Answer:
Up to 80 - 120 days.
Explanation:
The flower will probably stay six to twelve days or so.
I'm not sure what's your hypothesis going to be, but I'll give you an example.
" <em>If</em> I __________, <em>then</em> the sunflower will grow up to 80 to 120 days."
In the blank space, you can write what you're going to do to your sunflower during the experiment.
Please correct me if I'm wrong.
Answer:
The absorption and strength of the H-beta lines change with the temperature of the stellar surface, and because of this, one can find the temperature of the star from their absorption lines and strength. To better comprehend, let us look into the concept of the atom's atomic structure.
Atoms possess distinct energy levels and these levels of energy are constant, that is, the temperature has no influence on it. However, temperature possesses an influence on the electron numbers found within these levels of energy. Therefore, to generate an absorption line of hydrogen in the electromagnetic spectrum's visible band, the electrons are required to be present in the second energy level, that is when it captivates a photon.
Therefore, after captivating the photons the electrons jump from level 2 to level 4, which shows that there is an increase in the stellar surface temperature and at the same time one can witness a decline in the strength of the H-beta lines. In case, if the temperature of the surface increases too much, then one will witness no attachment of electron with the hydrogen atom and thus no H lines, and if the temperature of the surface becomes too low, then the electrons will stay in the ground state and no formation of H lines will take place in that condition too.
Hence, to generate a very robust H line, after captivating photons the majority of the electrons are required to stay in the second energy level.
Answer:
the positive charges of the nuclei and the negative charges of delocalized electrons
Explanation:
The interatomic forces that joins a piece of metal atoms together are the positive charges of the nuclei and the negative charges of delocalized electrons.
This bond type is the metallic bond.
- The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice.
- Also, the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
