Raymond davis jr.’s neutrino detector contained approximately 1030 chlorine atoms. during his experiment, he found that one neutrino reacted with a chlorine atom to produce one argon atom each day.
how many days would he have to run the experiment for 1% of his tank to be filled with argon atoms?
convert your answer from a. into years.
compare this answer to the age of the universe, which is approximately 14 billion years (1.4 × 1010 y).
what does this tell you about how frequently neutrinos interact with matter?

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
