Investigating the Resistance of a Wire at Various Lengths - Investigating the Resistance of a Wire at Various Lengths Aim To investigate the resistance of a wire at various lengths. Theory Current is the flow of electrons. Electrons will flow around a circuit so long as there are no gaps and there is a battery. When the electrons get to the battery they are charged up with energy, then they will go around to the component where they will lose this energy. The thickness and material of the wire determines how easy it is for the electrons to flow around the circuit....   [tags: Papers] 584 words

Investigating How Different Lengths of Wire Affect the Resistance in a Circuit - Investigating How Different Lengths of Wire Affect the Resistance in a Circuit Hypothesis: I predict that; the longer the wire, the more resistance there will be. So if the length of the wire were to double, so would the resistance. The reason for my prediction is: The flow of electrons is called a current, the electrons are constantly hitting atoms, which causes resistance. If the same amount of current is passed through a longer piece of wire, there will be more collisions, hence more resistance....   [tags: Papers] 944 words

Investigating the Relationship Between the Lengths, Perimeter and Area of a Right Angle Triangle - Investigating the Relationship Between the Lengths, Perimeter and Area of a Right Angle Triangle Coursework Aim To investigate the relationships between the lengths, perimeter and area of a right angle triangle. Pythagoras Theorem is a² + b² = c². 'a' being the shortest side, 'b' being the middle side and 'c' being the longest side of a right angled triangle. So the (smallest number)² + (middle number)² = (largest number)² The number 3, 4 and 5 satisfy this condition 3² + 4² = 5² because 3² = 3 x 3 = 9 4² = 4 x 4 = 16 5² = 5 x 5 = 25 and so 3² + 4² = 9 + 16 = 25 = 5² The numbers 5,12, 13 and 7,24,25 also work for this theorem 5² + 12² = 13² because 5² = 5 x 5 = 25 12² = 12 x 12 = 144 13²= 13 x 13 = 169 and so 5² + 12² = 25 + 144 = 169 = 13² 7² + 24² = 25² because 7² = 7 x 7 = 49 24² = 24 x 24 = 576 25² = 25 x 25 = 625 and so 7² + 24² = 49 + 576 = 625 = 25² I will now work out the perimeter and area Perimeter = a + b + c Area = ½ x a x b 3, 4, 5 Perimeter = 12 Area = 6 5, 12, 13 Perimeter = 30 Area = 30 7, 24, 25 Perimeter = 56 Area = 84 I will now put these three terms in a table Term Number 'n' Length of shortest side 'a' Difference between 'a' Length of middle side 'b' Length of longest side 'c' Difference between 'b' and 'c' Perimeter Area 1 3 2 4 5 1 12 6 2 5 2 12 13 1 30 30 3 7 2 24 25 1 56 84 As you can see from the table above the difference between 'a' for each term is 2 and the difference between 'b' and 'c' is 1 and if you times 'n' by 'a' and plus 'n' you get 'b' so 'c' is that plus 1....   [tags: Papers] 2080 words

Phonological Similarity of Word Lengths - Word length effect is the finding that the longer the words are that people need to remember, the fewer they can remember (Baddeley, Thompaon & Buchanan, 1975). In our research findings, there are three hypotheses; including letters that sound similar will be remembered worse than words sound dissimilar. Long words are remembered worse than short words. With long words presumably being more subject to error than are short words. Longer words are assumed to take more time to articulate, hence allowing a greater degree of forgetting, either from trace decay or from interference (Baddeley, 2001)....   [tags: long words] 577 words

A Comparison of Magazines and Newspapers - A Comparison of Magazines and Newspapers Introduction Suresh’s hypothesis seemed to me at first to sound quite correct, that words in magazines would be shorter than those in newspapers. But then I realised that this was taking for granted that the newspaper would in a way be more ‘serious’ than a magazine, as my first thoughts on a magazine were those that wrote about celebrities and contained a lot of photographs. However, I do not think that this generalisation would hold with all magazines and newspapers, for instance, if I was to compare a magazine such as “Sight and Sound” which is a magazine about films, but one that examines films in quite an in-depth way, having interviews and articles on ‘art-house’ films for instance – with a newspaper like “The Daily Sport”, aimed at men who prefer titillation to topical news stories, then I believed that Suresh’s hypothesis may be proved wrong....   [tags: Papers] 2771 words

Structure of a Wire - Structure of a Wire A wire is made up of positive ions and negative electrons. When the voltage is on, the electrons try to push in between the ions. The ions DO NOT MOVE. They are lined up. The electrons carry the current, which is measured in Amps. The voltage charges up the electrons, which is the then, the driving force of the electrons. When the voltage is on, resistance is caused between moving electrons and ions; energy is lost during these collisions.

Analysis of What Are Years? by Marianne Moore - In the poem “What Are Years,” written by Marianne Moore there are two poetic devices being used in order to convey the meaning of the poem. Through the use of different figures of speech and unique forms, she discusses the different life stages a person experiences. The entire poem is based on powerful metaphors used to discuss the emotions and feelings through each of the stages. For example, she states “The very bird/grown taller as he sings, steels/ his form straight up. Though he is captive (20-22).” These lines demonstrate the stage of adulthood and the daily challenges that a person is faced with....   [tags: Poems, Poetry Analysis] 261 words

The Concept of Love in Ovid's Metamorphoses - The Concept of Love in Ovid's Metamorphoses In Ovid's Metamorphoses, the concept of love seems to vary from character to character. In one case, a god in the form of a man desperately seeks a particular woman and refuses to relent until he has her. In another instance, a female goddess cares deeply for a man and goes to great lengths to protect him from danger. In yet another case, both who are arranged to be married seem indifferent about the matter.

The Storm - “The Storm” may be interpreted as a condemnation of societal constraints upon feminine sexuality. As Calixta “unfastened her white sacque at the throat” she was taking off chains of oppression of her sexuality. When Calixta “nervously began to gather up from the floor the lengths of a cotton sheet which she had been sewing” she is putting her duties away for pleasure and is finally going to fulfill her birthright for passionate sex. In “The Storm” Calixta is a shameless married woman who “lifted her pretty chin in the air and laughed aloud” after committing an adulteress act....   [tags: essays research papers] 394 words

Osmosis Experiment - Osmosis Experiment Planning Introduction Osmosis is the passage of water molecules from a weaker solution into a stronger solution, through a partially permeable membrane. In this case, the tiny holes in the membrane of the potatoes will allow the water molecules to pass through in and out of the solution and the potato, depending on the concentration gradient of the two substances. So in this case, when the water concentration is lower in the tissue, the water will go inside the tissue of the potato, and the potato will grow in length, and if there is very little difference in the two water concentrations, there shouldn't be such a big change in length....   [tags: Papers] 1643 words
