Amy, standing near a straight road, records the sound of thehorn of a car traveling at a constant speed. The recorded frequencyas a function of the car's position along the road for trials atdifferent car speeds is accurately graphed below.
1. The speed intrial T is ..... that in other trials. 2. The distance of Amy from the path in R is ..... in U. 3. The speed in trial S is ..... that in R. 4. The speed in trial R is ..... to that in U. 5. When the car is far away, the average of the frequencies movingin and out is ..... the frequency at rest. 6. The speed in trial Q is ..... that in other trials.
