QUESTION 13 22 22-10 Marks) A silver target is bombarded with electrons that have been accelerated by a 35 kilovolt (kV) For silver, the energy difference between the K and L shells is 22 kilo-electronvolt (keV), the energy difference berween the K and M shells is 25 keV. voltage. If the final kinetic energy of a scattered bombarding electron is 30 keV, what is the total energy (in keV) of the x-rays produced? (a) If the wavelength of the x...

The figure below shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to-mass ratio e/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference ΔV, 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....

27B -- Experiment: Magnetic Force on a Moving Charge - qolme Objective: In this module you will observe the trajectory of an electron beam in a uniform magnetic field oriented in various ways to the electron velocity. You will then use your observation of the radius of the electron trajectory to measure the charge to mass ratio for an electron. Equipment: One elm apparatus (Lurge mounted glass bulb with Helmholtz coils); one Leybold or PASCO power supply for electron gun...

To five significant figures, what accelerating potential difference AV is required to detect the ion 0 ? 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. Use the following constants: 1 u = 1.6605 x 10-27 kg, e = 1.6022 x 10-19 C. (Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in...
