This is a multiple choice with 3 parts so all parts need to be answered. They are not separate questions so this is not against guidelines. Please just give me the number of the questions and the letter of the answer, no need to do too much work. Thank you!!! The bright-line emission spectrum of an element can best be explained by(1) electrons transitioning between discrete energy levels in the atoms of that element.(2) protons being dispersed uniformly throughout the atoms of that element.(3) protons acting as both particles and waves.(4) electrons being located in the nucleus.13)14)White light is passed through a cloud of cool hydrogen gas and then examined with a spectroscope.The dark lines observed on a bright background are caused by(1) the hydrogen emitting all frequencies in white light.(2) the hydrogen absorbing certain frequencies of white light.(3) diffraction of the white light.(4) constructive interference.How much energy is required to move an electron in a mercury atom from the ground state to energylevel h?15)(1) 8.81 eV(2) 1.57 eV(3) 10.38 eV(4) 11.95 eV

The wavelength or frequency of light varies the intensity of light. A spectroscope is a device…

Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inguiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1 N=1 kg · m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb =1 slug ·…
