Problem 67P The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is nonpolar because the bond polarity is canceled by the symmetric tetrahedral shape. When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes polar. Use Figure 9.20 (p.

Three apprentice tailors (\(X\), \(Y\), and \(Z\)) are assigned the task of measuring the seam of a pair of trousers. Each one makes three measurements. The results in inches are \(X\) (31.5, 31.6, 31.4); \(Y\) (32.8, 32.3, 32.7); \(Z\) (31.9, 32.2, 32.1). The true length is 32.0 in. Comment on the p

A flat piece of glass covers the top of a vertical cylinder that is completely filled with water. If a ray of light traveling in the glass is incident on the interface with the water at an angle of ua = 36.2, the ray refracted into the water makes an angle of 49.8o with the normal to the interface.
