Decay Curve for Radionuclide x Use the following information to answer the next question Questions The sketch below shows a proton travelling in a straight line through uniform perpendicular electric and magnetic fields. The electric field exists between two that are 2.5 cm apart and are maintained at a potential difference of 9. Several gaseous elements and vapours of solid elements are heated. The emitted 275 V. light is studied with a spectroscope. Which statement is correct? The light from each element consists of bright spectral lines that are characteristic of the element. Sample remaining (9% Vapours of solid elements produce spectra that consist of a continuous range proton of wavelengths. source The light from each element consists of a broad and continuous range of wavelengths. 8. If the magnetic field is 2.2 x 10-3 T, the speed of the proton is: Some of the bright lines in the spectrum of an element are exactly the same Time (h) as those in every other element's spectrum. 5.0 x 106 m/s 12.
