Conductors thiab Insulators . Nyob rau hauv ib tug conductor, hluav taws xob tam sim no ua tau ntws ywj siab, hauv ib qho rwb thaiv tsev nws ua tsis tau. "Conductor" implies tias sab nrauv electrons ntawm cov atoms yog loosely khi thiab dawb rau txav los ntawm cov khoom siv. Feem ntau atoms tuav rau lawv electrons nruj thiab yog insulators.
Ua raws li qhov kev pom no, vim li cas thiaj li tsis tuaj yeem electrons txav hauv cov insulators?
Insulators yog cov khoom tsim los ntawm atoms uas tuav rau lawv electrons zog heev. Qhov voltage ntawm ib rwb thaiv tsev yuav tsum tau siab heev ua ntej ib hluav taws xob yog muab lub zog txaus kom dawb nws tus kheej thiab txav los ntawm cov khoom siv. Ntawm insulators , tus nqi ua tsis tau nthuav tawm - yog li koj tau txais txiaj ntsig zoo.
Tsis tas li ntawd, yuav ua li cas electrons txav hauv tus neeg xyuas pib? Thaum ib qho khoom them nqi zoo raug muab tso rau ze ntawm a conductor electrons yog attracted tus kwv. Thaum siv hluav taws xob voltage, ib qho hluav taws xob hauv cov hlau ua rau lub zog ntawm lub electrons , ua rau lawv hloov ntawm ib kawg mus rau lwm qhov kawg tus thawj coj . Hluav taws xob yuav txav mus rau sab zoo.
Tom qab ntawd, ib tus tuaj yeem nug, cov nqi puas tuaj yeem txav mus rau hauv ib qho insulator?
Hauv insulators , zoo li yas thiab roj hmab, electrons tsis pub dawb rau txav ib ncig. Thaum ib rwb thaiv tsev yog raug them , cov nqi nyob qhov twg lawv nyob qhov twg thiab TSIS TAU txav.
Cov electrons txav li cas?
Cov electrons txav los ntawm qhov tsis zoo them nqi mus rau qhov zoo nqi. Cov khoom tsis zoo ntawm txhua lub voj voog muaj ntxiv electrons , thaum cov nqi them zoo xav tau ntau dua electrons . Cov electrons ces dhia ntawm ib cheeb tsam mus rau lwm qhov. Thaum lub electrons txav , tam sim no tuaj yeem ntws los ntawm qhov system.

Yuav ua li cas yog ib tug piv txwv ntawm cov pejxeem nyob rau hauv ib tug ecosystem?
Cov pejxeem yog ib pawg ntawm tib cov kab mob uas nyob hauv ib cheeb tsam. Qee zaum cov neeg sib txawv nyob hauv tib cheeb tsam. Piv txwv li, nyob rau hauv ib lub hav zoov yuav muaj cov pej xeem ntawm owls, nas thiab ntoo thuv. Ntau haiv neeg nyob hauv tib cheeb tsam hu ua ib lub zej zog
Yuav ua li cas cov particles nyob rau hauv ib tug ruaj khov txav?
Cov khoom nyob rau hauv ib qho khoom yog nruj nreem ntim thiab kaw rau hauv qhov chaw. Txawm hais tias peb tsis tuaj yeem pom lossis hnov nws, cov particles txav = vibrating nyob rau hauv qhov chaw. Cov kab hauv cov kua yog nyob ze ua ke (kov) tab sis lawv muaj peev xwm txav tau / swb / ntws dhau ib leeg
Yuav ua li cas yog rau cov ntaub ntawv nug uas yuav tsum tau kawm nyob rau hauv ib tug ua txhaum cai?
Qee yam ntawm cov ntaub ntawv nug uas raug kuaj xyuas cov ntaub ntawv pov thawj tau hais hauv qab no. • Xav. • Tshawb xyuas. • Cov Nyiaj Txiag Nyiaj Txiag. • Daim ntawv cog lus. • Cov ntawv txais nyiaj. • Tub Sab Nraud. • Kev dag ntxias. • Kev cuav. • Kev tua tus kheej. • Kev tua neeg. • Nto nta. • Cov duab latent. • Kev hloov pauv. • Watermarks. • Ink stamps
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Yuav ua li cas koj pom ib tug nyob rau hauv ib tug quadratic muaj nuj nqi?
Qhov kev ua haujlwm quadratic f(x) = a(x -h)2 + k, tsis sib npaug rau xoom, yog hais tias nyob rau hauv cov qauv. Yog tias qhov zoo, daim duab qhib rau sab saud, thiab yog tias qhov tsis zoo, ces nws qhib downward. Txoj kab ntawm symmetry yog txoj kab x = h, thiab vertex yog qhov taw tes (h, k)
