[8 marks] This measured mass of the ruler M is considered as the actual mass of the ruler. Data for mass 1/m (kg^-1) and distance L (meters) (Note: mgXL =0.2 x Mg ] 0.35 0.3 For all the masses, record your measurements in table 1 below. y =0.0227x +0.0028 0.25 Mass, m Distance _ cm Average L 1 / mass kg L L3 m 0.2 distance L (meters 80g - 0.08 28.6 28.6 28.6 0.286 12.5 0.15 90g - 0.09 25.5 25.5 25.5 0.255 11.1111 01 100g - 0.1 23 23 23 0.23 10 0.05 110g -0.11 20.8 20.8 20.8 0.208 9.0909 120g - 0.12 19.1 19.1 19.1 0.191 8.3333 2 6 8 10 12 14 mass 1/m (kg^-1) 130g - 0.13 17.8 17.8 17.8 0.178 7.6923 Table 1: Data for mass m (kg) and distance _ (meters) Graph Using Microsoft Excel or MATLAB, draw a graph of length L in meters (on y-axis) against m (kg-1) (on x-axis). Label your axes with the correct quantities and correct units. o Use Excel or MATLAB to find the equation of the best-fit line. Equation: y = 0.0227x +0.0028 [1 mark] o Record the gradient (slope) of your line. Gradient (slope) of the line: Slope = 0.0227 [1 mark]Analysis, evaluation, and conclusion 4. Calculate the percentage error of your experimental value for the mass of the meter ruler compared with the 0.2M actual mass of the meter ruler. [2 marks] 1. Use the principle of moments to find _ = - , where M is the mass of the meter rule in kg. (You will get m the approximate result [3 marks] (Show for one trial) % error = Jexperimental value - Actual value x 100% actual value 2. Considering the trend followed by your data points explain if your data agrees with your hypothesis. [3 marks] 5. In this experiment, you used an analogue meter ruler. What type of errors does this introduce in to your readings? Explain how we could minimize the effect of this type of errors. Considering the trend followed by your data, points explain the possible error also. [2 marks] 3. Using the slope (gradient) of your graph find the mass of the meter ruler. [2 marks] 6. Write a brief conclusion for your experiment. [3 marks]
