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?

A1500 w electric heater is plugged into the outlet of a 120 v circuit that has a 20 a circuit breaker. you plug an electric hair dryer into the same outlet. the hair dryer has power settings of 600 w, 900 w , 1200 w, and 1500 w. you start with the hair dryer on the 600 w setting and increase the power setting until the circuit breaker trips. under what setting does the circuit breaker trip.
