  10. Exotic astrophysical phenomena may be addressed with future multi-Petawatt lasers HEDP Task Force The minimal requirements for photon-bubble instability could potentially be met with a properly configured 10 ps PetaWatt laser experiment. Neutron Star Te ~ 10 keV Trad ~ 10 keV B ~ 10 Gigagauss @ n ~ 10-1-10-3 g/cm3 PetaWatt Laser Te ~ 1 keV Trad ~ 1 keV B ~ 100 Megagauss @ n ~ 10 g/cm3 B ~ 106 T B ~ 104 T

  13. Quick Quiz 29.10a Three types of particles enter a mass spectrometer like the one shown in your book as Figure 29.24. The figure below shows where the particles strike the detector array. Rank the particles that arrive at a, b, and c by speed. (a) a, b, c (b) b, c, a (c) c, b, a (d) All their speeds are equal.

  14. Quick Quiz 29.10b Rank the particles that arrive at a, b, and c by m/q ratio. (a) a, b, c (b) b, c, a (c) c, b, a (d) All their m/q ratios are equal.

  17. Quick Quiz 29.4 The four wires shown below all carry the same current from point A to point B through the same magnetic field. In all four parts of the figure, the points A and B are 10 cm apart. Rank these situations according to the magnitude of the magnetic force exerted on the wires, from greatest to least?
