Can someone please help me with the questions for my Physics Lab? If someone can help me out with the questions, that would be really great.

Overall, were your densities precise or imprecise? Justify your answer. 2. Overall, were your densities accurate or inaccurate? Justify your answer. 3. The first three submerged objects in today's experiment were identical to the three objects used in the "Measurements" experiment. Referencing the percent errors from that previous experiment, is the method used in today's experiment more or less accurate in comparison? 4. Why is the method used in today's experiment generally more useful than the method used in the "Measurements" experiment? Hint: Consider the fourth submerged object. 5. Identify the independent variable(s) for this experiment. . Be specific and use proper vocabulary. 6. Identify the fixed variable(s) for this experiment. . Be specific and use proper vocabulary. 7. Identify the dependent variable(s) for this experiment. . Be specific and use proper vocabulary
