Piv txwv li, Planck qhov tsis tu ncua tuaj yeem sau ua h=6.6x10-34 joule vib nas this. Siv Planck qhov tsis tu ncua, Bohr tau txais cov qauv tseeb rau qib zog ntawm hydrogen atom. Nws postulated tias lub angular momentum ntawm lub electron yog quantized - piv txwv li, nws muaj peev xwm tsuas muaj discrete qhov tseem ceeb.
Leej twg hais tias lub atom yog quantized?
Bohr yog thawj tus paub qhov no los ntawm kev sib koom ua ke lub tswv yim ntawm quantization rau hauv cov qauv hluav taws xob ntawm hydrogen atom, thiab nws muaj peev xwm piav qhia qhov emission spectra ntawm hydrogen li. zoo li lwm lub tshuab hluav taws xob.
Vim li cas angular momentum ntawm electron yog quantized?
Raws li Bohr tus qauv atomic, lub angular momentum ntawm electrons orbiting ncig lub nucleus yog quantized. Nws hais ntxiv tias electrons txav tsuas yog nyob rau hauv cov orbits qhov twg lub angular momentum ntawm ib tug electron yog ib tug ntau yam ntawm h/2.
Lub ntsiab lus ntawm lub zog ntawm lub zog ntawm lub zog hluav taws xob yog dab tsi?
Quantization ntawm angular momentum txhais tau hais tias lub vojvoog ntawm lub orbit thiab lub zog yuav raug suav nrog Bohr xav tias cov kab sib cais pom hauv spectrum ntawm hydrogen atom yog vim rau kev hloov ntawm ib qho hluav taws xob los ntawm ib qho kev tso cai orbit / lub zog mus rau lwm qhov.
Neil Bohr atomic qauv yog dab tsi?
Atomic qauv
Bohr qauv qhia lub atom raws li ib tug me me, zoo nqi nucleus ncig los ntawm orbiting electronsBohr yog thawj zaug nrhiav pom tias electrons mus txawv tebchaws. orbits nyob ib ncig ntawm lub nucleus thiab hais tias tus naj npawb ntawm electrons nyob rau hauv lub orbit txheej txiav txim lub zog ntawm ib lub caij.

Nyob hauv lub tswb hluav taws xob lub tshuab hluav taws xob yog sib nqus thaum hloov pauv?
Thaum qhov hloov pauv (K) raug kaw, qhov hluav taws xob tam sim no dhau los ntawm lub roj teeb (U) los ntawm cov cua tshuab hluav taws xob. Nws tsim magnetic teb uas nyiam lub caj npab hlau ntawm tus npuaj teg, rub nws los muab lub tswb rau tus kais .
Yuav tsum tau hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob?
Kuv puas yuav tsum hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob? Ignition coils thiab spark plugs ua haujlwm zoo ua ke. … Tab sis yog tias koj tsuas yog hloov koj lub qhov hluav taws xob ua ib feem ntawm kev saib xyuas niaj hnub, nws tsis tsim nyog los hloov koj cov hluav taws xob hluav taws xob tib lub sijhawm tshwj tsis yog muaj cov cim qhia tias lawv ua tsis tau Yuav tsum hloov cov hluav taws xob hluav taws xob ntau npaum li cas?
Puas yog roj hluav taws xob hluav taws xob hluav taws xob zoo?
Central gas heating systems siv natural gas rau tsev sov. Kuv xav siv cov pa roj carbon monoxide tsis zoo rau lub hauv nruab nrab cua sov vim tias nws yooj yim, yooj yim, txhim khu kev qha, thiab ua haujlwm zoo dua. Thaum tshav kub kub uas los ntawm cov nkev ntuj pom tau tias sov dua li cua sov tawm ntawm lub hauv paus system .
Lub tshuab hluav taws xob twg yog qhov zoo tshaj plaws rau lub tshuab hluav taws xob?
Lub DC lub cev muaj zog yog qhov zoo tshaj plaws rau lub tshuab hluav taws xob. Nws yuav tsim tam sim no, txawm tias qhov ceev ntawm kev sib hloov yog me ntsis tsawg. Thaum koj siv ib theem lub cev muaj zog, koj yuav tsum tig nws ntawm qhov nrawm dua li cov motors synchronous ceev kom tsim tau lub zog .
Thaum twg ib qho hluav taws xob thiab ib qho hluav taws xob sib tsoo lawv?
Thaum ib qho hluav taws xob thiab positron (antielectron) sib tsoo ntawm lub zog siab, lawv tuaj yeem rhuav tshem los tsim cov quarks ntxim nyiam uas tom qab ntawd tsim D + thiab D - mesons . Yuav ua li cas thaum photons sib tsoo?
