ARDMS SPI STUDY GUIDE QUESTIONS AND ANSWERS ALREADY PASSED In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? 20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes for one complete wavelength to pass a fixed poin...

Question 1 Correct 6.00 points out of 6.00 What is the internal energy of 7.91 x 1022 gas molecules at a temperature of 300 K? Select one: a. 164 J b. 109 J c. 44.2 J d. 492 J Question 2 Correct 6.00 points out of 6.00 Because the energy in SHM alternates between kinetic and potential, at some position x, the kinetic energy must be equal to the potential energy. For the general case, an object undergoing SHM with an amplitude A, which of the following is this position? Select on...
