Part A (Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio q/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference AV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As the accelerating voltage is slowly increased, different ions reach the detector and are measured. Consider a mass spectrometer with a 200.00 mT magnetic field and an 8.0000 cm spacing To five significant figures, what accelerating potential difference AV is required to detect the ion O, ? The masses of the atoms are shown in the table; the mass of the missing electron is less than 0.001 u and is not relevant at this level of precision.

2) When construction of the Tillery Hydroelectric Plant was begun in 1926, it was realized that the reservoir resulting from the construction of the dam would flood the Swift Island Bridge across the Pee Dee River, and led to the construction of the present Swift Island Bridge. The US Army Air Corp decided to test aerial bombardment against the old bridge using the Keystone LB-5 light bomber. Assume an LB-5 approaches the bridge at a 90° angle to the span at 40 m/, and releases its bomb from an altitude of 1 800 m. Ignoring air resistance and crosswinds, How far from the bridge must the bomb be released to hit the bridge on the centerline? b. How long does it take the bomb to hit the bridge after being released? What is the terminal velocity of the bomb? a. с.
