Maphunziro Oyambira a Fiziki

Nkhani yokhudza lamulo la Coulomb

Mu nkhani yokhudza mphamvu zamagetsi ndi mitundu ya mphamvu zamagetsi, anafotokoza kuti mphamvu zofanana zimatsutsana pomwe zosiyana ndi mphamvu zimakopana. Mwanjira ina, zinthu zomwe zili ndi mphamvu zabwino zimakopa zinthu zomwe zili ndi mphamvu zoipa, zinthu zomwe zili ndi mphamvu zabwino zimatsutsa zinthu zomwe zili ndi mphamvu zabwino, ndipo zinthu zomwe zili ndi mphamvu zoipa zimatsutsa zinthu zomwe zili ndi mphamvu zoyipa. Chochitikachi chikuwonetsa kukhalapo kwa mphamvu zamagetsi zomwe zimagwira ntchito pazinthu zomwe zili ndi mphamvu zabwino komanso zinthu zomwe zili ndi mphamvu zoipa. Ndi zinthu ziti zomwe zimakhudza mphamvu yamagetsi pakati pa zinthu zamagetsi?

Nkhani yokhudza lamulo losunga ndalama zamagetsi

Zinthu zonse zomwe zili mu chilengedwe imapangidwa ndi maatomu. Maatomu amapangidwa ndi ma protoni, ma neutron, ndi ma elekitironi. Protoni imayendetsedwa ndi magetsi; ma elekitironi ali ndi magetsi oyipa, ma neutroni sayendetsedwa ndi magetsi. Mkati mwa atomu, muli ma elekitironi, ma protoni, ndi ma neutroni. Ngati chiwerengero cha ma elekitironi chili chofanana ndi chiwerengero cha ma protoni, mphamvu yonse yamagetsi pa atomu ndi zero. Maatomu ngati awa ndi opanda mphamvu yamagetsi. Ngati chiwerengero cha ma elekitironi chili choposa chiwerengero cha ma protoni, ndiye kuti atomu imakhala ndi magetsi oyipa. Ngati chiwerengero cha ma elekitironi chili chochepera chiwerengero cha ma protoni, ndiye kuti atomu imakhala ndi magetsi oyipa.

Nkhani yokhudza Mitundu ya zolipiritsa zamagetsi

N’chifukwa chiyani pulasitiki imachotsa pulasitiki koma imakopa galasi? Ngati mupaka pulasitiki pa tsitsi louma ndikubweretsa pulasitikiyo papepala laling’ono, pulasitikiyo imakoka mapepalawo. N’chifukwa chiyani pulasitiki imathanso kukoka mapepala omwe sanapakedwe ndi zinthu zina? Mudzamvetsa ndipo mungathe kufotokoza zifukwa zomwe zimapangitsa kuti galasi, pulasitiki, mapepala kapena zinthu zina zichitike monga momwe taonera pamwambapa mutaphunzira nkhani ya magetsi ndikumvetsa ndemanga zomwe zili pansipa.

Mapulasitiki omwe amapakidwa ndi galasi lokoka tsitsi lopakidwa ndi nsalu. Mapulasitiki ndi galasi ndi okongola, kotero pulasitiki ndi galasi ndi zosiyana zolipiritsa zamagetsiNgati chinthu chikuthamangitsa pulasitiki koma chikukoka galasi, chimakhala ndi mphamvu yofanana ndi mphamvu ya galasi. Mosiyana ndi zimenezi, ngati chinthu chikuthamangitsa galasi koma chikukoka pulasitiki, chimakhala ndi mphamvu yofanana ndi mphamvu ya pulasitiki.

Article about the Electric charge in atoms

Please observe one of the objects that are around you. If you destroy an object, for example, it is a stone, the stone will be divided into smaller pieces. If the part of the stone is destroyed again, the stone pieces will turn into smaller pieces. What if the stone is destroyed again? Of course, the stone is smaller. Can stones be destroyed into smaller to infinite pieces? The reality shows that an object is divided into smaller ones will arrive at a point where the smallest part of the object cannot be divided into smaller ones. The smallest part of an object that cannot be divided is called an atom. So, atoms are the smallest part of every material in the chilengedwe.

Nkhani yokhudza kamera ya zida za Optical

Zigawo za kamera

Kamera yosavuta imakhala ndi lenzi yozungulira, diaphragm, shutter, ndi filimu.

Magalasi ozungulira amagwira ntchito popanga chithunzi chenicheni komanso chozungulira pa filimuyo. Mosiyana ndi lenzi ya diso yomwe ili ndi kutalika kwa focal komwe kumasintha, lenzi ya kamera ili ndi kutalika kwa focal komwe sikungasinthe. Lenzi ya kamera ndi lenzi yozungulira, osati mandala opindika chifukwa chithunzi chopangidwa ndi lenzi yokhotakhota nthawi zonse chimakhala chongoyerekeza. M'malo mwake, chithunzi chopangidwa ndi lenzi yokhotakhota chimakhala chenicheni pamene mtunda wa chinthucho uli waukulu kuposa kutalika kwa focal. Chithunzi chenicheni ndi chithunzi chomwe chilipo chifukwa chithunzichi chikhoza kujambulidwa pa filimu. M'malo mwake, chithunzi chenicheni ndi chithunzi chabodza kotero kuti chithunzicho sichingajambulidwe pa filimu. Malo a chithunzi chenicheni ndi chopotoka chopangidwa ndi lenzi yokhotakhota chimagwirizana ndi malo a filimuyo.

