Nws ncaj qha proportional rau lub hauv paus square ntawm qhov ntevthiab inversely proportional rau square cag ntawm acceleration vim lub ntiajteb txawj nqus.
Ntawm dab tsi yog qhov zaus ntawm oscillation ntawm pendulum B nyob ntawm?
Yog li ntuj zaus ntawm qhov thib ob pendulum nyob ntawm lub hauv paus square ntawm qhov hloov pauv ntawm nws qhov ntev.
Tus qauv rau conical pendulum yog dab tsi?
Qhov no hu ua centripetal force. Qhov sib npaug ntawm lub zog centripetal yog Fc=mv 2 /r, qhov twg m yog qhov loj ntawm cov khoom, v yog qhov tangential tshaj tawm, thiab r yog lub vojvoog ntawm txoj kev ncig.
Dab tsi yog qhov nro ntawm lub pendulum conical?
Conical pendulum uas nws bob taug kev hauv lub voj voog kab rov tav ntawm lub vojvoog r. Lub bob muaj huab hwm coj m thiab raug tshem tawm los ntawm txoj hlua ntev L. Lub zog nro ntawm txoj hlua ua rau ntawm tus bob yog tus vector T, thiab bob qhov hnyav yog vector mg.
Ntawm yam dab tsi ua qhov zaus ntawm conical pendulum nyob ntawm?
Nws ncaj qha proportional rau lub hauv paus square ntawm qhov ntevthiab inversely proportional rau square cag ntawm acceleration vim lub ntiajteb txawj nqus.

Cov neeg nyob sab qaum teb tau ua li cas qhia lawv txoj kev cog lus rau Kev Tshaj Tawm? Yuav ua li cas cov colonists qhia lawv txoj kev cog lus rau Kev Tshaj Tawm (thaum kawg)?
Puas yog lub pendulum conical?
A conical pendulum muaj qhov hnyav (lossis bob) tsau rau ntawm qhov kawg ntawm txoj hlua lossis pas nrig raug tshem tawm los ntawm pivot. Nws kev tsim kho zoo ib yam li lub pendulum zoo tib yam; Txawm li cas los xij, es tsis txhob viav vias rov qab mus, lub bob ntawm ib lub pendulum txav ntawm qhov nrawm nrawm hauv lub voj voog nrog txoj hlua (los yog pas nrig) taug qab tawm lub khob hliav qab.
Ntawm dab tsi yog cov neeg feem ntau raws li?
Personas yog cov cim tsis tseeb, uas koj tsim raws li koj qhov kev tshawb fawb hauv xaj kom sawv cev rau cov neeg siv sib txawv uas yuav siv koj cov kev pabcuam, khoom lag luam, chaw, lossis hom khoom zoo sib xws txoj kev. Tsim tus neeg pab tus tsim kom nkag siab cov neeg siv cov kev xav tau, kev paub dhau los, kev coj cwj pwm thiab lub hom phiaj.
Dab tsi ntawm cov kab mob feem ntau fossilized?
Fossilization feem ntau tshwm sim hauv cov kab mob nrog tawv, pob txha hauv lub cev, xws li pob txha, hniav, lossis plhaub. Cov kab mob mos, xws li cov kab mob, tsis tshua muaj fossilized. Qee zaum, txawm li cas los xij, cov nplaum nplaum ntawm tsob ntoo tuaj yeem ua fossilized.
