Amy, standing near a straight road, records the sound of thehorn of a car traveling at a constant speed.
(a) The recorded frequency as a function of the car's positionalong the road for trials at different car speeds is accuratelygraphed below.
Answer Choices: G-Greater Than, L-Less Than, E-Equal To
(i) The distance of Amy from the path in S is ..... in Q.
(ii) The speed in trial S is ..... to that in Q.
(iii) The speed in trial U is ..... that in S.
(iv) The speed in trial T is ..... that in other trials.
(v) The speed in trial R is ..... that in other trials.
(vi) When the car is far away, the average of the frequenciesmoving in and out is ..... the frequency at rest.
(b) Using the data on the figure, calculate the speed of the carin trial S. Use 340 m/s for the speed of sound.
