An incompressible fluid is flowing through a pipe with a constriction. The pipe is on an incline with an angle of 30.0 degrees. The narrow section is 10.0 m from the wide section and the narrow section is lower than the wide section. The velocity of the fluid in the wide section of the pipe is 4.00 m/s. The diameter of the wide section is 12.00 cm and the diameter of the narrow section is 9.00 cm. The pressure of the fluid in the wide section is 250 kPa. What is the pressure in the narrow section of the pipe? (density of the fluid is 1,000 
A. 295 kPa B. 282 kPa C. 275 kPa D. 252 kPa E. 240 kPa
Motional Emf: An electromagnetic flowmeter is useful when it is desirable not to interrupt the system in which the fluid is flowing (such as the blood in an artery during heart surgery). Such a device is illustrated in the figure. The conducting fluid moves with speed v in a tube of diameter d. Perpendicular to this tube is a magnetic field B. A voltage V is induced between opposite sides of the tube due to the motion of the conducting fluid in the magnetic field. For a certain case, B = 0.120 T, d = 1.2 cm, and the measured voltage is 10-3 = 2.88 mV. Determine the speed of the fluid. 
A. 2.0 m/s B. 11 m/s C. 0.075 m/s D. 1.1 m/s E. 750 m/s
A method of expressing the accuracy of measured quantities is
a. metric prefixes. b. derived units. c. significant figures. d. conversion factors.
You are heating a jar full of hydrogen and observing its spectrum. When you add more hydrogen to it, what happens to the spectral lines in the spectrum?
A. The positions of emission lines will change. B. The positions of emission lines will remain the same, but the lines will get broader and brighter. C. You will start seeing lots of absorption lines instead of emission lines. D. There will be no change in the spectrum.
