Photon Ranking Task


The following six particles (with rest energy and kinetic energy as indicated) are collided with their antimatter partners traveling in the opposite direction with the same kinetic energy. The resulting matter-antimatter annihilation produces a pair of photons traveling in opposite directions.


Part A
Rank these particles on the basis of energy of the photons they create.

Rank from largest to smallest. To rank items as equivalent, overlap them.
Part B
Rank these particles on the basis of speed of the photons they create.
Rank from largest to smallest. To rank items as equivalent, overlap them.
E_0=200 MeV/K=400 MeV
E_0=400 MeV/K=200 MeV
E_0=800 MeV/K=100 MeV
E_0=100 MeV/K=200 MeV
E_0=100 MeV/K=400 MeV
E_0=200 MeV/K=100 MeV

Small dust particles suspended in air seem to dance randomly about,a phenomenon called Brownian motion.

For this problem you will need to know Boltzmann's constant: k_{\rmB}=1.38\times10^{-23}\;{\rm J/K}.

A) What would you expect the mean translational kinetic energy K ofsuch particles to be if they are in air at a temperature of 290K?
Express the mean translational kinetic energy numerically, injoules, to two significant figures.


B) Find an expression for the rms (root-mean-square) speed v_rms ofthese particles, assuming them to be spheres of diameter d anddensity rho.

Condensation nuclei, tiny particles of matter in the air, are important because ________.

A) they increase the density of air and thus its buoyancy
B) they provide a surface for water molecules to form on
C) they provide point sources of heat in the air
D) they will affect the environmental lapse rate
