Different theoretical models or methods can describe the nucleon-nucleon interaction for few- nucleon systems. describe each of the following methods, stating its basics assumptions, why and when it can be used, etc a) effective field / chiral perturbation theory approach; b) faddeev-yakubovsky method. (10) (10) in each case, state at least one advantage and one disadvantage of the method.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

if they have a finite resultant
