I think its D answer
sorry I dont have explanation but I think its D
Answer:
Variable independiente
Explanation:
una variable independiente. Es una variable que está sola y no es modificada por las medidas de otras variables
Pressure is defined as force per area.
It is normally further advantageous to apply pressure preferably than force to explain the importance toward liquid reaction.
Answer:
The answer is explained below.
Explanation:
The energy emitted during the de-excitation of an electron from a higher energy level to a lower energy level is directly proportional to the frequency of the emitted light.
Here, the total sum of the energies of 2 frequencies of light emitted in different stages is equal to the energy of a single frequency of light during the de-excitation of fourth level to ground level directly.
Hence the total sum of of the frequencies of 2 lights emitted in different stages is equal to the frequency of single frequency of light emitted during the de-excitation from fourth level to ground level directly.
The some of the energies of 2 frequencies emitted by one electron is equal to the energy of a single frequency when electron jumps directly.
