Answer 1

Answer:

oh u can download Microsoft maths solver and Khan academy

both are absolutely free and very helpful

When further studies showed that these particles were positively charged, the assumption was that these particles were positively charged electrons, positrons, examples of which had recently been discovered in the cosmic rays. By 1940 it was becoming apparent that the majority of the incident particles were not electronic but nuclear, presumably protons. It is now known that although most of the particles are indeed protons, there are also energetic nuclei of all the elements in the periodic table present with roughly the same abundance as those found in the solar system.

These particles originate from outside the solar system, although, in addition, the sun sometimes produces bursts of copious but relatively low energy particles, solar energetic particles (SEP). The energies of the cosmic ray particles cover an enormous range, from values typically found in radioactive decays, 106 electron volts (eV), to greater than 1021 eV, energies that are greatly above any that can be produced in the largest accelerators made by humans.
