I-green chemistry, eyaziwa nangokuthi i-sustainable chemistry, iyindlela ye-chemistry egxile ekwakhiweni kwemikhiqizo yamakhemikhali kanye nezinqubo ezinciphisa noma eziqeda ukusetshenziswa kanye nokukhiqizwa kwezinto eziyingozi. Umgomo oyinhloko we-green chemistry ukudala izinqubo ezinobungani nemvelo, ezisebenza kahle, neziqhubekayo. Lezi zimiso zibalulekile ekusekeleni imizamo yokonga... Funda kabanzi
Isingeniso: I-green chemistry, eyaziwa nangokuthi i-chemistry enobungani nemvelo, insimu ekhulayo ye-chemistry egxile ekwakheni imikhiqizo yamakhemikhali nezinqubo ezinciphisa noma eziqeda ukusetshenziswa kanye nokukhiqizwa kwezinto eziyingozi. I-green chemistry ihlose ukuvimbela ukungcola emthonjeni wayo nokudala ezinye izindlela eziphephile zabantu kanye nemvelo. Lesi sihloko sizoxoxa ngencazelo... Funda kabanzi
Ama-virus ayizinto ezincane kakhulu ezithelelanayo ezingazalana kuphela ngaphakathi kwamaseli aphilayo. Angabangela izifo ezahlukahlukene kubantu, ezilwaneni nasezitshalweni. Ama-virus angasakazeka ngezindlela ezahlukene, okuhlanganisa ukuthintana ngqo, umoya, amanzi, ukudla, kanye nezinambuzane ezifana nezinambuzane. Njengoba kunezingozi ezingaba khona ezibangelwa ukutheleleka ngama-virus, kuvimbela ukusabalala… Funda kabanzi
Ama-virus ayizinto ezincane ezithathelwanayo ezingaphindaphindeka kuphela ngaphakathi kwamaseli aphilayo. Ayaziwa ngokubangela izifo eziningi ezimbi kubantu, ezilwaneni nasezitshalweni. Kodwa-ke, indima yamagciwane idlulela ngale kwalezi zici ezimbi. Ezimweni eziningi, ama-virus adlala indima ebalulekile ezindaweni zemvelo, ocwaningweni lwesayensi, kanye ne-biotechnology. Lesi sihloko… Funda kabanzi
Ama-virus ayizinto ezithelelanayo ezincane kakhulu ezingazalana ngaphakathi kwamaseli aphilayo kuphela. Ukuzalana kwama-virus akugcini nje ngendlela ezinye izinto eziphilayo ezizalana ngayo, kodwa futhi kuncike kakhulu ohlotsheni lwegciwane kanye nomsingathi abamthelela ngalo. Lesi sihloko sizochaza kabanzi ukuthi ama-virus azalana kanjani, sihlanganisa izigaba eziyinhloko zomjikelezo wokuphila kwama-virus, ukuhlukahluka… Funda kabanzi
Ama-virus ayizinto ezithelelanayo ezincane kakhulu ezingazalana ngaphakathi kwamaseli aphilayo kuphela. Angabantu abahlukile, abahlukile kwezinye izinto eziphilayo, ngoba abanaso isakhiwo samaseli noma i-metabolism yabo futhi bathembele ngokuphelele kumnikazi ukuze baphindaphindeke. Ukuqonda ama-virus kuhilela ulwazi ngesakhiwo sawo, izinhlobo, imijikelezo yokuphila, kanye nomthelela ezintweni eziphilayo… Funda kabanzi
Ama-virus ayizinto ezithelelanayo ezincane kakhulu ezingazalana kuphela ngaphakathi kwamaseli ezinto eziphilayo. Ama-virus aqashelwa njengengxenye ebalulekile yesimiso semvelo soMhlaba, enezindima ezahlukahlukene, kusukela kuma-agent abangela izifo kuya kumathuluzi ocwaningo lwesayensi kanye ne-biotechnology. Incazelo kanye Nezimpawu Zamagciwane Ngokwesakhiwo, ama-virus aqukethe i-nucleic acid (i-DNA… Funda kabanzi
Ifomula ye-Angular Momentum Isingeniso I-Angular momentum ingumqondo obalulekile ku-physics ohlobene nokunyakaza kokujikeleza kwento. Ifana ne-linear momentum ekunyakazeni kokuhumusha. I-Angular momentum idlala indima ebalulekile emikhakheni ehlukahlukene ye-physics, kusukela kuma-mechanics akudala kuya kuma-quantum mechanics. Lesi sihloko sizoxoxa ngencazelo ye-angular momentum, amafomula ahlobene nawo, kanye nokusetshenziswa kwawo ku... Funda kabanzi
Ifomula Yokuba Khona Kwamandla Kagesi Isingeniso Amandla kagesi umqondo oyisisekelo kufiziksi kagesi ochaza amandla amandla kagesi ngeyunithi ngayinye yokushaja endaweni ethile ensimini kagesi. Idlala indima ebalulekile ezinhlobonhlobo zezicelo, okuhlanganisa ukwakheka kwezifunda zikagesi, ukuqonda izimo zikagesi nezikazibuthe, kanye nokuhlaziywa kokuziphatha kwezinhlayiya ezishajiwe. Lesi sihloko sizoxoxa ngencazelo yamandla kagesi, amafomula… Funda kabanzi
Ifomula Yokudonsa Amandla adonsela phansi angenye yezinto zemvelo eziyisisekelo nezibaluleke kakhulu ku-physics. Amandla adonsela izinto ezimbili zesisindo esithile komunye nomunye. Umqondo wamandla adonsela phansi waqala ukufundwa ngokujulile nguSir Isaac Newton ngekhulu le-17, futhi kusukela ngaleso sikhathi, ukuqonda kwethu amandla adonsela phansi kuthuthuke ngokushesha ngeminikelo ebalulekile… Funda kabanzi
