Charge Baryon Lepton Strangness
45
How to work out how much rest energy there is?
E = m c^2
46
What is annihilation?
When a particle and there respective antiparticle collide they destroy each other and all mass is converted into energy in the form of two photons?
47
A Proton turns into a neutron what are the byproducts of this type of decay?
A positron and an electron Neutrino
48
What happens in beta minus decay?
A neutron decays into a proton and a beta minus/ electron is released with an anti electron neutrino
49
What happens when to electrons get close?
A virtual photon carries the electromagnetic force and caused them to repel
50
What is the symbol u mean ( not up )
Muon
51
At what distance is strong nuclear stronger than weak nuclear ( electrostatic)
Between 0.5 and 3 femptometers
52
What happens in the strong interaction between a proton and neutron?
A Proton and neutron are attracted by the strong nuclear force with the exchange of a neutral charged pion
53
What happens in the electromagnetic interaction between two electrons!
The two electrons repel with the exchange of a (virtual) photon
54
What happens in beta minus decay?
A neutron decays into a proton and due to the weak interaction (w^-) an electron and anti electron Neutrino is released
55
What happens in beta plus decay?
A Proton decays with the weak nuclear force (w^+) into a positron and an electron Neutrino
56
What is the properties of the k + meson
+1 charge 1+ strangness
57
What is the difference of a kaon and pion?
Kaon is strange and pion isn't
