inter-atomic spacing (d) between the graphite atoms‚ which we are accelerating electrons through. As the electrons pass through the graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents a different interatomic spacing in the graphite lattice structure. As we increase the voltage of the potential difference in intervals of .5kV from 2.5kV to 4.5kV‚ the diameter of the interference pattern will decrease

The termites’ reaction to pheromones in different colors of ballpoint pen ink. Abstract: We conducted the experiment with termites in order to determine how they react to pheromones present in different colors of ballpoint pen ink. The experiment consisted of two parts: in first part we used a ballpoint pen with blue ink‚ in second – a ballpoint pen with red ink. The reaction of termites was measured by their performance in 1 minute. Every termite in experimental group went through 3 tries in each

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

Cultural Anthropology Case Study: Cahokia Mounds In southern Illinois in Collinsville‚ the largest prehistoric settlement north of Mexico can be found. This is the Cahokia Mounds State Historic Site which is 4‚000 acres. How Cahokia began and ended to this day is still considered a mystery. The people of Cahokia built more thank 120 earth mounds as landmarks‚ tombs‚ and ceremonial platforms. The largest of these mounds is Monks Mound. It covers more than 14 acres‚ and it once supported a 5‚000-square-foot

starting puberty; one breast grows larger than the other. In her conversation with herself she knows her innocence has vanished‚ and a development is changing her life once again; the baby growing within her. The circles remind me of life. There is a beginning and an ending. The circles in this painting are in locations of the body that develop at a much faster pace than the

Area of the Circle 1 1. Calculate the length of the radius. If you only know (or have measured) the diameter (the distance from one side of the circle to the other)‚ then divide it by two to obtain the radius. The radius of a normal circle is always one-half of the diameter. 2. Read the formula. The formula for finding the area of a circle is Area equals pi multiplied by (r squared) 3. Multiply the radius by itself to square it. For example‚ if your radius was 6 cm‚ your radius squared

what is pi? ‚ And what is the area of a circle? The obvious assumptions would be the numerical approximation 3.14 and the formula of the area of a circle‚ pi*r^2. However‚ as we soon learned Pi is the ratio of a circle’s circumference to its diameter or the number of radius squares needed to completely cover a circle exactly. And the area of a circle is the unit squares needed to cover a circle exactly‚ or the space inside the boundaries of a circle. Such revelations prompted the lessons that

are going in a circle. The second principal I think of is proximity as the circles are near to each other. The third principal I see is continuity .The rows of circles seem endless. 7. This image represents similarity which is one of Gestalt’s principals. The shadows create almost identical shapes on the wall. 8. This photograph represents more than one of Gestalt’s principles. The whole object can be described as figure and ground as it is obvious that the metal circle is the object
