Question: A quality assurance engineer at a frying pan company is asked to qualify a new line of nonstick-coated frying pans. The coating needs to be 1.00 mm thick. One method to test the thickness is for the engineer to pick a percentage of the pans manufactured, strip off the coating, and measure the thickness using a micrometer. This method is a destructive testing method. Instead, the engineer decides that every frying pan will be tested using a nondestructive method. An ultrasonic transducer is used that produces sound waves with a frequency of f = 25\ \text{kHz}. The sound waves are sent through the coating and are reflected by the interface between the coating and the metal pan, and the time is recorded. The wavelength of the ultrasonic waves in the coating is 0.076 m. What should be the time recorded if the coating is the correct thickness (1.00 mm)?

Question: Critical Thinking A car travels around a loop with negligible friction at a constant speed and never loses contact with the loop. The top of the loop is labeled A and the bottom of the loop is labeled B. (a) At what point would the normal force be greatest? Briefly explain your reasoning. (b) Based on experimental data, an equation that fits the data is suggested for the normal force, _FN_ , which may not be correct: F_{N} = Kr^{1/2} , where _K_ is a constant with appropriate units and _r_ is the radius of the loop. Is this equation consistent with your answer from part a? Explain why or why not. Does this equation make sense? Explain why or why not. (c) Now the car travels around loops of various radii and the speed at which the car barely makes it around the loop is measured. Graph that speed vs. the radius of the loop.
