The z0 boson, discovered in 1985, is themediator of
the weak nuclear force, and it typically decays veryquickly. its
average rest energy is 91.19 gev, but its shortlifetime shows up as
an intrinsic width of 2.5 gev (rest energyuncertainty). what is the
lifetime of this particle?

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?

9.98 kg of r-134a at 300 kpa fills a rigid container whose volume is 14 l. determine the temperature and total enthalpy in the container. the container is now heated until the pressure is 600 kpa. determine the temperature and total enthalpy when the heating is completed. use data from the steam tables.

What property of an object determines its inertia?
