Fizikisi yeChikoro Chesekondari

Muzvinyorwa zviri pamutemo waCoulomb, simba riri pakati pemagetsi rakadzidzwa. Mukuongorora minda yemagetsi, imwe mhando yemutemo waCoulomb yakakurukurwa, inoratidzwa kuburikidza ne equation F = q E, apo F isimba remagetsi, q isimba remagetsi, uye E isimba remagetsi. Zvinogona kutaurwa kuti mutemo waCoulomb mutemo wefizikisi unotsanangura hukama huripo pakati pemagetsi (q) nemagetsi (E).

Munda wemagetsi chinhu chinogadzirwa nechaji yemagetsi uye chinokanganisa nzvimbo yakatenderedza chaji iyoyo yemagetsi, uko simba remunda wemagetsi rinongonzwikwa nemamwe magetsi. Kana imwe chaji yemagetsi iri mumunda wemagetsi inogadzirwa neimwe chaji yemagetsi, imwe chaji yemagetsi inonzwa simba remagetsi.

Tsanangudzo yemunda wemagetsi, sezvakatsanangurwa munyaya nezveminda yemagetsi, inogona kunzwisiswa mupfungwa, asi inogonawo kufungidzirwa mupfungwa. Kuti ufungidzire munda wemagetsi, mitsetse yemagetsi inoratidzwa. Mitsetse yemagetsi imutsara wakadhirowewa wakatenderedza chaji yemagetsi kuratidza kuvapo kwayo. Nekuti inovavarira kuratidza kuvapo kwemunda wemagetsi, pane hukama pakati pemitsetse iyi nemunda wemagetsi. Nemamwe mashoko, hukuru negwara remunda wemagetsi zvinogona kutsanangurwa kuburikidza nedhayagiramu yemitsetse yemagetsi.

Munyaya yeElectric Field , takurukura tsananguro nefomura yemagetsi inogona kushandiswa kuverenga simba remagetsi rinogadzirwa nechaji imwe chete yemagetsi, machaji akawanda emagetsi kana nekugoverwa kwechaji dzemagetsi. Kuverengwa kwesimba remagetsi rinogadzirwa nechaji yemagetsi kana machaji maviri emagetsi kunogadziriswa zviri nyore uchishandisa fomura yesimba remagetsi. Kana chiri kuverengwa chiri simba remagetsi rinogadzirwa nechaji yemagetsi, kuverenga kwacho kwakaoma kana uchishandisa fomura yesimba remagetsi asi kuri nyore kana uchishandisa mutemo waGauss . Usati wadzidza mutemo waGauss zvakadzama, tanga wanzwisisa flux yemagetsi nekuti pfungwa yeflux yemagetsi inoshandiswa mumutemo waGauss.

Kukurukurirana
Kutamiswa kwekupisa nemwaranzi kutamiswa kwekupisa muchimiro chemafungu emagetsi. Muenzaniso wekutamiswa kwekupisa nemwaranzi kutamiswa kwekupisa kubva kuzuva kuenda kuNyika. Pakati peNyika nezuva pane vacuum kana kuti inenge vacuum, saka kupisa kunobva kuzuva, patembiricha yakakwira, kuenda kupasi, patembiricha yakaderera, hakugone kupfuura nepakati pezvinhu. Chiedza chinobva kuzuva kuenda kuNyika iwaya remagetsi, sezvakaita mamwe mafungu emagetsi akawanda, saka zvinogona kugumiswa kuti kupisa kunofamba kubva kuzuva kuenda kuNyika muchimiro chemafungu emagetsi.

Mienzaniso 8 yekufambiswa kwekupisa nekufambisa

1. Tsanangura uchishandisa mienzaniso, zvinoreva kutamiswa kwekupisa kuburikidza nekufambisa ?
Kukurukurirana
Kutamiswa kwekupisa nekufambisa kupisa ndiko kutamiswa kwekupisa kunoitika kuburikidza nekusangana kwemaatomu/mamorekuru anoumba chinhu. Semuenzaniso, funga nezvesimbi inopisa. Mugumo mumwe wesimbi unobatwa nemurazvo uye mumwe mugumo unobatwa. Kunyangwe mugumo wesimbi inobatwa usingabatani nemurazvo, nekuti kupisa kunotamiswa nesimbi, mugumo wesimbi inobatwa unonzwa kupisa. Kupisa kunotamiswa sei kubva kumugumo mumwe wesimbi kuenda kune mumwe?
Musoro wesimbi unopisa unowana kupisa kwakawedzerwa. Macalorie isimba rinofamba kubva pazvinhu zvine tembiricha yakakwira kuenda kuzvinhu zvine tembiricha yakaderera. Simba rakawedzerwa rinoita kuti maatomu/mamorekuru anoumba iron adedere kure kubva panzvimbo yawo yekuenzana. Paanodedera kure, maatomu/mamorekuru anobonderana nemaatomu/mamorekuru ari pedyo, zvichiita kuti maatomu/mamorekuru adedere kure uye awane simba rakawanda. Maitiro aya anoenderera mberi kusvika kupisa kwasvika pamucheto wesimbi iri kubatwa.

3 Mienzaniso yekufambiswa kwekupisa ne convection

1. Tsanangura uchishandisa mienzaniso, zvinoreva kutamiswa kwekupisa ne convection ?
Kukurukurirana
Kutamiswa kwekupisa kweConvection kutamiswa kwekupisa kunoperekedzwa nekufamba kwezvinhu. Semuenzaniso, funga nezvemvura iri mumudziyo wearuminiyamu iri kupiswa pachitofu. Pakutanga, kupisa kunopfuudzwa nekufambisa uye mwaranzi kubva mumurazvo kuenda kumudziyo wearuminiyamu, uyezve nekufambiswa kwemhepo kubva mumudziyo wearuminiyamu kuenda kumvura.
Kutamiswa kwekupisa kwe convection kunotanga kana mvura iri pedyo nemudziyo wearuminiyamu ikawana kupisa kwakawedzerwa, zvichiwedzera tembiricha yayo uye yozokura. Kuwedzera uku kunoderedza huwandu hwayo, zvichiita kuti mvura iyangarare pamusoro. Mvura iyi inotsiviwa nemvura ine tembiricha yakaderera uye huwandu hwakakwira. Maitiro aya anoenderera mberi, achigadzira convection current mukati memudziyo. Maitiro aya anomira kana mvura yese yasvika pamusoro. suhu zvakafanana kana mvura yafashaira.
Mumwe muenzaniso imhepo. Mhepo imhepo iri kufamba. Mhepo inofamba kuitira kuti kupisa kukwanise kufamba kubva kunzvimbo dzine tembiricha yakakwira kuenda kunzvimbo dzine tembiricha yakaderera.
