Investigating the Size of Craters in Sand when a Marble is Dropped into the Sand from Different Heights * Metal container * Sand * Marble * 1 metre rulers * 30cm ruler Method * First of all I collected all the equipment I needed. * Next I put the tub of sand next to the wall and leaned the ruler up against the wall resting on the sand. * I then took the marble and dropped it into the sand from different heights. * After each drop I took my 15cm ruler, measured
Roping is a sport that most believe simply to be timing and performance of the cowboy and the cattle. However, roping is actually much, much, more. One quality that is necessary for a roper to be successful is momentum. Momentum is the quantity of motion of a moving body, measured of a product of its mass and its velocity (Jones). This concept of momentum can determine what results are obtained by the roper. For example, when a cowboy rides a horse and the horse accelerates, the mass of cowboy
Computer Viruses: Infection Vectors, and Feasibility of Complete Protection A computer virus is a program which, after being loaded into a computer's memory, copies itself with the purpose of spreading to other computers. Most people, from the corporate level power programmer down to the computer hobbyist, have had either personal experience with a virus or know someone who has. And the rate of infection is rising monthly. This has caused a wide spread interest in viruses and what can be done to
strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA. Scientists started to build vectors, which incorporated genes of their choosing and used vectors to insert these genes into the DNA of living organisms. Genetic engineers believe that they can improve the foods we eat by doing this. At first glance,
The tsetse fly is predominant found in large areas of sub-Saharan Africa where there is human settlement and agriculture. The tsetse flies are cousins of the house fly, however they are larger than a common house fly. Approximate length of a house fly is 6 to 7 mm while a tsetse fly ranges anywhere from 6 to 16 mm in length. There are approximately 22 different kinds or species of tsetse fly living on the continent of Africa presently. The scientific name for the tsetse fly is Glossina. Each of the
I. Introduction A vector is an arrow whose length represents the magnitude of a quantity and whose direction represents the direction of the quantity. Vectors are useful in combining velocities that are not parallel. The sum of two or more component vectors is called a resultant. When the vectors are not at right angles to each other, the resultant is found by constructing a parallelogram. The parallelogram is constructed with the two vectors as sides. The resultant of the parallelogram is its diagonal
B. Wet and Wrinkled Finger Dataset To test the working of algorithm wet as well as wrinkled (WWF) dataset is used. In Wet and Wrinkled Finger (WWF) database . Data from 30 people for all ten fingers using a multispectral fingerprint scanner from Lumidigm (Venus series) was collected. 300 fingers were treated as separate identities. Multispectral sensors were specially used as they were effective for application . They were designed to function when the fingers are wet with dripping water, and they
example on an elevated ramp? But this can't be done because the theory states that free falling objects fall at a constant acceleration of 9.8m/s/s ONLY if gravity is the only force acting on it. To prove this, I will undergo an experiment involving vectors and mechanics. Apparatus: · Toy car · [IMAGE] Ramp with the length of 1m
they were not thinking, and the order began to tear the school apart. The teacher sought order because he wanted his students to behave better. Scientists use order to control viruses. Viruses are classified by several attributes; their shape, the vectors that transmit them, and their RNA or DNA content. Once a virus is classified, it can be examined, and controlled. Biologists use order to classify other organisms as well. Charles Darwin sought order instinctively by becoming a naturalist. He studied
GTR for spacetime ontology and, generally, ontology of nature. The preliminary remark, however, has epistemological character. The formulation of the GTR resulted in definite fall of a dogmatic thesis of distinguished value of the 3-dimensional Euclidean geometry, as the only geometrical structure, adequate for a description of nature. This thesis was formulated explicitly by Kant, who considered this structure to be apriori form of inspection, and as such it was to validate the science. Kant's epistemology
