Textbook Question
Chapter 2, Problem 102P
Quasars are among the most distant objects in the universe and are moving away from us at very high speeds, as discussed in Chapter 16. Astrophysicists use the redshift parameter z to determine the redshift of such rapidly moving objects. The parameter z is determined by observing a wavelength λ′ of a known spectral line of wavelength λsource on Earth; z = Δλ/λsource = (λ′ − λsource) /λsource. Find the speed of two quasars having z values of 1.9 and 4.9.

- The average lifetime of a pi meson in its own frame of reference is 2.6 × 10−8 s. If the meson moves with a speed of 0.95c, what is (a) its mean lifetime as measured by an observer on Earth and (b) the average distance it travels before decaying, as measured by an observer on Earth?arrow_forwardFigure P9.21 shows a jet of material (at the upper right) being ejected by galaxy M87 (at the lower left). Such jets are believed to be evidence of supermassive black holes at the center of a galaxy. Suppose two jets of material from the center of a galaxy are ejected in opposite directions. Both jets move at 0.750c relative to the galaxy center. Determine the speed of one jet relative to the other.

If this block moves parallel to one of its edges with a speed of 0.80c past an observer, (a) what shape does it appear to have to this observer? (b) What is the length of each side as measured by the observer? Figure P26.14arrow_forward

- Observations of neutrinos emitted by the supernova SN1987a place an upper limit of 20 eV on the rest energy of the electron neutrino. If the rest energy of the electron neutrino were, in fact, 20 eV, what would be the speed difference between light and a 1.5 MeV electron neutrino?arrow_forward. Many galaxies have supermassive black holes at their centers. As material swirls around such a black hole, it is heated, becomes ionized, and generates strong magnetic fields. The resulting magnetic forces steer some of the material into high-speed jets that blast out of the galaxy and into intergalactic space. The light we observe from the jet in Fig. has a frequency of 6.66x10^14 Hz (in the far ultraviolet region of the electromagnetic spectrum), but in the reference frame of the jet material, the light has a frequency of 5.55x10^13 Hz (in the infrared). What is the speed of the jet material with respect to us?arrow_forwardWhat will be the mean lifetime of a muon as measured in the laboratory if it is traveling at v=0.1c with respect to the laboratory?
