Question
One type of these events whose name arises from charged particles interacting in their own electric field results in trajectories that follow a hyperbolic Keplerian orbit. For 10 points each:
[10m] Name these events that are assumed to be absent in diffuse, high temperature plasmas. The average distance between these events is much smaller than the length scale in plasmas where these events dominate.
ANSWER: collisions [accept, but DO NOT REVEAL, Coulomb collisions]
[10e] Collisions in plasmas that occur through field interactions are named for this scientist. The inverse-square law for the electrostatic force between charge carriers is named for this scientist.
ANSWER: Charles-Augustin de Coulomb [accept Coulomb’s law or Coulomb collisions]
[10h] Time-evolution of collisional plasmas can be modelled using the Vlasov equation, which describes collisional plasmas, combined with this other equation also named for a Russian physicist, which incorporates Coulomb collisions.
ANSWER: Landau kinetic equation
