There are known numerical values that are not subject to fractional error, and therefore do not affect the number of significant figures in a calculation. These are called “exact numbers.” Some examples include: 1 foot = 12 inches, 100 years in a century, 2.54 cm in an inch. Therefore, if a number is considered exact, it does not affect the accuracy of a calculation. When taking significant figures into account for a problem, exact numbers will not affect them either. When performing a measurement on a digital instrument, read and record all of the numbers as displayed, including zeros after the decimal point. But on a scaled instrument, estimate one more figure than you can actually read from the scale. This accounts for the inaccuracies and errors that occur naturally. Accuracy is “a measure of the deviation of the measured value from the true or accepted value.” Precision is “a measure of the agreement of experimental measurements with each other.” Significant figures relate to precision rather than accuracy. The more precisely a measurement is performed, the more significant digits one can have. If given a measured value, assume that the number of digits given reflect the precision of the measurement. When given a value, the answer cannot be more precise than the data that is…

Introduction As a figure skater with an enthusiasm for figure skating for many years, my choice of investigation for my internal assessment came to me quite easily. I have been a figure skater for eleven years and during this period I have been able to deepen my knowledge of the relationship between body coordinates and movements/positions of figure skating. I will be investigating the relationship between the body’s initial and interim positions and the outcome of a figure skater’s trajectory…

Significant figures are the numbers that are important when performing calculations in chemistry and other fields of science. These numbers are important to scientists because they determine the accuracy and precision to which their measurements and calculations were made. Significant figures are important to the scientific method because the results of experiments that are performed to test hypotheses can be altered due to mistakes of significant figures. Measurements are only as accurate as…

I come from a figure skating background. From a very young age, most of my time was spent at the rink. Growing up, I undoubtedly spent more waking hours with my skating coach than with my own mother. This cold damp place was home. It is where I trained, ate, did school, socialized, laughed, cried, and even took the odd nap. It was as familiar as my favourite pair of lucky socks (yes, us figure skaters are very superstitious). I knew the best hiding spots, for when I needed time alone or…

Figure skating is a sport in which single athletes or teams of athletes conduct artist performances on ice. The objective of the sport is to score the highest marks possible from the judges, in order to get points athletes are required to perform a number of different moves, they perform a selection of spins, jumps, lifts and steps depending on the nature of the event. Skaters may use professional music editors so that their music meets requirements; they are required to skate to music that…

African sculpture is most often figurative, representing the human form. It is primarily fashioned from wood. The African sculpture can be described as monumental, meaning that the figure or form is not separated from the wood in which it is carved, which gives is a feel of heavy permanence. These aspects are visible in the African sculpture, Figure of Bena, Mboi, Yunger people in Nigeria 14th-16th century, Nigeria, Eastern Gongola Valley, and Figure of the Jukan people 19th-early 20th century,…

Yet upon a second more detailed examination, traditional elements of composition began to appear. In the center of the piece, there is an identifiable pyramidal structure of the figures, with the reclining nude upon the boot at the base, the three figures, Mary, Jesus, and the contemplative apostle in the back, making up the body of the pyramid, and sun-ring at the top. Vanity and lust fall below qualities of compassion and wisdom, which ultimately is under godliness and piety. Another…

The Flower Girl. As with many of Vyse’s figures, names were often changed. The autumnal sprays in the basket, may have been the cause of the re-naming the figure Autumn Leaves. This is a quintessential Vyse figure, illustrating the reality of the social background from which the flower selling women sprang. The outdoor life in all weathers doubtlessly gave the women, their ruddy and weathered features, so unlike the pale creamy complexions of their Vyse counterparts. Moreover, Vyse is saying to…

role in how the main character would struggle to find who he was as a person and what kind of potential he obtained emotionally as well as educationally. Between his father, mother, and closest the protagonist had no one to express himself to. The main character recollects “He handed me a gift, a book, and after he was gone i threw it away, didn’t even bother to open it…” (Diaz 433). He was so jealous of Beto that he chose to leave him in the past and not open his gift that he felt was to…

waited in that theatre room for days, anticipating the competition to come. waiting thirty minutes to preform isn't everyone's cup of tea, but the long minutes that dragged on made me anxious. When they called for us my heart skipped a beat. I could feel my hands clam up and my my breaths grow more ragged. I wasn't ready for it. Not now. Not yet. It was the most frightening moment of my life, but when we started acting it all went away. I felt calm and excited. When we finished I felt very good,…
