Peb cov qauv tam sim no ntawm lub atom tuaj yeem muab faib ua peb qhov chaw - protons , neutron, thiab electrons . Txhua qhov ntawm cov khoom no muaj cov nqi sib txuam, nrog protons nqa tus nqi zoo, electrons muaj tus nqi tsis zoo, thiab neutrons muaj tsis muaj nqi.
Yog li ntawd, dab tsi yog qhov ntawm atom?
Ib atom muaj 3 qhov yooj yim hais tias nws yog tsim los ntawm. Lawv yog protons, neutrons, thiab electrons. Cov protons yog nyob rau hauv lub nucleus atom thiab muaj ib atomic hnyav li ntawm 1 amu ( atomic mass unit). Lawv raug nqi zoo.
Tsis tas li ntawd, dab tsi yog qhov ntawm lub atom thiab lawv npaj li cas? Atoms muaj peb yam yooj yim hais: protons, electrons, thiab neutrons. Lub nucleus (center) ntawm lub atom muaj cov protons (zoo them) thiab cov neutrons (tsis muaj nqi). Atoms muaj cov khoom sib txawv raws li cov kev npaj thiab tus naj npawb ntawm lawv cov ntsiab lus.
Hais txog qhov no, qhov chaw ntawm lub atom nyob qhov twg?
Cov hluav taws xob yog qhov tsawg tshaj plaws ntawm peb qhov uas ua rau atoms . Electrons muaj nyob rau hauv lub plhaub los yog orbitals uas nyob ib ncig ntawm lub nucleus ntawm ib tug atom . Protons thiab neutrons muaj nyob rau hauv lub nucleus. Lawv koom ua ke nyob rau hauv nruab nrab ntawm lub atom.
Tus qauv ntawm lub atom yog dab tsi?
Piav: Qhov yooj yim qauv ntawm lub atom suav nrog ib tug me me, kuj loj nucleus, muaj tsawg kawg yog ib tug proton thiab feem ntau yog ib los yog ntau tshaj neutrons. Sab nraud ntawm lub nucleus yog qib zog (tseem hu ua plhaub), uas muaj ib lossis ntau dua electrons. Cov electrons yuav luag tsis muaj huab hwm coj thiab raug them tsis zoo.

Dab tsi yog qhov txawv ntawm ib qho ultramafic ib qho mafic nruab nrab thiab felsic pob zeb?
Hauv cov txheej txheem kev faib tawm silica-cov ntsiab lus dav dav, pob zeb nrog ntau dua 65 feem pua silica hu ua felsic; cov uas muaj li ntawm 55 thiab 65 feem pua silica yog nruab nrab; cov uas muaj li ntawm 45 thiab 55 feem pua silica yog mafic; thiab cov uas tsawg dua 45 feem pua yog ultramafic
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
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 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
