Calculate the change in internal energy δu of the gas as it expands isothermally from v0 to the final volume fvv0. here, fv is the ratio of final volume to initial volume; fv=4.0 in this problem. express your answer in terms of given quantities.

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:

answer: electrons

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
