Lub hom phiaj : Cov lub hom phiaj ntawm no lab yog los soj ntsuam kev sib raug zoo ntawm qhov ceev ntawm ib yam khoom nyob rau hauv uniform ncig motion (UCM) thiab cov lub zog centripetal ntawm qhov khoom.
Hauv qhov no, lub hom phiaj ntawm lub zog centripetal yog dab tsi?
A lub zog centripetal (los ntawm Latin centrum, "center" thiab petere, "mus nrhiav") yog a zog uas ua rau lub cev ua raws txoj kev nkhaus. Nws cov kev taw qhia yog ib txwm orthogonal mus rau lub zog ntawm lub cev thiab mus rau lub taag point ntawm lub instantaneous centre ntawm curvature ntawm txoj kev.
Ib tug kuj yuav nug, vim li cas lub caij nplooj ntoos hlav ncab hauv koj qhov kev sim thaum cov khoom txav mus rau hauv txoj kev ncig? Yeej qhov khoom txav hauv ncig ncig vim cov caij nplooj ntoos hlav yog lub zog ntawm lub khoom mus rau qhov chaw ntawm lub ncig txoj kev . Muaj kev sib cav sib ceg ntawm qhov no zog og cov khoom inertia.
Ua raws li qhov no, puas yog lub zog centripetal proportional rau huab hwm coj?
Nws nce, vim cov lub zog centripetal yog ncaj qha proportional mus rau pawg ntawm lub cev rotating. Nws nce, vim cov lub zog centripetal yog inversely proportional mus rau pawg ntawm lub cev rotating. Nws txo qis, vim qhov lub zog centripetal yog ncaj qha proportional mus rau pawg ntawm lub cev rotating.
Vim li cas centripetal quab yuam sib npaug qhov hnyav?
Yog tag nrho zog ua haujlwm ntawm lub cev yog C thiab W ( centripetal thiab hnyav ) thiab lub cev ntawd yog tsis txav ( kev ceev a = 0), f = ma = 0 = C + W; ces C = -W, the lub zog centripetal yuav tsum yog sib npaug thiab opposite rau lub hnyav . Thiab yog vim li cas lub zog centripetal thiab hnyav yog " sib npaug "hauv koj li cas.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Lub hom phiaj ntawm pGLO bacterial transformation lab yog dab tsi?
Kev hloov pauv ntawm cov hlwb yog cov cuab yeej siv dav thiab ntau yam hauv kev tsim cov noob caj noob ces thiab yog qhov tseem ceeb hauv kev txhim kho molecular biology. Lub hom phiaj ntawm cov txheej txheem no yog ua kom paub cov plasmid txawv teb chaws rau hauv cov kab mob, cov kab mob ces ua kom cov plasmid, ua kom muaj ntau ntawm nws
Lub hom phiaj ntawm Diels Alder tshuaj tiv thaiv lab yog dab tsi?
Lub hom phiaj ntawm qhov chaw sim no yog los qhia txog lub tswv yim ntawm lub ntsiab lus melting ntawm cov organic compound ua thawj kauj ruam hauv kev txheeb xyuas cov tshuaj lom neeg ntawm qhov sib xyaw thiab tshuaj xyuas nws cov purity. Tsis tas li ntawd, koj yuav ua kom lub voj voog sib txuas los ntawm kev siv lub npe nrov Diels-Alder Reaction
Hom phiaj phiaj xwm phiaj xwm yog Mercator daim ntawv qhia?
Mercator projection. Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. Nws yog feem ntau piav raws li ib tug cylindrical projection, tab sis nws yuav tsum tau muab los ntawm lej
Lub hom phiaj ntawm hydrate lab yog dab tsi?
Lub hom phiaj ntawm qhov chaw kuaj mob no yog txhawm rau txiav txim siab kev sib raug zoo ntawm moles ntawm tooj liab sulfate thiab moles ntawm dej hauv hydrate. Tom qab ntawd siv cov ntaub ntawv no los sau cov qauv ntawm hydrate
