Consider propagation of neutrinos (produced in the interaction of cosmic rays with air ) through the earth. what fraction of neutrinos with energy 10 gev will be absorbed when passing through the earth's center. hint: the fraction is very small so you can use the taylor series expan- sion for n )no exp(x) to calculate probability of interaction. to perform the calculation use the particle data book on the web (see syllabus for pointer) to find the plot for neutrino - nucleon cross section. use radius of the earth from the web and take average density of the earth equal 6 g/cm3 to calculate cross section of interaction with nuclei in the media treat the media as a collection of free nucleons

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

u can delete ur account.

1. go on google and write

2 open this and click on your profile pic and if your profile is not appearing, then u have to log in.
