One complete turn of the revolving scale that has 20 divisions makes one smallest division on the main scale. What is the smallest possible reading that can be obtained? . Compare the values of different readings as well as the computed values of density and volume using different measuring devices such as the micrometer, vernier, and metric ruler. Which one has an accurate reading? What must be the reason why one should be aware of the room temperature reading? CONCLUSION: 1. In yam general observation, what is the difference between the fundamental quantities and derived quantities
