- Plz do fast, it is urgent, i m waiting for your answer, vll rate high ...A positive K meson (K+) is an unstable subatomic particle that decays into other particles. At rest, its mean lifetime is 1.23 x 10-8 s. (a) What do you measure the mean lifetime of a K+ to be if it is moving at 0.800c relative to you? (b) As measured from the reference frame of this K+, what is the mean lifetime of a second K+ that is at rest relative to you?The lifetime of a muon is 2.20 ?s. If you measured its mass to be 105.7 MeV/c2, what would be the minimum (Heisenberg) uncertainty in this value? Sketch the situation, defining all of your variables

Assuming the motion of the galaxies is due to the Hubble flow, determine the value of the Hubble constant, Ho. Show how the value of Ho can be used to estimate the age of the Universe, describing any assumptions that you make. Use the value of Ho you have obtained to estimate the age of the Universe, expressing your answer in Gyr.A.

- Near the center of our galaxy, hydrogen gas is moving directly away from us in its orbit about a black hole. We receive electromagnetic radiation of wavelength 1888 nm and know that it was 1875 nm when emitted by the hydrogen gas. Randomized Variablesλ = 1888 nm What is the ratio of the speed of the gas to the speed of light?Which of the following statements are IMPOSSIBLE? Choose all that apply. The rocket's speed was measured to be 1.02c. ASK YOUR TEACH The rocket's rest length is 847 m. An observer flying by measured the rocket to be 173 m long. A rocket flying by the Sun at 0.48c measured the speed of the photons (particles of light) emitted by the Sun to be 0.79c. An inertial reference frame had an acceleration of 0 m/s². The proper time interval between two events was measured to be 296 s. The time interval between the same two events (as measured by an observer not in the proper frame) was 3702.9. (a) Solve the integral ...| (dx .dx3N) 3N and use it to determine the "volume" the relevant region of the phase space of an extreme relativistic gas ( = pc) of 3N particles moving in one dimension.
