Two scientists Mukund and Veronika do the experiment with a speaker which generates the sound wavesof frequency 150 Hz. Both are at rest and Mukund throws the speaker, which emits the sound waves, to Veronika who measures the frequency 160 Hz (before catching the speaker). The speed of sound isapproximately 350 m/s. a) How fast did Mukund throw the speaker (e. g. what is the speed of the speaker)

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
