Yog li thaum cov kws tshaj lij xa cov pob ntawm 30 meters ib ob thiab 1,200 hli ntawm kev quab yuam, tus neeg laus neeg laus nruab nrab xa pob ntawm ib ncig ntawm 25 meters ib ob raws li kev ncaws pob 1,000 phaus ntawm kev quab yuam, thaum nruab nrab cov tub ntxhais hluas ncaws pob tsuas tuaj yeem khaws lub pob nrawm ntawm 14.9 meters ib ob, qhia tsuas yog 600 phaus.
Kuj tseem paub yog, lub zog ntawm ncaws pob yog dab tsi?
Lub zog ntawm lub pob tuaj yeem txiav txim siab los ntawm kev siv lub impulse-momentum daim ntawv ntawm Newton txoj cai thib ob ntawm cov lus tsa suab, uas tuav tau tias lub zog sib npaug ntawm qhov hnyav ntawm lub pob lub sij hawm nws ceev muab faib los ntawm lub sij hawm ntawm ko taw kev sib txuas. Hauv qhov piv txwv ntawm kev ncaws pob txav 30 meters ib ob, lub zog yog 270 Newtons.
Tsis tas li ntawd, lub zog twg yog ncaws pob? Kinetic zog
Tsis tas li lo lus nug yog, ncaws pob ncaws pob yog qhov tsis sib npaug?
Ib yam khoom tuaj yeem txav tau txawm tias lub vas zog ua rau nws yog xoom. A ncaws pob , piv txwv li, tau txais ib qho tsis sib npaug zog thaum nws yog ncaws . Txawm li cas los xij, lub pob txuas ntxiv dov raws hauv av ntev tom qab lub zog ntawm ncaws tau tas lawm. Kev sib txhuam yog ib zog uas ua nyob rau hauv ib qho kev taw qhia opposite rau kev txav.
Yuav siv zog li cas hauv kev ncaws pob?
Kev sib txhuam tiv thaiv koj lub pob ncaws pob mus rau pem hauv ntej mus ib txhis thaum nws ncaws. Lub pob ncaws pob rub tawm hauv av, uas ua rau muaj kev tawm tsam thiab ua rau lub pob qeeb. Nws tuaj yeem yog qhov tsis xav tau vim tias nws tuaj yeem tiv thaiv lub pob kom nkag mus rau hauv lub hom phiaj. Lub ntiajteb txawj nqus yog lwm lub zog uas cuam tshuam rau kev ncaws pob.

Nws siv sijhawm ntev npaum li cas rau txhua lub ntiaj teb los tig ntawm nws qhov axis?
Lub ntiaj teb siv sijhawm 24 teev los ua kom tiav ib lub kiv, thiab Mars siv sijhawm 25 teev. Gas giants tig ceev heev. Jupiter tsuas yog siv sijhawm 10 teev los ua kom tiav ib qho kev sib hloov. Saturn siv sijhawm 11 teev, Uranus siv sijhawm 17 teev, thiab Neptune siv sijhawm 16 teev
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Thaum tus ncaws pob ncaws pob lub pob nrawm?
Thaum peb ncaws pob, lub zog peb siv rau nws ua rau nws nrawm nrawm ntawm 0 mus rau qhov ceev ntawm kaum ob kilometers ib teev. Thaum lub pob tso tawm ntawm ko taw, nws pib decelerate (tsis zoo acceleration) vim yog lub zog ntawm kev sib txhuam uas yog exerted rau nws (raws li peb tau pom nyob rau hauv cov piv txwv yav dhau los)
Nws siv zog npaum li cas los rhuav tshem ib daim ntawv cog lus?
Raws li ib qho piv txwv ntawm daim ntawv cog lus dissociation enthalpy, kom tawg 1 mole ntawm gaseous hydrogen chloride molecules rau cais gaseous hydrogen thiab chlorine atoms yuav siv sij hawm 432 kJ. Daim ntawv cog lus dissociation enthalpy rau H-Cl daim ntawv cog lus yog +432 kJ mol-1. bond enthalpy (kJ mol-1) C-Cl + 346 H-Cl + 432
Nws siv sijhawm ntev npaum li cas los tsim lub foob pob atomic?
Lub Laboratory tau tsim nyob rau hauv 1943 raws li qhov chaw Y ntawm Manhattan Project rau ib lub hom phiaj: tsim thiab tsim lub foob pob atomic. Nws tsuas siv 27 lub hlis xwb. Thaum Lub Xya Hli 16, 1945, lub ntiaj teb thawj lub foob pob tawg tau tawg 200 mais sab qab teb ntawm Los Alamos ntawm Trinity Site ntawm Alamogordo Bombing Range
