Ua raws li qhov no, koj yuav txheeb xyuas qhov kev txiav txim thiab kev tawm tsam li cas?

Qhov loj ntawm lub zog ntawm thawj yam khoom sib npaug ntawm qhov loj ntawm qhov zog ntawm qhov khoom thib ob. Kev taw qhia ntawm lub zog ntawm thawj cov khoom yog opposite rau cov kev taw qhia ntawm lub zog ntawm qhov khoom thib ob. Kev quab yuam ib txwm tuaj ua khub uas sib npaug thiab sib npaug. Cov no yog hu ua kev ua - tshuaj tiv thaiv quab yuam khub.

Tsis tas li ntawd, qhov piv txwv ntawm kev ua thiab kev tawm tsam yog dab tsi? Cov kev txiav txim thiab cov tshuaj tiv thaiv lub zog yog reciprocal (tawm tsam) ntawm ib qho khoom.
