It is quite likely that in your calculations from Part A resulted in a non-zero percent error. This is somewhat expected in experimental work. Consider the possible sources of error/discrepancies that might have occurred between our theoretically and experimental moment values. Which do you think are non-negligible (ie had a measurable influence on your results). *Please note, multiple answers can be chosen. Right answers are worth 1 mark, wrong answers chosen result in -1, 0 marks awarded when left blank. This is to discourage you from randomly choosing answers or selecting all. U a. The density of the dye was not considered in your calculations (J b. The weights provided were not accurate. U c. Observation errors when taking measurements (J d. The quadrant tank was not appropriately levelled before measurement Q3. Given your results from above, calculate the (absolute) percentage error of the experimentally measured () moment about the centre of rotation compared to the theoretical () moment. Provide your answer to 2 decimal places (ie 5.23). Do not include the percent sign in your answer. For Full 1 MError_1 =|17.71 Your last answer was interpreted as follows: 17.71 For Full 2 MError_2 =|18.12 Your last answer was interpreted as follows: 18.12
