You had an appointment with your family physician. This physician just happens to dictate reports to the medical transcription company that you work for, and you are one of the MTs who work on that site. You go into the system at work and open up the report to see who transcribed your report and to the report. Is this in violation of HIPAA? Yes or No

A cylindrical pipe, closed at both ends, contains air molecules, where the speed of sound is [v] m/s. When the pipe resonates, it forms a standing sound wave inside. The figure shows a snapshot of the standing wave with a wavelength of [lamda] m. When the air in the pipe resonates at its fundamental frequency, calculate the fundamental frequency in hertz (Hz).

A 2.4 kg particle undergoes horizontal oscillation at the end of an ideal spring. The displacement-time graph of its motion is shown in the figure. A = [A] m and t3= 0.2 s. Determine the positive displacement x of the particle when it has one‑third of the maximum speed. Express your answer in meters.

A [m] kg particle oscillates horizontally at the end of an ideal spring. The displacement-time graph of its motion is shown in the figure. A = [A] m and t3= [t3] s. When the particle is located at 50% of the amplitude from the equilibrium position, determine its kinetic energy (K) in joules. [Hint: frequency can be determined from the time-displacement graph.]

A mass is attached to a horizontal ideal spring, undergoing simple harmonic motion. The displacement amplitude is A = [A] m. At a certain time t, the potential energy stored in the spring is [E1] J, and the kinetic energy of the mass is [E2] J. Determine the maximum magnitude of the spring force exerted on the mass (in newtons). [Hint: the maximum force in SHM is Fmax = k × A.]
