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

Mathematical Investigation - Mathematical Investigation Pythagoras was a great mathematician who created theorems and one of his famous theorems was the "Pythagoras Theorem". You start with a right-angled triangle. The hypotenuse is labeled "c". The bottom of the triangle is "b" and the side of the triangle is labeled "a". [IMAGE] Pythagoras Theorem says that in any right angled triangle, the lengths of the hypotenuse and the other two sides are related by a simple formula. So, if you know the lengths of any two sides of a right angled triangle, you can use Pythagoras Theorem to find the length of the third side: Algebraically: a2 + b2 = c2 The numbers 3, 4 and 5 satisfy the condition 9 + 16 = 25 Because 3x3=9 4x4=16 5x5=25 And so 9 + 16 = 25 [IMAGE] I now have to find out if the following sets of numbers satisfy a similar condition of: (Shortest Side) 2 + (middle Side) 2 = (Longest side) 2 [IMAGE] a) 5, 12, 13 a2 + b2 = c2 52 + 122 = 132 25 + 144 = 169 169 = 169 b) (7, 24, 25) a2 + b2 = c2 72 + 242 = 252 49 + 576 = 625 625 = 625 [IMAGE] (3, 4, 5), (5, 12, 13) and (7, 24, 25) are called Pythagorean triples because they satisfy the condition, (Shortest side)2 + (Middle side)2 = (Longest Side)2 We know from the Pythagorean triples the shortest side is always an odd number....   [tags: Papers] 3909 words

The relationship between the length and the period of motion of a pendulum - ... Newton’s second law, F=Ma=(d^2 (Lθ))/(dt^2 ) , shows that the arc which the pendulum swings through is actually a segment of a circle – with the radius being the length of the pendulum. The combination of these formulae demonstrates that the mass of a pendulum is independent to its period of motion (Encyclopedia Britannica, 2011). I concluded from this that a specific weight for my pendulum is not necessary, although it must remain constant. As seen in the above equation, this restoring force is not proportional to the angle θ but to sin θ, which means the resulting motion of the pendulum is not simple harmonic....   [tags: History, Galileo] 1085 words

As Kaplan elucidates on the principles of both Sun-Tzu and Thucydides, it is evident that they both believe that war is not an aberration.
