1. In calibrating a 10-mL pipet, a measured volume of water was transferred to a tared flask and weighed, yielding a mass of 9.9814 g. (a) Calculate, with and without correcting for buoyancy, the volume of water delivered by the pipet. Assume that the density of water is 0.99707 g/cm3 and that the density of the weights is 8.40 g/cm3.

Explain. 2. Repeat the questions in problem 1 for the case when a mass of 0.2500 g is measured for a solid that has a density of 2.50 g/cm3. 3. Is the failure to correct for buoyancy a constant or proportional source of determinate error?
The air resistance to the motion of a vehicle is something important that engineers investigate. As you may also know, the drag force acting on a car is determined experiementally by placing the car in a wind tunnel. For a given car, the experimental data is generally represented by a single coefficient that is called the drag coefficient. It is given by the relationship C(4)=F(d)/ 1/2 pV^2 (A) C(d)= drag coefficient F(d)= measured drag force (lb) p= air density (slugs/ft^3) V= air speed inside the wind tunnel (ft/s) A=frontal area of the car (ft^2) What is the appropiate unit for C, if the proceeding equation is to be homogeneous in units? show all steps of your work
