Measurement of Density Lab
Consider the uncertainty in the measured value of rho to be given by alpha_rho. Taking the one decimal place of alpha_rho as the least significant digit in rho, how many significant figures are indicated for each of the measurements of rho? What is the accuracy of your determination of the density for each metal? State clearly what quantity describes the accuracy of your measurements of the density. Consider the value of the standard error alpha_rho as...

Two engineers must measure the distance between the McGill metro station to the athletic centre to build an underground tunnel. One engineer finds that the distance is 9134 ± 5m while the other finds that the distance is 9150 ± 20m. In what ways can they compare their measurements? Do their measurements agree? Explain....

A laboratory measurement of the coordinates of the ends of a moving meterstick, taken at the same time in the laboratory, gives the result that one end of the stick is 0.9918 m due north of the other end. If the stick is moving due north, what is its speed with respect to the lab?
