An electron in the n=7 level of the hydrogen atom relaxes to a lower energy level, emitting light of 1005 nm. part a what is the value of n for the level to which the electron relaxed? express your answer as an integer.

final relaxed state is m = 3

Explanation:

As we know that due to transition of electron the wavelength emitted is given as

now we know that

now we have

now by solving above equation for m we will have

m = 3

so the final relaxed state is m = 3

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

true is the correct answer
