Answer: The answer for me was The Current Doubles as Well
Explanation:
Answer: Availability of water
Explanation:
When a person is travelling from a forest ecosystem towards grassland ecosystem the number of trees gets reduced in number.
The trees are replaced by prairie grasses. This change is because of less water availability in the area having grass.
The amount of precipitation decides the type of vegetation found in that area.So the area having trees would be having more precipitation as compared to the area having prairie grass.
The <span>energy of the photon emitted when the electron in a hydrogen atom drops from energy level E5 to energy level E2 is 2.85eV
Now, the energy of the ground state is -13.6 eV.
</span>the energy of the first state (n = 1) is -3.39 eV.
the energy of the fifth state is -0.54 eV.
Now, When an electron drops from higher to lower state, then energy difference is same as the energy of the photon emitted, is
= E5 - E2
= -0.54 eV -(-3.39 eV)
= 2.85 eV
