The atomic radius you estimated from your graph is most likely not exactly the same as the true atomic radius of tin. There is a small percent error. What do you think caused this error? There is no way to tell from looking at the graph exactly what it would be without a point. Also, the numbers do not increase at regular intervals, so you really can’t
(c) Air is made up of a mixture of gases, and is comprised of only 21% oxygen. The remaining gases would not be involved in the combustion process. On the contrary, the gases such as carbon dioxide may hinder the combustion process. Hence, if the bomb calorimeter were to be pressurised with air at 30 atm, it would result in an incomplete combustion of the fuel sample due to the lesser quantities of oxygen available. There would be a slower rate of combustion which leads to inefficient burning and less heat would be produced in the process.
EXPERIMENTAL DATA: Table 1: Measured values from experimental data Resistor Measured Value 101 Ω Capacitor 1 μF Amplitude of voltage 5v Phase difference 58.752º Peak to peak voltage 10 v Amplitude of current 2.53 mA ANSWERS TO THE POST LAB REPORT: Q. 1. Dividw the amplitude of the signal generator voltage measured by the oscilloscope by √ and compares it with the measured value by voltmeter. Answer: Here given, Vm = 5 V Dividing Amplitude of voltage Vm by √2, 5 √2 = 3.54 Comment: Both values were not matching. There have more than 10% discrepancy.
Our scale only measures to grams accurately, and could have not accurately represented the .68g of CaCO3, or we could have lost the solid precipitate in the process of the experiment. These errors could be reduced with a more accurate scale, as well as more experienced hands performing the procedure, or skilled hands, ie: we are novices at this lab, and training could produce more accurate
We have already acknowledged that Mr. Allison was not very well suited for the job. There were other issues that include technical, ethical, legal, contractual and other project management related issues. Technical Issue: The technical issue is simple, the project simply did not test well. STI simply required all components to operate effectively and efficiently between temperature ranges of -65 degrees F to 145 degrees F (The Orion Shield Project, 2003). SEC failed at this due to the fact that their product will not operate above 130 degrees F, and that the requirements would not be able to be met without different materials (The Orion Shield Project, 2003).
Despite Wegener having no concrete proof as to why this was the case his theory was proved to be accurate, physicists had believed that the earths crust was far from strong enough to be able to force itself apart. Arthur Holmes’ work on radioactivity showed that this was not actually the case. The earth was actually much hotter then previously thought and as a result much weaker. This suggested that the mantle could transfer heat by convection currents when solid. These currents could move continents laterally along the earth’s surface.
Tree possible errors have been identified in the lab. One error was the solution was not agitated enough therefore the solute did not dissolve correctly. A second error could have came from the heating plate not heating the solution to the correct boiling point. A third error could come from equipment that was a little dirty with left over residue from previous groups. The average boiling point for my trial was 101.8 ̊C and the experimental boiling point was 102.2 ̊C.
While critics could consider this to be a risky choice considering that the average reader is not statistically inclined to comprehend the meaning of numbers, numbers show not only that a significant amount of work was put into the paper but also that the authors have a strong comprehension of the subject at hand. Numbers are known to be those complex ideas because one usually associates a number with identifying or solving a problem. Physicists and Chemists work in the lab to understand how and why the world behaves the way it does and whenever a number is used in quantifying something, the value obviously required a substantial amount of thought or work to produce. In addition to this it takes even more effort to quantify a specific number to a particular subject when the subject is something as complicated as racism. By tying the use of numbers into her argument about racism, Alice makes her ideas more believable simply because numbers convey a kind of indisputable authority.
Also we thought that coiling the wire was very difficult and that it was not the wire that was the issue with why our experiment was not working. After we started to change all of the variables and our experiment still did not seem to have positive results we decided that maybe our coils were the issue. We then recoiled the wire around a smaller object and got it come up with a reaction with the multimeter. Making sure that the coils were only slightly bigger than the batter we sent the battery through the copper wire and let it sit trying to think of more ways to make this work. After letting the battery sit inside of the wire we pulled out the magnet to find it to be warm, it was not like the battery was super hot and was going to catch on fire or anything it just seemed to be warmer than it was when we inserted it to the copper coiled
This is a huge advantage because as long as the wind blows there is power to turn the blades of the rotor. However, there are some disadvantages to wind generators. Though this is rare, the blades on a wind turbine can kill birds that fly into them. Some people say that wind turbines are unsightly and that they take away from the beauty of the natural land. However, saying this does not prove a good reason not to use wind energy to generate electricity.
