The farther away an object is from the Sun the slower it orbits around it. The closer an object is from the Sun the faster it orbits around it.
Answer:
It can be concluded that the star is moving away from the observer.
Explanation:
Spectral lines will be shifted to the blue part of the spectrum if the source of the observed light is moving toward the observer, or to the red part of the spectrum when is moving away from the observer (that is known as the Doppler effect).
The wavelength at rest for this case is 434 nm and 410 nm (
, 
)
Since, 
(444nm) is greater than 
(434 nm) and (420nm) is greater than (410 nm), it can be concluded that the star is moving away from the observer
Answer:
1.Fluorine is having 7 number of electrons and 1 makes bond.
Electronic configuration - 1S² 2S² 2P⁵
1 electron need to get in stable states 2P⁶.
2.Oxygen is having 6 balance electron and 2 makes bonds.
Electronic configuration - 1S² 2S² 2P⁴
2 electron need to get in stable states 2P⁶.
3.Nitrogen is having 5 balance electron and 3 makes bonds.
Electronic configuration - 1S² 2S² 2P³
3 electron need to get in stable states 2P⁶.
4. Carbon having 4 balance electron and 4 makes bonds.
Electronic configuration - 1S² 2S² 2P²
4 electron need to get in stable states 2P⁶.
If everything else is held constant ... the substance from which
the conductor is formed, its cross-sectional area, its temperature
everywhere along its length ... then yes, its resistance will be
directly proportional to its length.
