Static hluav taws xob yog kev txhim kho ntawm nqi on ib khoom . Thaum ib yam khoom nce lossis poob hluav taws xob, yuav ua li cas ? Thaum ib yam khoom nce lossis poob hluav taws xob , nws yuav dhau los ua postively lossis negatively raug nqi . Koj muaj ob lub balloons.
Hauv qhov no, dab tsi yuav tsum tau nce lossis poob kom dhau los ua hluav taws xob?
Teb: a. Yog li txhua yam kev hloov hauv lub nqi ntawm ib qho atom yog vim muaj kev hloov hauv nws cov electron suav. Yog ib tug nruab nrab atom tau txais electrons, ces nws yuav ua tsis zoo raug nqi . Yog ib tug nruab nrab atom poob electrons, ces nws ua zoo raug nqi . 6.
Tsis tas li ntawd, thaum ib yam khoom tau txais electrons nws ua li cas? Teb: Thaum ib yam khoom poob los yog nce electrons, nws ua (A) hluav taws xob. Kev piav qhia: Thaum muaj hluav taws xob nruab nrab khoom (piv txwv li tsis muaj nqi them) nce electrons , nws txhais tau tias nws muaj ntxiv electrons tam sim no thiab li no ua raug nqi.
Ib yam li ntawd, yuav ua li cas rau tus nqi poob los ntawm ib qho khoom?
Thaum twg electrons raug hloov ntawm khoom , qhov nruab nrab yuav ua raug nqi . Txawm li cas los xij, yog tias atoms poob lossis nce electrons, lawv dhau los raug nqi cov khoom hu ua ions. Koj tuaj yeem pom qhov no li cas tshwm sim nyob rau hauv daim duab hauv qab no. Thaum ib qho atom poob electrons, nws dhau los ua qhov zoo raug nqi ion, los yog cation.
Yuav ua li cas rau ib yam khoom uas muaj nqi zoo?
Yog ib khoom yog qhov zoo raug nqi , nws yuav tawm tsam lwm yam zoo nqi khoom , thiab nws yuav nyiam tsis zoo nqi khoom . Atoms, uas yog lub hauv paus ntawm cov teeb meem, muaj ib tug ntom nucleus ua los ntawm zoo raug nqi protons thiab nruab nrab neutrons. Nyob ib puag ncig lub nucleus yog qhov tsis zoo raug nqi electrons.

Qhov twg hauv qab no yog ib chav tsev rau hluav taws xob hluav taws xob?
Chav tsev rau hluav taws xob lub zog yog joule. Lub zog hluav taws xob rau lub zog yog watt. Cov mis laij lej hluav taws xob ces yog cov qauv hauv qab no. Lub zog hluav taws xob tau nthuav tawm hauv joules, lub zog yog qhia hauv watts, thiab lub sijhawm qhia hauv vib nas this
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog tib yam hauv txhua qhov hluav taws xob hluav taws xob?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
Qhov twg hauv qab no qhia cov piv txwv ntawm tej yam uas hloov hluav taws xob hluav taws xob mus rau thermal zog?
Qhov twg hauv qab no qhia cov piv txwv ntawm tej yam uas hloov hluav taws xob hluav taws xob mus rau thermal zog? Ntxuam thiab cua turbine Toaster thiab chav tso cua sov Lub dav hlau thiab tib neeg lub cev Ntuj lub qhov cub thiab rab
