The Lorentz force causes charged particles to orbit around magnetic field lines. At what rate do protons orbit around a field line? Assume the protons have energy of 1 MeV and are in a magnetic field with strength B = 2.4×10-7 T. Find the orbital frequency in revolutions/second (Hz); express your answer to 3 significant digits. The protons orbit the field at _____ Hz.
How would the answer to the previous problem change if the particles were 1 MeV electrons, instead of protons?

- In the Check Your Learning section of Example 27.1, you were told that several lines of hydrogen absorption in the visible spectrum have rest wavelengths of 410 nm, 434 nm, 486 nm, and 656 nm. In a spectrum of a distant galaxy, these same lines are observed to have wavelengths of 492 nm, 521 nm, 583 nm, and 787 nm, respectively. The example demonstrated that z=0.20 for the 410 nm line. Show that you will obtain the same redshift regardless of which absorption line you measure.arrow_forwardConsider a US Air Force launch of its latest GPS satellite from Cape Canaveral.

Thanks!arrow_forwardWe receive today the light from a distant galaxy and from its spectrum we conclude that it took 400 Myr for the photons to reach us. Which one of the following statements is correct? O The Universe is accelerating, so that galaxy is moving toward us at higher speed and it will take less than 400 Myr for future photons from that galaxy to reach us. O That galaxy is 400 million light years away from us today. O That galaxy is moving away from us, so today it is more distant from us than 400 million light years. O We are observing that galaxy as it was in the past, and today it is accelerating toward us.arrow_forward
