A mass spectrometer has an adjustable magnetic field. When themagnetic field is 7.000e-2 T, a singly ionizedhydrogen atom (a proton) will strike the detector at a particularlocation. Suppose a triply-ionized carbon 12 atom, whose mass is bydefinition 12 u (where1 u = 1.66×10−27 kg) enters the spectrometer at the same speed as the proton. What is the strength of the magnetic field that will cause it to strike the detector atthe same location as the proton?
An ac voltmeter, which displays the rms voltage between the two points touched by its leads, is used to measure voltages in the circuit shown in the figure . In this circuit, the ac generator has an rms voltage of 7.10V and a frequency of 30.0kHz ..
