are very likely to observe more lines than what you expect from a pure hydrogen gas emission spectrum. Additionally, hydrogen, being the smallest atom, can also leak out the gas tube, weakening the signal. You should look for the expected lines and ignore the lines from contaminants. Element: Hydrogen Color Measured Wavelength (nm) Expected Wavelength (nm) Matching? (Approximately) There are several additional elemental gas tubes set around the room for you to observe. Choose two. Use your handheld spectrometer and...

When rubidium ions are heated to a high temperature, two lines are observed in its line spectrum at wavelengths (a) 7.67 x 10-7 m and (b) 3.99 x 10-7 m. What are the frequencies of the two lines? What color are the lines? Choose the answer that best completes the following: The existence of atomic line spectra indicates that. . . the energy of a photon depends on its frequency. all orbitals in s subshells must be spherical in shape....

Current Designs has two main product lines- composite kayaks, which are handmade and very labor intensive, and rotomolded kayaks, which require less labor but employ more expensive equipment. Current Designs’ controller, Diane Buswell, is now evaluating several different methods of assigning overhead to these products. It is important to ensure that costs are appropriately assigned to the company’s products. At the same time, the system that is used must not be so complex that its costs are greater than its...

choose correct answer. no explanation needed
QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
