Elastic muaj peev xwm zog tuaj yeem khaws cia rau hauv cov hlua roj hmab, bungee chords, trampolines, springs, ib tug xub kos rau hauv hneev nti, thiab lwm yam. elastic muaj peev xwm zog khaws cia nyob rau hauv xws li ib tug ntaus ntawv muaj feem xyuam rau tus nqi ntawm stretch ntawm lub cuab yeej - qhov ntau stretch, qhov ntau khaws cia zog.
Hais txog qhov no, dab tsi yog ib co piv txwv ntawm elastic muaj peev xwm zog?
Ntau yam khoom siv tau tsim tshwj xeeb los khaws lub zog muaj peev xwm, piv txwv li:
- Lub caij nplooj ntoos hlav caij nplooj ntoos hlav ntawm lub voj voog.
- Ib tug archer stretched hneev.
- Ib tug bent diving board, ua ntej ib tug divers dhia.
- Cov roj hmab twisted uas ua rau lub dav hlau ua si.
- Ib lub pob bouncy, compressed thaum lub sij hawm nws thaws tawm ntawm phab ntsa cib.
Tom qab ntawd, lo lus nug yog, puas muaj peev xwm elastic lossis kinetic zog? Muaj peev xwm zog yog zog uas yog khaws cia rau hauv ib yam khoom. Piv txwv li, ib tug roj hmab band uas yog stretched muaj elastic muaj peev xwm zog , vim hais tias thaum tso tawm, cov roj hmab band yuav rov qab mus rau nws lub xeev so, hloov lub muaj peev xwm zog rau kinetic zog nyob rau hauv tus txheej txheem.
Tsis tas li ntawd, lub zog elastic zog txhais li cas?
Elastic muaj peev xwm zog yog lub zog muaj peev xwm khaws cia raws li qhov tshwm sim ntawm deformation ntawm ib qho elastic khoom, xws li stretching ntawm lub caij nplooj ntoos hlav. Nws yog sib npaug ntawm txoj haujlwm ua kom ncab lub caij nplooj ntoos hlav, uas nyob ntawm lub caij nplooj ntoos hlav tas li k nrog rau qhov kev ncua deb.
Elastic muaj peev xwm zog ntsuas nyob rau hauv dab tsi?
Zog khaws cia rau hauv lub caij nplooj ntoos hlav Elastic muaj peev xwm zog yog khaws cia rau lub caij nplooj ntoos hlav. elastic muaj peev xwm zog (E e) yog ntsuas hauv joules (J) caij nplooj ntoos hlav tas li (k) yog ntsuas nyob rau hauv newtons ib 'meter' (N / m) extension (e), xa mus rau qhov nce nyob rau hauv ntev, yog ntsuas hauv meters (m)

Yuav ua li cas cov protein nyob sab nraud ntawm tes ua rau muaj xwm txheej tshwm sim hauv lub cell?
Cov protein tuaj yeem dhau los ntawm daim nyias nyias thiab mus rau hauv lub cell, ua rau muaj teeb meem hauv lub cell. b. Ib qho protein nyob sab nraud ntawm tes tuaj yeem khi rau ib qho receptor protein ntawm lub xov tooj ntawm tes, ua rau nws hloov pauv thiab xa cov teeb liab hauv lub cell. Phosphorylation hloov cov duab ntawm cov protein, feem ntau ua rau nws
Yuav ua li cas cov xwm txheej yuav tsum tau induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau?
Hypothesis: Yuav kom induce ib tug tam sim no nyob rau hauv ib lub voj ntawm hlau, tej yam kev mob yuav tsum tau hais tias muaj ib tug magnetic teb. Qhov no yog vim hais tias thaum ib tug conductor txav los ntawm ib tug magnetic teb, ib tug induced tam sim no yog tsim
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Cov xwm txheej twg tshwm sim nyob rau lub ntiaj teb thaum ntxov?
Tau ntau xyoo lawm, cov kws tshawb fawb ntseeg tias huab cua ntawm lub ntiaj teb thaum ntxov tau txo qis heev, txhais tau hais tias cov pa oxygen tsawg heev. Cov xwm txheej tsis zoo li no yuav ua rau muaj huab cua uas tsis muaj methane, carbonmonoxide, hydrogen sulfide, thiab ammonia
Yuav ua li cas oxygen tshwm sim hauv xwm piav qhia txog lub voj voog oxygen hauv qhov xwm txheej?
Piav lub voj voog oxygen hauv qhov xwm txheej. Oxygen muaj nyob rau hauv ob hom sib txawv hauv qhov xwm txheej. Cov ntaub ntawv no tshwm sim raws li cov pa roj carbon monoxide 21% thiab ua ke hauv daim ntawv oxides ntawm hlau thiab nonmetals, nyob rau hauv lub ntiaj teb crust, cua thiab dej. Oxygen rov qab mus rau qhov chaw los ntawm cov txheej txheem hu ua photosynthesis
