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 in trial 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.
(use greater, less, or equal)
Using the data on the figure, calculate the speed of the car intrial Q. Use 340 m/s for the speed of sound
