A car is on a road parallel to a railroad track and right beside it. The car is travelling east at 30.0 m/s while a train travelling west at 50.0 m/s is approaching it. If the car honks its

horn at a frequency of 1.00 kHz, what is the wavelength of the sound perceived by a person

riding in the train?

(a) 0.235 m

(b) 0.275 m

(c) 0.294 m

(d) 0.313 m

(e) 0.344 m

the answer is 0.313m someone explain to me how to get 0.313m I can only get 0.273m

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
