A deuteron consists of one proton and one neutron. A deuteron moving horizontally enters a uniform, verticle magnetic field of 0.500 T. It then travels in a circular arc radius 55.6 cm. How fast was the deuteron moving just before it entered the field? Let the mass of the deuteron m=3.34*10^-27 kg and the charge on a proton q=1.60*10^-19 C.
7.52*10^6 m/s
3.34*10^7 m/s
9.94*10^7 m/s
1.33*10^7 m/s

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
