Question

thanks

A truck and a motorcycle are traveling on the highway in the same direction. The truk travels at twice the speed of the motorcycle and passes the cycle. After the truck hs passed, the cyclist sounds his horn to signal the truck that he may return to the outside lane. The frequency of the motorcycle hom is 400 Hz. Mark the correct statement. The truck driver and cyclist hear the same frequency of 400 Hz. The truck driver hears a frequency higher than that heard by the cyclist. The cyclist hears a frequency of 400 Hz; the truck driver hears a frequency less than 400 Hz. The cyclist and driver frequency of 400 Hz; the truck driver hers a frequency higher than 400 Hz. Both cyclist and driverr near the same frequency, which is less than 400 Hz. The cyclist and driver hear different frequencies, both less than 400 Hz. The car in the figure is moving to the left at 35.0 m/s. The driver blows the horn so that the car continually emits a 220.0 Hz sound. The figure shows the first two regions of compression of the emitted sound waves. The speed of sound is 343 m/s. How far has the initial compression traveled when the second compression is emitted? 0.77 m 1.56 m 7.70 m 15.5 m 35.0 m
