The Rubik's cube has haunted peoples nightmares for decades. When it was first made, it was supposed to have “billions” of combinations though it actually has over 43 quintillion combinations (43,252,003,274,489,856,000 to be exact). Originally created to help students understand geometric concepts and 3D space the first wooden model was made in 1974 by Ernö Rubik and a couple of friends. After some time playing with it, Ernö realized he didn't know how to get it back to its original form. He reportedly
In this investigation I will be finding out how many labels are on an exposed side of a 3x3x3 cube when 27 small cubes are put together to make the large 3x3x3 cube. Method I will first start to count the number of small cubes out of the 27; have no labels, 1 label, 2 labels and 3 labels. Once I have done this I will the do the same for a 4x4x4 cube, 5x5x5 cube and finally a 6x6x6 cube and see if I can find a pattern. When I have found a pattern I will try to work out a formula and
aluminum and iron cubes to the nearest 0.5cm. 2. Use the balance to measure the mass of each item listed above to the nearest 0.1g. Part 2 Water Displacement 1. Obtain a 50.0mL graduate cylinder and determine its mass to the nearest 0.1g. Record in the appropriate space on your data sheet. 2. Fill the graduate cylinder to the 30.0mL mark with tap water. Remember to read the bottom of the meniscus. This is the initial volume, V initial. Place the aluminum cylinder and note the final volume, V final. Record
strength of concrete that is subjected to heat treatment with unheated one. Concrete ingredients available locally were obtained for the production of concrete cubes into a dimension of 15x15x15 cm. A total of 12 cubes were casted and then cured at room temperature (28 °C). The cubes were divided into 4 sets. Each set comprised of 3 cubes for each Water-Cement ratio. Two of these sets were cured for 14 and 28 days out of which one set each was heated at a temperature of 200oc for about 4 hours. They
peroxide and during the decomposition reaction when oxygen is produced, it would produce foam due to the detergent. Picture 1. The picture shows how catalase breaks down hydrogen peroxide into 2 products oxygen and water. https://www.youtube.com/watch?v=BbYsp1kXuzw The aim of the experiment was to investigate the effect of the increasing temperature on the activity of catalase in the dissociation of hydrogen peroxide. It was hypothesised that the highest rate of production of oxygen would be around
triangle is a right triangle, then the acute angles are complementary. Theorem 4-5 If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. Theorem 4-6 All right angles are congruent. Theorem 4-7 If two angles are congruent and supplementary, then each is a right angle. Theorem 4-8 Triangle Midsegment Theorem If a segment joins the midpoint of two sides of a triangle, then the segment is parallel to the third side and half its length. Theorem
Daily gum chewing common, but sales trend down Chewing gum makers have spent past five years publicly expressing their deep concern over steadily declining sales and negative trending consumer patterns in the U.S. and Europe. Sales are growing in emerging markets, mostly in Asia, because of the sheer expansion of these economies and their growing middle class. Global sales are expected to reach $22 billion in 2015 from $20 billion today. In Puerto Rico 19% of consumer ages 12 & up buy gum every
control speed. Energy consumption in a centrifugal fan and pump applications follow the affinity laws. Affinity laws determined that the flow is proportional to speed, pressure is proportional to the square of speed, and horsepower is proportional to the cube of speed. That means if an application only needs 80 percent flow, the fan or pump will run at 80 percent of rated speed and only requires 50 percent of rated power. In other words, reducing speed by 20 percent requires only 50 percent of the power

The unique nature of diamond is heavily dependent upon its composition, crystal structure, and mechanical, thermal, and electromagnetic properties.1 Of those dependencies, composition exacts the most influence over the characteristics. Crystal structure is the repeating pattern of diamond’s composition, and each of the properties are the result of molecular interaction which is determined by composition. Therefore, composition is paramount in the determination of the qualities of diamond. Before
We have had keyboard input since the very first personal computers. Customizable graphical user interfaces, or GUIs, have existed since the late 1970's, originating with the Xerox PARC [7]. GUIs have been the standard user interface since the early 1990's with various versions of Microsoft Windows and the Macintosh operating systems. The current evolution of the GUI is towards a three dimensional interface, such as that exhibited by Compiz
Instrument Details Name: Hydrometer Operation: A hydrometer is a measurement instrument used to measure the relative density of liquids, the ratio of a density of a liquid to the density of water. A hydrometer consists of a thin glass tube sealed at both ends and has a graduated scale. One end of the tube is usually weighted with mercury and bulb shaped, the mercury causes the instrument to float upright in a liquid. A hydrometer jar, a second glass tube is filled with the liquid being

known as the wavelength, denoted by the symbol λ (lambda), as shown in Figure 2. The frequency of a wave is defined as the number of waves passing through a given point per second. Figure 2 The velocity of a wave is given by the formula: v=fλ Where v = velocity (ms-1) f = frequency (Hertz) λ = wavelength (m) or if the wave is travelling through a vacuum: c=fλ where c = speed of light (ms-1) f = frequency (Hertz) λ = wavelength (m) Law of Reflection: When a ray of light is bounced or reflected
Rap Music Since the late 1980's rap music has been called the Anti Christ in our culture, because of it's so-called influence in people's life. People swear up and down that the music is why people, specially the youth resort to violent crimes. I think by saying this they are trying to cover up the real truth by giving simple answers. Rap is defined as a style of popular music consisting of

Che Guevara, a revolutionary in Cuba, has become an internationally recognized figure. While many people are familiar with his achievements of helping to overthrow and rebuild the Cuban government, his image has expanded well beyond his political success. Che’s picture has been seen all over the world, in every imaginable context. Many people associate Che Guevara with the very word “revolution,” while others remember Che as a brutal and ruthless guerilla. While everyone has their own interpretation

Chapter 1 INTRODUCTION The connecting rod or con rod connects the piston to the crank or crank shaft. Together with the crank, they form a simple mechanism that converts reciprocating motion into rotating motion. As a connecting rod is rigid, it may transmit either a push or a pull and so the rod may rotate the crank through both halves of a revolution, i.e. piston pushing and piston pulling. In modern automotive internal combustion engines, the connecting rods are most usually made of steel for
