Can someone please help me with these questions,

I would really really appreciate; I am so confused in how to answer these questions and I could use some help please

Feel free to make up numbers if needed but please take a look at the lab manual before so

I have attached it as well.

Here is the lab manual

B Ray Diagram Ray diagrams are used to provide some qualitative answers and intuition about the behavior of thin lenses and mirrors, however a carefully drawn diagram can give surprisingly good quantitative results. Draw a scale drawing of a ray diagram for one of the trials in Activity 1 and compare the graphical computation to the actual image distance. 1. Choose one of the trials from Data Table 1 to determine the appropriate scale for the diagram. Calculate the sum of the object and image distances from the selected trial to determine the entire size of the experiment. 2. Divide the sum by the length of the longest side of a blank sheet of paper, and then round this number up to the nearest whole number. This whole number represents how many centimeters in the actual experiment are equal to 1 cm on the sheet of paper. This is the scale that will be used to create the diagram and can be represented as a ratio (for example, 2:1).3. Orient the paper lengthwise. Near the left 6.
