Pz 15 points an inelastic collision is one in which:

kinetic energy before the collision equals kinetic energy after the collision.

kinetic energy after the collision is zero. (incorrect)

kinetic energy before the collision is less than kinetic energy after the collision.

kinetic energy before the collision is greater than kinetic energy after the collision.

kinetic energy before the collision is greater than kinetic energy after the collision.

Explanation:

I belive this is correct

this a false

explanation:

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.
