Protons , neutrons , thiab electrons yog peb lub ntsiab subatomic hais pom nyob rau hauv ib qho atom. Protons muaj tus nqi zoo (+). Ib qho yooj yim kom nco ntsoov qhov no yog kom nco ntsoov tias ob qho tib si proton thiab zoo pib nrog tsab ntawv "P." Neutrons tsis muaj hluav taws xob.
Ib yam li ntawd ib tug yuav nug, dab tsi yog lub npe nqi thiab qhov chaw ntawm peb subatomic hais?
Proton (tus nqi ntawm +e, nyob rau hauv lub nucleus), Neutron (0 nqi, nyob rau hauv lub nucleus), thiab Electron (tus nqi ntawm -e, sab nraum lub nucleus).
Ib tug kuj yuav nug, peb qhov twg yog qhov nruab nrab atoms? Ntawm no, "nruab nrab atom" tsuas yog ib qho atom uas tsis muaj nqi. Saib, ib qho atom muaj protons , neutrons , thiab electrons . Protons raug nqi zoo, electrons raug them tsis zoo (nrog tib qhov loj ntawm tus nqi ntawm ib qho particle li a proton ). Neutrons tsis muaj nqi.
Tsis tas li ntawd, tus nqi ntawm txhua qhov subatomic particle yog dab tsi?
- Subatomic particles yog cov khoom uas me dua lub atom.
- Protons, neutrons, thiab electrons yog peb lub ntsiab subatomic hais pom nyob rau hauv ib lub atom.
- Protons muaj qhov zoo (+) nqi.
- Neutrons tsis muaj hluav taws xob.
- Cov hluav taws xob muaj qhov tsis zoo (-) nqi.
- Protons thiab neutrons yog nucleon.
Dab tsi yog qhov tseem ceeb tshaj plaws hauv lub atom?
Ib hluav taws xob yog ib hom tseem ceeb tshaj plaws ntawm subatomic hais . Hluav taws xob ua ke nrog protons thiab (feem ntau) neutrons ua atoms. Hluav taws xob muaj tsawg dua neutrons thiab protons . Qhov loj ntawm ib leeg neutron los yog proton yog ntau tshaj 1,800 npaug tshaj qhov loj ntawm ib hluav taws xob.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
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
Lub organelle twg ua haujlwm raws li qhov chaw xa ntawv ntawm lub xov tooj ntawm tes txheeb cov proteins thiab xa lawv mus rau lawv qhov chaw xav tau sab hauv lossis sab nraud ntawm tes?
Golgi Hais txog qhov no, dab tsi organelle yog lub luag haujlwm rau kev thauj mus los? endoplasmic reticulum (ER Qhov thib ob, cov proteins txav mus los ntawm lub cell li cas? Cov proteins txav mus los endomembrane system thiab raug xa tawm los ntawm lub ntsej muag trans ntawm Golgi apparatus nyob rau hauv thauj vesicles uas txav mus los cytoplasm thiab tom qab ntawd fuse nrog plasma membrane tso tawm protein ntau mus rau sab nraum lub cell .
Dab tsi yog qhov txawv ntawm qhov ratio ntawm qhov ratio thiab tus nqi?
Ib qho piv txwv piv qhov loj ntawm ob qhov ntau. Thaum qhov ntau muaj qhov sib txawv, ces qhov piv yog hu ua tus nqi. Ib qho piv txwv yog ib nqe lus hais txog kev sib npaug ntawm ob qho piv txwv
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
