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?

Describe the function of the endomembrane system? what organelles are involved?

If element x has 99 protons how many electrons does it have

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
