(a) a proton is confined to the nucleus of an atom. assume the nucleus has diameter 5.5 x 10-15 m and that this distance is the uncertainty in the proton's position. what is the minimum uncertainty in the momentum of the proton? dpmin = kg-m/s
(b) an electron is confined in an atom. assume the atom has diameter 1 x 10-10 m and that this distance is the uncertainty in the electron's position. what is the minimum uncertainty in the momentum of the electron?

Explanation:

h = Planck's constant =

= Uncertainty in the position

= Uncertainty in the momentum

From the uncertainty principle

The minimum uncertainty in the momentum of the proton is

The minimum uncertainty in the momentum of the electron is

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

b.transmitters send radio waves, and receivers capture radio waves.
