Question

the speed of sound in gelatin and fatty

5. The speed of sound in gelatin and fatty tissue is 1530 m/s. The graph shows the amplitude (in micro meters) of an ultrasonic wave traveling through the tissue versus time (in mi Part 1: What is the wavelength of this wave? Part 2: What is the angular velocity of the wave? y (106 meters) A) 3.1 mm and 126 u radians/second B) 3.1 mm and 3.14 M radians/second C) 3.1 mm and 9.6 k radian/second D) 7.65 mm and 12.6 i radians/second E) 7.65 mm and 3.14 M radians/second F) 7.65 mm and 9.6 k radian/second d's 05152535/45 's a' 3' s IIIII 1 1 (10 Seconds) 6. An ultrasonic wave has an amplitude of 1x10 meters, a frequency of Ix10 Hertz, and travels in the positive x direction at 1500 meters/second. How would the wave be desc equation form A)y=1 um sin (6.3x10$-4.2x10>> B) y a 1 um sig (63x10% +42x10%) C)y1 um sin (1.0x10 - 4,2x10) D) y l a sin (1.0x1061+4,2x1024 E)y=1 um sin (63x10-1.5x104x) Fy=1 um sin (6,3x10% +1.5x10)
