For Homework No. 2: Study the following problem No. 70 accompanied by a table Using the mass , dimensions and formula for solving volume of drical object, find the experimental values for densities of ide tals . mate the mass of a cell that has a diameter of 1.0 um, a minum, copper, brass, tin, and iron. Use these data to human kidney, and a fly. Assume that a kidney is calculate the densities of these substances. Compare roughly a sphere with a radius of 4.0 cm and that a your results for aluminum, copper, and iron with those fly is roughly a cylinder 4.0 mm long and 2.0 mm in given in Table 1.5. diameter. 69.
