A narrow beam of ultrasonic waves reflects off the liver tumor in Figure. The speed of the wave is 10.0% less in the liver than in the surrounding medium. Determine the depth of the tumor. 12.0 cm 50.0° Liver– Tumor

Is Sandy correct that the moving man did not return to his starting location?   First find area. Then solve the problem by filling in the squares and triangles with the correct meters. Then add all the meters together on both sides. One side should be positive the other negative. Does the final meters add up to 0? If not the man did not return to his starting location. Show all work on the graph.

HELP FILLING IN BLANKS IN THE PROCEDURE. Procedure 4: Adding Vectors Graphically If you use a ruler and a protractor to draw a series of vectors to scale, the resultant will run from the beginning of the first vector to the end of the last vector.  In the picture below, measure the lengths and angles of vectors A, B and C and record these in the 2nd and 3rd columns on the datasheet. Remember to measure angles CCW from the positive x axis. Using cos and sin, calculate the x and y components of vectors A, B and C and record these in the last two columns on the datasheet. Add the x components in the next-to-last column and the y-components in the last column  Use Pythagorean Theorem and ArcTan to calculate the magnitude and direction of R Measure the length and angle of vector R Confirm that these two measurements of R match   "Fixing the angle" After you do the "four step method" to add vectors, you sometimes have to "fix the angle". Remember that we always start…

please help ASAP (& pls draw a picture), thank you!
