Qhov yooj yim tsev blocks uas ua teeb meem hu ua atoms. Dab tsi yog qhov sib txawv particles pom hauv atoms? (Cov lus teb: electrons, protons thiab neutrons) Lawv pom qhov twg? (Lus teb: Protons thiab neutrons pom nyob rau hauv lub nucleus, thiab electrons muaj nyob rau hauv lub plhaub nyob ib ncig ntawm lub nucleus.)
Kuj tseem yuav paub yog, dab tsi yog qhov yooj yim lub tsev thaiv ntawm teeb meem?
atom
Qhov thib ob, dab tsi yog lub tsev blocks ntawm teeb meem sawv cev los ntawm lub cim? Ua ntej cia peb saib cov ntawv: CO. Atoms muaj cov cim tshuaj lom neeg; txhua keeb tau muab ib lossis ob tsab ntawv los sawv cev rau nws. Yog li, C stands rau carbon , thiab O sawv rau oxygen (tag nrho cov cim tshuaj no tuaj yeem pom hauv daim ntawv teev sijhawm hauv daim duab 2 hauv qab no).
Tom qab ntawd, vim li cas atoms hu ua lub tsev thaiv cov teeb meem?
Atoms yog qhov yooj yim tsev blocks ntawm dog dig teeb meem . Atoms tuaj yeem koom ua ke los tsim cov molecules, uas ua rau feem ntau ntawm cov khoom nyob ib puag ncig koj. Atoms yog tsim los ntawm particle hu ua protons, electrons thiab neutrons.
Dab tsi yog lub tsev thaiv ntawm txhua qhov teeb meem quizlet?
Atoms yog cov khoom me me teeb meem . Piv txwv li, cov pa oxygen molecule yog tsim los ntawm ob lub pa oxygen atoms uas koom ua ke. Basic lub tsev thaiv rau txhua qhov teeb meem nyob hauv lub qab ntuj khwb. Nws yuav siv ntau lub atoms los ua ib yam dab tsi, piv txwv li muaj trillions thiab trillions ntawm atoms uas ua rau tib neeg lub cev.

Dab tsi yog qhov txawv ntawm qhov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem nyob rau hauv daim ntawv ntawm cov tsis muaj sia nyob cov as-ham tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov ua dua tshiab hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov txawv ntawm qhov ntws ntawm cov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem hauv daim ntawv ntawm cov khoom noj uas tsis muaj sia nyob uas tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov siv dua hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov txawv ntawm wavelength ntawm lub teeb liab thiab lub teeb violet?
Violet lub teeb yog hluav taws xob hluav taws xob hluav taws xob nrog wavelengths ntawm 410 nanometers thiab lub teeb liab muaj awavelength ntawm 680 nanometers. Qhov ntau ntawm wavelengths (400 - 700 nm) ntawm lub teeb pom kev yog nyob nruab nrab ntawm lub electromagnetic spectrum (Fig.1)
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
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
