Alpha cov khoom muaj zog (ceev) helium nuclei, beta Cov khoom me me thiab muaj ib nrab ntawm tus nqi, ua cov hluav taws xob muaj zog (lossis positrons) tsuas yog gamma particles yog photons, piv txwv li, lawv tsis yog cov khoom loj heev, lawv yog ib hom hluav taws xob hluav taws xob hluav taws xob, ib daim ntawv muaj zog dua li X-rays.
Ntawm no, qhov txawv ntawm alpha beta thiab gamma tawg yog dab tsi?
Qhov sib txawv ntawm Alpha , Beta thiab Gamma Radioactive Decay Alpha decay tsim cov khoom tshiab nrog ob tsawg dua protons thiab ob tsawg dua neutrons; Beta decay tsim cov khoom tshiab nrog ib qho ntxiv proton thiab ib qho tsawg dua neutron. Gamma decay forms TSIS tshiab lub caij, tab sis tam sim no lub caij muaj tsawg zog vim hais tias lub zog tso tawm raws li gamma rays.
Ib yam li ntawd, qhov twg yog qhov txaus ntshai alpha beta lossis gamma? Alpha particle yog cov txaus ntshai tshaj plaws internal hazard as piv nrog gamma rays thiab beta cov khoom. Gamma rays yog cov txaus ntshai tshaj plaws kev puas tsuaj sab nraud. Beta cov khoom tuaj yeem nkag mus rau ntawm daim tawv nqaij, ua rau " beta hlawv". Alpha cov khoom tsis tuaj yeem nkag mus rau ntawm daim tawv nqaij.
Ib yam li ntawd, Alpha Beta thiab Gamma yog dab tsi?
Alpha hluav taws xob yog lub npe rau emission ntawm ib alpha Qhov tseeb yog ib qho helium nuclei, beta hluav taws xob yog qhov emission ntawm electrons los yog positrons, thiab gamma hluav taws xob yog lub sij hawm siv rau emission ntawm lub zog photons.
Dab tsi yog qhov txawv ntawm alpha thiab beta hais?
Alpha hais muaj ntawm ib clump ntawm ob neutrons thiab ob protons. Beta hais yog ib qho electrons (los yog positrons, e +). Alpha hais muaj ntawm ib clump ntawm ob neutrons thiab ob protons. Beta hais yog ib qho electrons (los yog positrons, e +).

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
