A hloov chaw yog a vector nws qhov ntev yog qhov luv tshaj plaws ntawm qhov pib mus rau qhov kawg txoj hauj lwm ntawm apoint P. Nws quantifies ob qhov kev ncua deb thiab kev taw qhia ntawm animaginary motion raws ib txoj kab ncaj nraim los ntawm thawj txoj hauj lwm mus rau qhov kawg txoj hauj lwm ntawm lub point.
Tom qab ntawd, kev hloov pauv hauv cov lus yooj yim yog dab tsi?
Cov kev txav chaw txhais tau hais tias ib yam khoom tau tsiv, los yog tau lawm hloov chaw . Kev khiav tawm txhais tau tias yog qhov kev hloov ntawm txoj hauj lwm ntawm ib yam khoom.
Tsis tas li ntawd, kev hloov pauv yog dab tsi piav qhia nrog piv txwv? Piv txwv li: yog peb xav tib yam piv txwv raws li tau hais ua ntej, tag nrho hloov chaw ntawm cov khoom yuav yog qhov ntev ntawm txoj kab koom nrog ob txoj haujlwm. Cov hloov chaw ntawm ib yam khoom feem ntau luv dua los yog sib npaug rau qhov deb ntawm qhov khoom.
Kuj kom paub, dab tsi yog qhov sib npaug vector?
Sib npaug vectors yog cov duab uas muaj tib qhov loj thiab tib qhov kev taw qhia. Sib npaug vectors tej zaum yuav pib ntawm txoj haujlwm sib txawv. Nco ntsoov tias thaum lub cov duab yog sib npaug , cov directed kab ntu yog parallel. Equality OfColumn Vectors . Yog ob cov duab yog sib npaug tom qab ntawd lawv vector kem yog sib npaug
Dab tsi yog qhov kev txhais zoo tshaj ntawm kev hloov pauv?
Kev khiav tawm (symbolized d lossis s), tseem hu ua qhov ntev lossis qhov nrug, yog ib qho ntawm qhov ntau uas sawv cev rau qhov sib cais ntawm ob txhais cov ntsiab lus. Piv txwv li, peb yuav hais txog qhov kev ncua deb ntawm nruab nrab ntawm lub ntiaj teb thiab anorbiting satellite, thiab ntsuas nws li 13, 000, 000meters.

Kev sib hloov puas tuaj yeem hloov tau los ntawm kev xav?
Ib qho kev txhais lus tuaj yeem hloov tau los ntawm ob qhov kev xav. Ib qho kev txhais lus tuaj yeem hloov tau los ntawm ob qhov kev sib hloov
Koj txhais li cas los ntawm inertia ntawm kev coj?
Inertia ntawm kev taw qhia txhais tau tias yog qhov tsis muaj peev xwm ntawm lub cev lossis khoom siv los hloov nws txoj kev taw qhia ntawm nws tus kheej. Qhov ntawd yog sab nraud quab yuam yuav tsum tau hloov nws txoj kev taw qhia. Qhov no yog vim inertia ntawm kev coj
Koj txhais li cas los ntawm kev them nyiaj ntawm tRNA?
Kev them nyiaj yug tRNA. Ua ntej ib qho amino acid tuaj yeem muab tso rau hauv ib qho kev loj hlob ntawm polypeptide, nws yuav tsum xub muab txuas mus rau lub molecule hu ua hloov RNA, los yog tRNA, nyob rau hauv ib tug txheej txheem hu ua tRNA them. Tus nqi tRNA yuav nqa cov activated amino acid mus rau ribosome
Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
Albert Einstein txoj kev xav ntawm kev sib raug zoo hloov txoj cai ntawm kev txuag hluav taws xob li cas?
Albert Einstein txoj kev xav ntawm kev txheeb ze hloov txoj cai ntawm kev txuag hluav taws xob li cas? Thaum ib yam khoom lossis lub cev ua haujlwm rau lwm yam khoom, qee qhov ntawm nws lub zog raug xa mus rau qhov khoom ntawd
