For this discussion, review your readings for Module 6.1. You must complete your post before you can see what other students have posted. In your post include the following: 1. Describe what are the Physics principles "behind" the ultrasound machines used in medical diagnostics? Use full and complete sentences in your answer. 2. Use the values for density and the speed of ultrasound given in College Physics: Chapter 17 Section 7>Table 175. and calculate the acoustic impedance of blood and bones. 3. Compare your results with those provided in Table 17.5. and answer the following question: are your values close to those given? Explain your answer and show your calculations. Use the D2L Math Editor if necessary. 4. Conclude by saying what you learned from this exercise.