Nkhani yokhudza Equation ya ma telescope a zakuthambo

Ngodya imatsimikizira kukula kwa chithunzi cha chinthu chomwe chapangidwa pa retina. Monga momwe chithunzichi chikusonyezera, mtunda wa chinthucho kuchokera pa diso umakhala wocheperako, motero kukula kwa chithunzi chomwe chapangidwa pa retina kumachepa.

Telesikopu yosavuta ya zakuthambo ili ndi magalasi awiri ozungulira; iliyonse imatchedwa lenzi yolunjika ndi lenzi ya maso. Lenzi yolunjika ili ndi mtunda wautali kuchokera ku diso, pomwe lenzi ya maso ili ndi mtunda pafupi ndi diso. Lenzi yolunjika imagwira ntchito yobweretsa chithunzi pafupi ndi lenzi ya maso, kotero ngodya imakhala yayikulu. Lenzi ya maso imagwira ntchito yowonjezera ngodya kuti kukula kwa chithunzi chomwe chapangidwa pa retina kukhale kwakukulu.

Definition of the astronomical telescope

Astronomical telescopes or astronomical binoculars are the optical instruments used to help the eye see celestial objects such as stars, planets, satellites, etc. Although the size of celestial objects is huge, the distance of celestial objects is so far that when observed using the eyes, celestial bodies appear small. Astronomical telescopes function to enlarge the image of celestial objects so that they can be seen using the eyes.

Nkhani yokhudza Equation ya microscope

Ngodya imatsimikizira kukula kwa chithunzi cha chinthu chopangidwa pa retina ya diso. Monga momwe chithunzi chili m'mbali mwake chikusonyezera, kukula kwa chinthucho kukakhala kochepa, ngodya imatsika ndipo motero kukula kwa chithunzi chopangidwa pa retina kumatsika. Kukula kochepa kwa chithunzi pa retina ndi chifukwa chake diso limavutika kuona zinthu zazing'ono bwino, ngakhale kuti zinthu zimawonedwa kuchokera pafupi, mtunda wa 25 cm.

Tanthauzo la maikulosikopu

Maikulosikopu ndi chinthu chodziwika bwino chida chowunikira imagwiritsidwa ntchito kuthandiza diso kuona zinthu zazing'ono, komwe zinthu zazing'ono zimakhala zovuta kuziona mwachindunji pogwiritsa ntchito maso kapena loupe.

Pali mitundu iwiri ya maikulosikopu, yomwe ndi maikulosikopu yowala ndi maikulosikopu ya elekitironi. Phunziroli likukambirana za maikulosikopu yowala, ndipo momwe imagwirira ntchito pa nkhani ya geometry optics ikuphatikizapo refraction of light, mapangidwe a zithunzi ndi kukula kwa zithunzi za chinthu pogwiritsa ntchito lenzi.

Nkhani yokhudza Equation ya kukula galasi galasi lokulitsa

Monga tafotokozera mu mutu wakuti loupe (galasi lokulitsa), chinthu chimawoneka chaching'ono chikawonedwa patali ndipo chimawoneka bwino chikawonedwa pafupi. Kusiyana kwa kukula kwa chinthu chomwe diso limawona kumachitika chifukwa cha kusiyana kwa ngodya pakati pa diso ndi chinthucho. Chinthu chikakhala kutali kwambiri ndi diso, ngodya pakati pa diso ndi chinthucho imakhala yocheperako kotero kuti chithunzi chopangidwa pa retina ya diso chimakhala chocheperako. Mosiyana ndi zimenezi, chinthucho chikakhala pafupi ndi diso, ngodya pakati pa diso ndi chinthucho imakhala yayikulu kotero kuti chithunzi chopangidwa pa retina ya diso chimakhala chofunikira kwambiri. Pamene diso lili pafupi, ngodya pakati pa diso ndi chinthucho imakhala yayikulu, kotero kuti chithunzi chomwe chimapangidwa pa retina chikukulanso. Dziwani kuti diso la munthu wamba lili ndi mfundo yoyandikira ndi 25 cm kotero kuti mtunda pakati pa diso ndi chinthucho sungakhale wocheperako kuposa 25 cm. Titha kunena kuti ngodya pakati pa diso labwinobwino la munthu wamba ndi chinthu ndi yayikulu kwambiri pamene mtunda pakati pa diso ndi chinthucho ndi 25 cm.
