Quick Quiz 29. 10 a 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 (c) c, b, a Ch. 29 (b) b, c, a (d) All their speeds are equal. 17
Quick Quiz 29. 10 b 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. Ch. 29 18

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? Ch. 29 21
