Estimate uncertainties in length, L, and time T, measurements: L: = T= Explain how you estimate the uncertainties in measuring the length and time. Which uncertainty contributes more to the variation of your g result? Using the data from part 3, plot a graph of T vs. L1/2. (Recall that this implies that T is on the 'y-axis'). Include error (uncertainty) bars in the period data. Determine which variables control the period of a simple pendulum; Mass, Amplitude, and or Length. Determine the acceleration of gravity, g, from the slope of your graph. (See the following notes for information about how this is done. You will use this principle many times in the future.) Does your result agree with the theoretical value of 9.8 m/s2? Discuss what might be the causes of the disagreement
