Ib electroscope yog ib qho cuab yeej uas kuaj xyuas cov hluav taws xob zoo li qub los ntawm kev siv cov hlau nyias lossis cov nplooj yas, uas cais thaum raug them . Hluav taws xob nqi txav mus rau lub metaland nqes mus rau cov ntawv ci nplooj, uas ces sib ntaus sib tua. Sinceeach nplooj muaj tib yam nqi (zoo lossis tsis zoo), lawv sib cav sib ceg.
Raws li txoj cai, koj puas tuaj yeem qhia tau yog tias ib qho khoom muaj qhov zoo lossis tsis zoo nrog lub Electroscope?
Yog koj nqa a yam tsis zoo nyob ze ntawm electroscope , cov electrons nyob rau hauv lub Scope yuav berepelled rau nplooj, sib npaug ntawm nqi . Yog koj nqa a yam khoom zoo nyob ze ntawm electroscope , nws yuav nyiam cov electrons mus rau lub davhlau ya nyob twg. Nplooj yuav txav deb ntawm ib leeg.
Ib sab saum toj no, koj tuaj yeem siv lub pob pith Electroscope li cas los txiav txim qhov muaj nqi? Qhov no pith - pob electroscope yog siv rau ntes lub xub ntiag ntawm ib qho hluav taws xob static nqi . Ob lub teeb pith ” pob tshem tawm los ntawm cov hlua yog attracted rau cov khoom nrog ib tug staticelectric nqi . Cov pith pob tuaj yeem yog raug them los ntawm kev kov lawv rau ib yam khoom uas muaj hluav taws xob zoo li qub nqi.
Ib yam li ntawd, koj yuav paub li cas yog tias ib qho khoom raug them?
Nyob rau hauv thiaj li yuav qhia sign ib khoom nqi , koj xav tau lwm tus khoom nrog tus paub zoo ornegative nqi . Yog koj rub ib daim iav nrogsilk, nws yuav muaj qhov zoo nqi (los ntawm convention). Yog koj rub ib daig ntawm amber nrog plaub, nws yuav muaj anegative nqi (tseem los ntawm kev sib tham). Siv txhua yam uas koj muaj.
Puas yog Electroscope cuam tshuam tsis zoo?
Yog li ntawd, thaum lub sij hawm tsis zoo - raug them qws isbrought close, the electroscope tau txais txiaj ntsig zoo nqi raws li ib co ntawm nws cov electrons tau khiav mus rau hauv kuv tus ntiv tes. Qhov saum toj kawg nkaus, uas yog nyob ze rau ntawm tsis zoo - raug them rod yog raug them , tab sis qhov qis dua ntawm cov electroscope nyob nruab nrab.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Txhais li cas los ntawm tus nqi ntws ntawm tus nqi hluav taws xob?
Ib coulomb ib ob
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
