PSC 2121 Lecture Notes - Lecture 5: Transverse Wave, Atomic Nucleus, Einsteinium
Document Summary
The beam of neutrons, however, is less harmful. Give a possible explanation: the neutron is nearly massless, the neutron is only slightly more massive than the proton, the discovery required the use of ultrafast computers, the neutron lacks an electrical charge. Physical science psc2121: boron has primarily two isotopes, one with an atomic mass of 11 amu and another with an atomic mass of 10 amu. If the abundance of the boron atom with a mass of 11 amu is. 11amu- 18. 9: 10. 19 amu 10amu- 81. 1, 11 amu 18. 9*11+ 81. 1*10=1018. 9 . (10. 19, 10 amu, 10. 81 amu, not enough information given, calculate the de broglie wavelength for an electron (m = 1 10. 6 m/s: 1. 7 10 10, 2. 2 10 10 m m.
