I am having quite a bit of trouble with this question, the problem is I don't really know where to start. I feel once i get on the...
Thanks for the help.
So I took the area of the earth, by using the radius and using the equation above. Then like in the dartboard example half the darts would hit the top half of the dart board, so whatever percentage that the body is of the total area of the Earth would be the same percentage...
Supernova Shelton 1987A, located about 170 000 ly from the Earth, is estimated to have emitted a burst of neutrinos carrying energy ~1046 J. Suppose the average neutrino energy was 6 MeV and your body presented cross-sectional area 5 000 cm^2. To an order of magnitude, how many of these...
