| 1.873 g/m² | Cesium | Cs |
| 2.07 g / cc | Sulfur | S |
| 2.26 g / ct | Cov pa roj carbon | C |
| 2.33 g / ct | Silicon | Si |
Tom qab ntawd, lo lus nug yog, qhov ceev ntawm carbon yog dab tsi? Cov yam ntxwv ntawm carbon sib txawv heev. Nws paub zoo tias pob zeb diamond yog pob tshab thiab tsis muaj hluav taws xob thiab cov graphite yog xim dub thiab cov khoom siv hluav taws xob. Lub atomic ceev yog 3,5g cm−3 rau pob zeb diamond, 2.3 g cm−3 rau graphite, thiab kwv yees li 1 g cm−3 rau feem ntau cov polymers.
Ua kom pom qhov no, lub ntsiab lus dab tsi muaj qhov ntom ntawm 1.53 g cm3?

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
Qhov ceev ntawm mercury 13.6 g cm3 nyob rau hauv units ntawm kg m3 yog dab tsi?
Teb yog: qhov ceev ntawm mercury yog 13600kg / m³. 1 g/cm³ yuav muab 1000kilogram/cubic meter
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
