A student measures distance x to be 5 meters and area A to be 25 ft2. Which of these statements is true? A.[x2] = [A] B.[5x] = A C.x2 = [A] D.x2 = A E.None of these Ans A For a spherical alveolus of radius 100 μm, which is larger? Ans Not sure The diffusion constant D, describes how molecules jiggling around in a fluid drift. It has dimensions[D] = L2/T We have good reason to believe (we'll see it in a reading later) that D depends on the average distance a mole...

A student (with a "rubbed" nail in her hand) sees another nail floating in a pan of water and decides to test to see whether is "rubbed" also. She holds the tip of the "rubbed" nail to the tip of the floating nail (as shown) and sees that there is an attraction between them. What can she concluded from just this observation? Ans It is not possible to say whether the floating nail has been rubbed or not. The South Pole of a bar magnet is slid across a nail from it...
