A tsev yog a composite daim duab nrog nws cov duab plaub thiab squares. Lwm lub ntiaj teb tiag piv txwv yog ib lub tshuab cua uas muaj ib daim duab peb sab thiab ib daim duab plaub. Lub tsheb uas muaj cov duab plaub yog ib kev sib xyaw ua ke . Thaum kawg muaj ntau lub koom txoos muaj Composite cov duab hauv lawv tsim.
Ib yam li ntawd, tib neeg nug, puas yog daim duab sib xyaw?
Composite Figures . A daim duab (los yog cov duab) uas tuaj yeem muab faib ua ntau tshaj ib qho ntawm qhov pib cov duab hais tias yog ib composite daim duab (los yog puab). Piv txwv li, daim duab ABCD is a composite daim duab raws li nws muaj ob qho yooj yim cov duab . Ntawd yog, a daim duab yog tsim los ntawm ib daim duab plaub thiab daim duab peb sab raws li qhia hauv qab no.
Ib yam li ntawd, puas yog ib qho trapezoid ib daim duab sib xyaw? Nyob rau hauv ntau zaus, geometric daim duab yog tsim los ntawm ntau yam sib txawv cov duab , xws li daim duab peb sab, quadrilaterals, voj voog, thiab lwm yam. Xws li ib daim duab npe a composite daim duab . Cov daim duab yog ib tug trapezoid , tab sis xav txog lub sijhawm uas koj tsis nco qab cov qauv rau thaj tsam ntawm a trapezoid.
Tsuas yog li ntawd, ib daim duab plaub puas yog daim duab sib xyaw?
A composite daim duab yog tsim los ntawm ntau yam geometric yooj yim cov duab xws li daim duab peb sab, duab plaub , squares, voj voog, thiab semicircles. Mus nrhiav thaj tsam ntawm a composite daim duab , cais cov daim duab rau hauv cov duab yooj yim uas nws cheeb tsam tuaj yeem pom.
Yuav ua li cas koj thiaj paub yog tias ib tug duab yog prism?
Yog tus puab muaj qhov siab thiab dav, ces nws xav tau qhov tob thiab ua ib prism . A prism kuj muaj ob kawg, txhua lub ntsej muag, raws nraim tib yam, uas feem ntau muab nws lub npe. Piv txwv li, ib daim duab peb sab prism muaj ob daim duab peb sab zoo tib yam. Yog tag nrho cov sab yog rectangular, ces nws yog hu ua rectangular prism.

Ib qho piv txwv ntawm zej zog ecology yog dab tsi?
Zej Zog Ecology Piv Txwv Zej Zog ecology encompasses ntau hom kev sib cuam tshuam ecological uas txuas ntxiv hloov mus rau lub sijhawm. Lub zej zog hav zoov suav nrog cov zej zog cog, txhua tsob ntoo, noog, squirrels, mos lwj, hma, fungi, ntses hauv hav zoov, kab thiab tag nrho lwm hom tsiaj nyob ntawd lossis tsiv teb tsaws raws caij nyoog
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Puas yog Krypton yog ib qho khoom sib xyaw lossis sib xyaw?
Krypton (Kr), cov khoom siv tshuaj, cov pa roj tsawg ntawm Pawg 18 (noble gases) ntawm lub sij hawm lub sij hawm, uas tsim cov tshuaj muaj pes tsawg leeg. Txog peb zaug hnyav dua huab cua, krypton tsis muaj xim, tsis muaj ntxhiab, tsis qab, thiab monatomic
Puas yog hlau yog ib qho khoom sib xyaw lossis sib xyaw?
Hlau yog ib yam khoom thiab tsis yog ib qho kev sib xyaw los yog sib xyaw ua ke lossis kev daws teeb meem. Ib lub caij yog tus cwj pwm los ntawm cov atoms ntawm tib yam khoom, uas yog, lub ntsiab yog tsim los ntawm tib lub atoms. Hlau yog tsim los ntawm hlau atoms
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