Linear algebra is used in the organization and sorting of these web pages when storing them in an internet search database. The vector space model;is used to enhance search results by representing them as two vectors, the document vector and query vector. Each dimension in the vector corresponds to a different term. If the term occurs in the document, its value in the vector is a non-zero value. Several different ways of computing the term weights have been developed, one of which is the frequency-inverse
study of catoptrics, conics, geometrical distances and vectors. Especially, his thirteen books of the treatise ‘Elements (Stoicheia)’ has defined the most area of geometry and later divided the geometry as Euclidean and non-Euclidean. The book of Elements discusses plane geometry (books I-IV and VI), number theory (V and VII-X), and solid geometry (XI-XIII). Amongst all thirteen books of the treatise, the most well-known topics are the Euclidean algorithm and the five axioms, or postulates. Regarding
Bit map vector graphics When using a graphics package the graphics file can have the image represented as a: 1.Bit map 2.Vector image A bit map files makes every dot or pixel on the screen has a single bit of information in a file. If it is in colour, you then need to store additional bits. The disadvantage to this is that if you want to alter anything you have to change it at a pixel at a time. When you enlarge an image, the number of pixels stays the same. In vector graphics, the
"Shape is that which alone of existing things always follows color." "A shape is that which limits a solid; in a word, a shape is the limit of a solid." In the play Meno, written by Plato, there is a point in which Meno asks that Socrates give a definition of shape. In the end of it, Socrates is forced to give two separate definitions, for Meno considers the first to be foolish. As the two definitions are read and compared, one is forced to wonder which, if either of the two, is true, and if neither
Pitch, Roll and Yaw Pitch, Roll, and Yaw have analogy of imaginary lines (three in number) that run through a typical aircraft and intersect at right angles at the aircraft’s center of gravity. Pitch- Rotation around the side-to-side axis. Roll -Rotation around the front-to-back axis. Yaw-Rotation around the vertical axis. Maintaining Control FIGURE 1 Maintaining Controls Rudder controls yaw The rudder swivels side to side on the vertical tail fin, hence pushing the tail in right or left direction
Euclid was one of the world’s most famous and influential Mathematicians in history. He was born about 365 BC in Alexandria, Egypt, and died about 300 BC. His full name is not known but Euclid means “good glory”. Little was ever written about Euclid and much of the information known are from authors who wrote about his books. He studied in Plato’s ancient school in Athens and later went to Alexandria in Egypt, where he discovered a well-known division of math, known as Geometry. Thus, he was named
While the study of curvature is an ancient one, the geometry of curved surfaces is a topic that has been slowly developed over centuries. The Ancient Greeks certainly considered the curvature of a circle and a line distinct, noting that lines do not bend, while circles do. Aristotle expanded on this concept explaining that there were three kinds of loci: straight, circular, and mixed (Coolidge)Then in the third century B.C. Apollonius of Perga found that at each point of a conic section there is
From wind-swept seeds to efficient flight mechanism, all animals and plants have evolved a variety of dispersal abilities and have an important role in understanding species survival and evolution. Dispersal is largely driven by needs for resource acquisition particularly to seek suitable breeding habitats. Individuals dispersing between populations aid in gene spread and as such dispersal is subject to natural selection. Three main evolutionary drivers are thought to result in dispersal - habitat
Basketball is one of America’s favorite pastimes. While a great defense wins championships, watching players on offense is arguably the most exciting part of the game. Transition offense, either a quick inbound and go or getting a rebound or turnover and swiftly moving up the court, is an important part of the game for teams to try to take advantage and score. In order to be successful offensively as a guard, players must be able to be somewhat quick, agile, and have court vision; power forwards
Kelvin Silvester R. Calomarde LBYPH11 EB2 Individual Lab Report Title: Graphs and Equations Introduction: The study of physics involve a lot of data to be studied that is attained from experiments. To interpret these data would be important in order to predict a certain phenomenon and explain why and how things work. A model for the data to be interpreted is with the use of graphs and equations. Stewart (2012), states that a graph of an equation in x and y is the set of all points (x, y) in the
