Joe, 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 1050 graphed below. (ZH) Observed Frequency, 1000 950 900 850 800 -100 -50 u 0 Position, (m) 10 The speed in trial U is ..... to that in Q. The speed in trial R is ..... that in S. The speed in trial S is ..... that in other trials. The distance of Joe from the path in Q is ..... in U. The speed in trial T is ..... that in other trials. When the car is far away, the average of the frequencies moving in and out is ..... the frequency at rest Submit Answer Tries 0/12 Using the data on the figure, calculate the speed of the car in trial Q. Use 340 m/s for the speed of sound.
