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)? 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: 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

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
