mean life of muons is tau = 2.2 us = 2.2*10^(-6) s speed v = 0.945c tau' = tau*gamma gamma = 1/sqrt(1 - (v/c)^2) => gamma = 1/sqrt(1 - (0.945)^2) = 3.0574464 Hence, tau' = 2.2*3.0574464 = 6.6 micro.s --Answer (d) 6.)
Part 1 An elementary particle called a pion has an average lifetime of 2.60E-8 s when at rest. If a pion moves with a speed of 0.940 c relative to Earth, calculate the average lifetime of the pion as measured by an observer on Earth.
at rest in the inertial frame O has a length of L in that frame.
After the switch S is closed at t=0 (t=0+) Applying Kirchhoff's loop law to the loop ABCHA : +32 - Vc - 4000I1 + 9 = 0 ........(5) As Vc(0+) = 17 V.
The proper lifetime of an unstable particle is its lifetime in the particular reference frame in which the particle is at rest The expert examines the truth statements on Time Dilation.
case the means of the observed values is: x-average = (2 + 4 + 5 + 8 + 2)/5 = 21/5 = 4.2 y-average = (6 + 17 + 16 + 20 + 8)/5 = 67/5 = 13.4 (x-average, y-average) = (4.2, 13.4) If beta-0 = 2.2 and beta-1 = 4.2 then for x = 4.2: y = 2.2 + 4.2 *
Two titanium spheres approach each other head on with the same speed and collide elastically. After the collision one of the spheres whose mass is 300 g remains at rest (a) what is the mass of the other sphere?
However, we can still work on the question and calculate the point: the total fixed cost is FC=120,000+112000 = 232000 The average variable cost is AVC = $ 1.50 +0.7 = 2.2 The marginal contribution is MC=Price- AVC= P-2.2 Then at the break-even point
Research has concluded that a college graduate will earn an average of $1,000,000 more over their lifetime than someone with a high school diploma (http://www.investortrip.com/20000-reasons-why-college-is-worth-your-time/).
Ninety bulbs are selected at random, and their mean lifetime is found to be 55 months. Can we conclude, at the 0.05 level of significance, that the mean lifetime of light bulbs made by this manufacturer differs from 50 months?
