Homework Answers
1) In table #4 main scale reading and Vernier coincidence are base measures whereas height of cylinder and main height are derived measurements.
In table #5 volume and mass are base measure and density is derived measurement. Density is mass per unit volume.(or mass divided by volume)
2) given density marble= 2.65 g/cm^3 = it must be made of primarily limestone(density=2.7 g/cm^3) with few other additives .
cylinder=1.25 g/cm^3= cylinder might be made of polycarbonate(1.3 g/cm3) or some kind of hard rubber(1.2g/cm3).
Please let me know if it was helpful. Thank you!

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.
