1. Which object has the most accurate determination of the density of the material? Show clearly how you determine the accuracy of your evaluations of the density. (1 point) 2. Which object has the most precise determination of the density of the material? Show clearly how you determine the precision of your evaluations of the density. (1 point) 3. Which object has the most accurate measurement of M? Explain. (1 point) 4. Which object has the most precise measurement of M? Explain. (1 point) 5. Which object has the most accurate measurement of L? Explain. (1 point) 6. Which object has the most precise measurement of L? Explain. (1 point) 7. Based on the values of the uncertainties for M and L (and the formulas for yy and y₂), which one do you think was contributing more to the uncertainty in the density? Explain. (1 point) 8. Based on your experimental data, which one between M and L most affected the accuracy of the density? Clearly state your reasoning (hint: what assumption have we made?). (1 point) 9. Can you suggest an altemative experimental method to evaluate the density and what would its advantage be?
