Amy, standing near a straight road, records the sound of the horn of a car traveling at a constant speed. The recorded frequency as a function of the car's position along the road for trials at different car speeds is accurately graphed below. 1050 Observed Frequency, is 1000 950 900 850 800 ……….. TATA -100 - -U -50 S 0 Position, (m) 50 The speed in trial T is that in other trials. The distance of Amy from the path in R is ..... in S. The speed in trial Q is ..... that in other trials. 100 When the car is far away, the average of the frequencies moving in and out the frequency at rest. The speed in trial U is ..... that in S. The speed in trial S is ..... to that in R. Using the data on the figure, calculate the speed of the car in trial U. Use 340 m/s for the speed of sound.
