Physics 213 Midterm Fall 2004 Form A 1. The bulk modulus is a proportionality constant that relates the pressure acting on an object to: A. the shear B. the fractional change in volume C. the fractional change in length D. Young's modulus E. the spring constant 2. Which one of the following is true of any fluid (not necessarily ideal)? A. It has a large shear modulus. B. It supports both transverse and longitudinal sound waves. C. It is incompressible. D. It is nonviscous. E. It conforms to the boundary of any container in which it is placed. 3. A sinusoidal wave of frequency 400 Hz has a velocity of 350 m / s. The distance between two points that differ in phase by π /3 rad is: A. 0.117 m B. 0.139 m C. 0.146 m D. 0.876 m E. 0.917 m 4. A traveling sound wave moves through an air filled cylindrical pipe. At a certain instant in time t and at a certain position x along the pipe, the longitudinal displacement s ( x , t ) of air is observed to be a maximum. At that same point and same instant, the pressure variation p ( x , t ) of the air is: A. a maximum B. zero C. a minimum D. somewhere between zero and a maximum, depending on the frequency of the wave. E. somewhere between zero and a minimum, depending on the frequency of the wave. Page 1
