Kev sib tsoo, photons, pib ntawm so thiab dhia mus rau ib qho ceev yog tag nrho piv txwv ntawm tej yam lossis cov xwm txheej uas ib tam sim ntawd kev hloov ceev tshwm sim. Photons yog emitted ntawm lub ceev ntawm lub teeb ntsig txog qhov nruab nrab thiab lawv hloov nrawm thaum nkag mus rau lwm qhov nruab nrab.
Ib yam li ntawd, koj tuaj yeem nug, qhov piv txwv ntawm kev nrawm nrawm yog dab tsi?
Nruab nrab Ceev thiab Instantaneous Ceev Thaum lub sij hawm tam sim ntawd peb nyeem los ntawm lub ntsuas ntsuas yog instantaneous ceev . Rau piv txwv , lub tsheb txav mus tas li ceev taug kev mus rau lwm lub nroog, nws yuav tsum nres ntawm lub teeb liab ntawm txoj kev tsheb, lossis nws yuav tsum tau qeeb thaum muaj xwm txheej tsis xav tau tshwm sim hauv txoj kev.
Ib yam li ntawd, qhov ceev ceev tau txais los ntawm lub sijhawm nrawm li cas? Thaum muab ib txoj hauj lwm vs lub sijhawm ua haujlwm , koj yuav tsum kos ib tangent rau lub daim duab ntawm lub sijhawm tam sim thaum koj xav tau nrawm . Nco ntsoov qhov nqes hav ntawm ib txoj hauj lwm vs lub sijhawm ua haujlwm muaj units ntawm nrug muab faib los ntawm sij hawm.
Yog li ntawd, lub ntsiab txhais ntawm instantaneous ceev yog dab tsi?
BSL Physics Glossary - instantaneous ceev - Kev txhais lus txhais : Thaum twg ceev ntawm ib yam khoom yog hloov tas li, lub instantaneous ceev yog cov ceev ntawm ib yam khoom ntawm ib lub sijhawm (instant) hauv lub sijhawm. Piv txwv.
Tus qauv rau kev ceev yog dab tsi?
daws rau ceev los yog siv tus nqi formula rau ceev , s = d/t uas txhais tau tias ceev sib npaug nrug muab faib los ntawm lub sij hawm. Yuav kom daws tau lub sijhawm siv lub qauv rau lub sij hawm, t = d / s uas txhais tau hais tias lub sij hawm sib npaug zos nrug muab faib los ntawm ceev.

Dab tsi yog qhov txawv ntawm qhov nrawm thiab nrawm nrog piv txwv?
Qhov laj thawj yog yooj yim. Kev nrawm yog lub sij hawm tus nqi ntawm qhov khoom txav mus raws txoj kev, thaum lub nrawm yog tus nqi thiab kev taw qhia ntawm qhov khoom txav. Piv txwv li, 50 km / h (31 mph) piav qhia txog qhov ceev ntawm lub tsheb uas taug kev raws txoj kev, thaum 50 km / teev sab hnub poob piav qhia txog qhov nrawm uas nws tab tom taug kev
Qhov zoo li cas yog ib qho piv txwv ntawm qhov zoo ntawm tib neeg?
Qee qhov piv txwv ntawm qhov zoo muaj xws li daim tawv nqaij puag ncig / wrinkled nyob rau hauv peas pods, albinism thiab tib neeg cov ntshav ABO pawg. Cov pab pawg ABO tib neeg cov ntshav qhia txog lub tswv yim no zoo. Tsuas yog qee qhov tshwj xeeb tsis tshua muaj, tib neeg tuaj yeem haum rau hauv ib qho ntawm plaub pawg rau ABO ib feem ntawm lawv cov ntshav: A, B, AB lossis O
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Ib qho piv txwv zoo ntawm kev hloov tshuaj lom neeg yog dab tsi?
Ib qho piv txwv zoo ntawm cov tshuaj hloov pauv.reactants. cov khoom uas tab tom yuav hnov. cov khoom. cov khoom tshiab tsim
Dab tsi yog qee qhov piv txwv ntawm kev cuam tshuam tsis zoo ntawm tib neeg ib puag ncig kev cuam tshuam?
Kev ua liaj ua teb tuaj yeem cuam tshuam tsis zoo rau peb ib puag ncig, suav nrog kev poob ntawm biodiversity, dej paug, kev hloov pauv huab cua, av yaig thiab muaj kuab paug
