Alpha hluav taws xob yog absorbed los ntawm lub thickness ntawm daim tawv nqaij los yog los ntawm ob peb centimeters ntawm huab cua. Beta hluav taws xob yog nkag tau ntau dua tshaj alpha hluav taws xob. Nws tuaj yeem dhau ntawm daim tawv nqaij, tab sis nws yog absorbed los ntawm ob peb centimeters ntawm lub cev nqaij daim tawv los yog ob peb millimeters ntawm txhuas.
Tsis tas li ntawd, qhov twg muaj lub zog nkag mus tshaj plaws?
Gamma Radiation thiab x-rays yog lub zog hluav taws xob hluav taws xob hluav taws xob (siab zog photons). Qhov kev faib tawm ntawm cov hluav taws xob hluav taws xob no muaj lub zog nkag tau zoo tshaj plaws. Siab zog gamma rays muaj peev xwm hla dhau ob peb centimeters ntawm cov hlau lead thiab tseem raug kuaj pom ntawm lwm sab.
Ib yam li ntawd, cov beta hais puas muaj lub zog nkag siab? Lawv ceev ceev, thiab kaj. Beta particles muaj ib qho nruab nrab nkag mus zog - lawv raug nres los ntawm ib daim ntawv ntawm txhuas lossis yas xws li perspex. Beta hais ionise atoms uas lawv dhau, tab sis tsis muaj zog li alpha particle ua.
Hauv qhov no, qhov twg muaj zog dua alpha beta lossis gamma?
Feem ntau, txawm li cas los xij, alpha hais tias yuav muaj muaj zog ntau dua tshaj lwm tus vim lawv loj heev - ib alpha particle yog zoo ib yam rau lub helium nucleus thiab muaj ob protons thiab ob neutrons, thaum ib tug beta particle yog, qhov tseem ceeb, ib qho hluav taws xob nrawm thiab a gamma ray yog photon nrog xoom
Vim li cas beta particles nkag tau ntau dua li alpha?
Beta hais yog nkag mus ntau dua alpha hais , tab sis tsis tshua muaj kev puas tsuaj rau cov ntaub so ntswg nyob thiab DNA vim hais tias cov ionizations lawv tsim ntau dav dav. Lawv taug kev deb ntawm huab cua tshaj alpha hais , tab sis tuaj yeem nres los ntawm ib txheej ntawm cov khaub ncaws lossis los ntawm ib txheej nyias ntawm cov khoom xws li txhuas.

Qhov twg los thawj qhov ntev lossis qhov dav lossis qhov siab?
Dab tsi los ua ntej? Graphics 'kev lag luam tus qauv yog dav los ntawm qhov siab (dav x qhov siab). Txhais tau hais tias thaum koj sau koj qhov ntsuas, koj sau lawv los ntawm koj qhov kev xav, pib nrog qhov dav. Qhov ntawd tseem ceeb
Qhov twg hnyav dua alpha beta lossis gamma?
Alpha, Beta, Gamma Composition Alpha hais muaj qhov zoo, beta hais muaj qhov tsis zoo, thiab gamma rays yog nruab nrab. Alpha hais muaj ntau dua li beta hais
Qhov twg muaj lub kaum sab xis ntau dua nh3 lossis nf3?
NH3 daim ntawv cog lus lub kaum sab xis yog 107 °. NF3bondangle yog 102 °. Muaj kev cuam tshuam ntau dua rau NH3 vim tias cov ntawv cog lus ib leeg tau noj tsawg dua chav, ze rau cov nitrogen. Fluorine yog ntau electronegative tshaj hydrogen thiab cov electron ceev nyob rau hauv N-F daim ntawv cog lus yog skewed rau fluorine
Qhov twg muaj ntau dua enthalpy 2cl lossis cl2?
Re: Enthalpy Vim tias Cl2 yuav tsum nqus lub zog ntawm ib puag ncig los ua 2Cl, qhov no txhais tau hais tias lub zog ntawm 2Cl yog ntau dua li ntawm Cl2, yog li delta H yog qhov zoo
Cov hauj lwm twg ua tau ntau dua adiabatic lossis isothermal?
Cov kab hauv qab: Qhov loj ntawm kev ua haujlwm rau cov txheej txheem isothermal rau ob qho tib si nthuav thiab compression yog ntau dua qhov loj ntawm kev ua haujlwm rau cov txheej txheem adiabatic. Txawm hais tias kev ua haujlwm ntawm adiabatic compression tsis zoo dua li kev ua haujlwm isothermal compression, qhov kev ua haujlwm tsuas yog nyob ntawm nws qhov loj
