Ntawm yog qhia los ntawm lub sijhawm dhau los?
Kev piav qhia: Kev hla dhau yog qhov ntsuas kev hloov pauv ntawm cov khoom hla cov xov xwm dhau lub sijhawm muab. … Qhov kev ntsuas dhau los suav nrog cov neeg siv cov ntaub ntawv thiab lwm yam khoom siv, xws li nyiaj siv ua haujlwm, kev lees paub, thiab kev ntim khoom.
Thaum c-14 nkag mus rau beta lwj kom tsim?
C decays los ntawm tus txheej txheem hu ua beta decay. Thaum lub sijhawm txheej txheem no, ib qho atom ntawm 14 C decays rau hauv an atom ntawm 14 N, thaum twg ntawm cov neutrons nyob rau hauv cov pa roj carbon atom ua ib tug proton. Qhov no nce tus naj npawb ntawm cov protons hauv atom los ntawm ib qho, tsim cov nitrogen atom es tsis yog carbon atom.
