solar cell, energy from the photon is absorbed by an electron. The electron needs a certain minimum energy to escape the material but excess energy or surplus energy is transferred to the electron as kinetic energy. Thus creating an electric force, this pushes the electrons around a circuit, known as an electric current, when the solar cell is connected up. The size of the voltage depends on the number of flowing or 'freed'
Investigate the way in which extension depends on the tension for rubber.
Brendan Lee Tension and Extension Aim: To investigate the way in which extension depends on the tension for rubber. Before I begin to do this experiment I need to know a little more about elastics. I got my self an elastic band and placed it over my forefinger on each hand. I gradually increased the tension of which I was applying. The original length of the elastic band was 3 cm, but when stretched to its furthest length, it had a length of 21 cm. This meant that it had an extension of 18 cm. The band could not stretch any further than this. If I had exerted even more tension the band would have snapped. I also noticed that after being stretched a few times, and then compared to an exact sized band that had not been stretched, that it did not return to its original shape. It had increased in size by a small amount. However if I only stretched the band a little bit each time, it would return to its original size. When tension is applied to the elastic band, the band automatically begins to repel that force that is stretching it, and when released the band moves back to its original position. When the band is stretched something is pulling the band in the opposite direction, a force. Now the band is stretched it has the potential to do work. We know this as if we released the tension on it the elastic band would pull its self back to its original size and shape. The band
The aim of this experiment is to investigate whether the colour of light incident on a medium affects its refractive index.
Refractive Index Praveen Ravi G 11 Lab Report Aim - The aim of this experiment is to investigate whether the colour of light incident on a medium affects its refractive index. Background - Refraction is the bending of light when it passes from one medium to another. Refraction occurs because of the change in density in the new medium which changes the amount of obstruction of the light causing the light to deviate from its original path and take a new, shortest one through the new medium. Refractive index is a unique property of transparent and translucent materials. It is governed by Snell's law µ = Sin i / Sin r where i and r are the angles of incidence and refraction respectively and µ is the refractive index and is defined as "A property of a material that determines how fast light travels through it."1 Hypothesis - I believe that the refractive index of a transparent or translucent medium is independent of the colour of light incident on it. Light always travels in a straight line. When a ray of light enters a medium at a certain angle, it is forced to bend because of the change in density in the new medium and thus, a change in obstruction. The ray will have to deviate from its original path and find an alternate, short and straight way through the atoms of the new medium. Any colour of light will have to follow this same path for the shortest and straight way
Forces, waves and radiation.
Forces, Waves and Radiation Springs Aim To investigate which factors affect the length to which a coiled spring stretches when a force is placed upon it, and whether the size of the coils makes any difference to the results. Prediction I predict that the heavier the weight placed one spring is, the more it will stretch as the greater the mass, the greater the force of gravity is, pulling the spring. I also think that the bigger the coils are, the less amount of weight the spring needs to stretch to its elastic limit. Apparatus * Wire (plastic coated) * Retort stand * 30cm ruler * Pen (to coil wire) * Slotted mass hanger Method To perform this experiment, I am going to take a length of plastic coated wire and wrap it around a pen, which will make the wire into a circular spring. I shall then be suspending the spring from a clamp and stand. I shall then place my weights on the lower end of the spring. I shall start the experiment by measuring how long the spring is at the starting point which enables me to take the other results accurately. After that task has been completed I shall be suspending a 50g weight from the spring. This will hopefully stretch the spring slightly. I will then measure the length of the spring and take away the starting point measurement, which will then give me an accurate reading of how far the spring has stretched. I shall then perform
