In each measurement, and the average value of D. from its three resulting values:
d" (in mm) l" (in mm)
D=(d/l)*150,000,000 km

don't average data)
In the table above, in the first measurement taken at 3:10pm, the value of d is 55.7 mm, while l is 5,998 mm. Substituting these values to the derived formula for D, which is D = (d/l) L, we get D = (55.7mm/5,998mm)(150,000,000km), or D = 1,392,964.32km. For the second measurement taken at 3:20pm, the value of d is 56.25mm, while l is 6,000mm. By substitution, D = (56.25mm/6,000mm)(150,000,000km), or D = 1,406,250km. For the last measurement taken at 3:30pm, the value of d is 56.6mm, while l is 6,003mm. By substitution again, we get D = (56.6mm/6,003mm)(150,000,000km), or D = 1,414,292.85km. The average value of D. can be taken by adding the values of D. from the three measurements in the experiment, and then dividing its result by three. In mathematical terms it translates: D = (D1 + D2 + D3)/3. By substituting the values of D. from the table above to this formula, we have D = (1,392,964.32km + 1,406,250km + 1,414,292.85km)/3, or, equivalently, D = 1,404,502.39km. Therefore, the diameter of the sun is approximately 1,404,502.39km.
In this experiment, I have learned how...
There is proper way of using Sucromates. Firstly, we need to shake it well before use. One dose accounts for 1 ml of Sucromate, which is to be injected 48 hours before desired ovulation. Sucromate Equine is a suspension of deslorelin and so with the passage of time it will settle down (Equine, pg. 9). Therefore, for this we need to warm the product for atleast 2 minutes so
Bee Behavior Bees are flying insects that perform an important role in pollination of plants, as well as the production of honey and beeswax. There are over 20,000 species of bees in nine families, but classified as Anthophila. Bees are found in every continent except Antarctica, and have adapted for the feeding on nectar and pollen as a high-level energy source, with pollen being used as food for larvae in the
Enzymes 1. How does temperature affect enzyme function? Every enzyme demonstrates maximum activity at a particular temperature known as its optimum temperature. Generally, all enzymes are inactivated at temperatures below 10°C and get denatured (lose its three-dimensional protein nature) above its optimum temperature (Seager & Slabaugh 2010). Experiments conclude that enzyme activity increases by almost ten percent coupled to each degree rise in temperature until it reaches its optimum state and declines beyond
In this exercise, I examine a public park, specifically one corner of the Crotona Park Nature Center measuring 50 feet by 50 feet, with an aim of making a number of observations within the selected area. In so doing, I will be seeking to describe what is growing in the said area. More specifically, I will not only identify the trees present, but also identify the ground cover of the
This significant difference in the findings was attributed to the fact that smoke particles tend to coagulate together into larger particulates as they age. According to Lougheed, "This suggests that the aging of smoke occurs more rapidly than might be expected; in ductwork it occurs predominantly within the first few metres" (p. 3). The analysis of the HVAC air filters indicated that there were some specific considerations that should be
Small fires, on the other hand, are less intense, and therefore cause less damage to the pine. The low air temperature in many areas of shortleaf pine growth help the heat of the fire dissipate, and therefore, more fire is required to raise the temperature of the plant cambium to the point of killing the tree. Also, if debris on the ground is only dry on top, but has
