Nyob rau hauv lub sci-fi ntug ntawm " Lub hnub qub Trek ", spaceships nrog warp drives tuaj yeem zoom dhau qhov kev txwv tsis pub dhau lub teeb ceev , los yog hais txog 186, 282 mais ib ob (299, 792 kilometers ib ob) hauv lub tshuab nqus tsev.
Ib yam li ntawd, qhov nrawm nrawm npaum li cas piv rau lub teeb nrawm?
Yog li warp 9 sib a ceev ntawm 900 billion kilometers ib teev (= 250 lab kilometers ib ob) los yog txog 830 npaug ntawm ceev ntawm teeb.
Ib yam li ntawd, warp ceev ua haujlwm li cas hauv Star Trek? Warp tsav hauv Lub hnub qub Trek ua haujlwm los ntawm kev rhuav tshem cov teeb meem (nyob rau hauv daim ntawv ntawm deuterium, ib yam ntawm hydrogen gas) thiab antimatter nyob rau hauv ib tug fusion cov tshuaj tiv thaiv mediated los ntawm dilithium muaju. Qhov no ua rau lub zog loj heev uas yuav tsum tau ua warp space-time thiab tsav lub nkoj sai dua lub teeb.
Tom qab ntawd, ib tug kuj yuav nug, cas ceev yog warp 1 nyob rau hauv mph?
Lub spaceship pib tawm ntawm warp 1 thiab nws thiaj li accelerates warp 9.9, los yog li 2,083 lub sijhawm teeb ceev . Warp 1 , lub teeb ceev , ua rau lub tuam txhab zoo li nws nyob ntawm qhov chaw nres tsheb hla lub hnub.
Dab tsi yog lub nkoj ceev tshaj plaws hauv Star Trek?
Cov nkoj ceev tshaj plaws puas tau qhia rau Lub hnub qub Trek yog lub shuttlecraft Cochrane, txuas nrog USS Voyager. Nyob rau hauv ntu ntu, nws ua tiav Warp 10, txhais tau tias nws nyob txhua qhov chaw hauv lub ntiaj teb ib txhij thaum nws tab tom taug kev ntawm qhov nrawm nrawm.

Dab tsi yog kev sib raug zoo ntawm wavelength zaus thiab qhov ceev ntawm lub teeb?
Lub wavelength thiab zaus ntawm lub teeb yog ze ze. Qhov siab dua qhov zaus, qhov luv dua lub wavelength. Vim tias txhua lub teeb tsis txav mus los ntawm lub tshuab nqus tsev ntawm tib lub nrawm, tus naj npawb ntawm nthwv dej crests dhau los ntawm ib qho taw tes hauv ib thib ob nyob ntawm qhov wavelength
Dab tsi yog qhov ceev ntawm huab cua ntawm 10000 ft?
US Standard Atmosphere Air Properties - Imperial (BG) Units Geo-potential Altitude saum hiav txwv theem - h - (ft) Kub - t - (oF) ntom - ρ - (10-4 slugs/ft3) 10000 23.36 17.56 15000 5.55 14.96 20000 -12.26 12.67 25000 -30.05 10.66
Qhov ceev ntawm mercury 13.6 g cm3 nyob rau hauv units ntawm kg m3 yog dab tsi?
Teb yog: qhov ceev ntawm mercury yog 13600kg / m³. 1 g/cm³ yuav muab 1000kilogram/cubic meter
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
