2015 F = ma Exam — Question 19

The following information applies to questions 19 and 20 A U-tube manometer consists of a uniform diameter cylindrical tube that is bent into a U shape. It is originally filled with water that has a density ρw. The total length of the column of water is L. Ignore surface tension and viscosity. 19. The water is displaced slightly so that one side moves up a distance x and the other side lowers a distance x. Find the frequency of oscillation.
