Kab rov tav nyob deb tau taug kev ua tau qhia tau tias x = Vx * t, qhov twg t yog lub sijhawm. Ntsug nyob deb los ntawm hauv av tau piav qhia los ntawm cov mis y = h + Vy * t - g * t² / 2, qhov twg g yog lub ntiajteb txawj nqus acceleration.
Ib yam li ntawd, tus qauv ntawm kev hloov pauv yog dab tsi?
Taw qhia rau lub Kev khiav tawm thiab Acceleration Equation Nws nyeem: Kev khiav tawm sib npaug qhov qub tshaj tawm los ntawm lub sij hawm ntxiv rau ib nrab ntawm qhov acceleration multiplied los ntawm lub square ntawm lub sij hawm. Ntawm no yog ib qho piv txwv teeb meem thiab nws txoj kev daws teeb meem uas qhia txog kev siv qhov sib npaug: Ib qho khoom txav nrog qhov nrawm ntawm 5.0 m / s.
koj pom qhov kev ncua deb li cas? Tsuas yog siv cov mis d = √((x2 - x1)2 + (y2 -y1)2). Hauv cov qauv no, koj rho tawm ob lub x coordinates, square qhov tshwm sim, rho tawm y coordinates, square qhov tshwm sim, tom qab ntawd ntxiv ob qhov txiaj ntsig nruab nrab ua ke thiab coj lub hauv paus square mus. nrhiav tus nyob deb nruab nrab ntawm koj ob lub ntsiab lus.
Kuj nug, qhov deb npaum li cas ib qho khoom yuav poob hauv 5 vib nas this?
Yog li ntawd lub freely poob lub cev poob thaum thawj zaug 5 vib nas this yuav poob 122.5 meters yog tias tsis muaj lwm lub zog ua haujlwm rau nws hauv g = 9.8 m / s ^ 2 (tus qauv tus nqi g). Yog li ntawd lub freely poob lub cev poob thaum thawj zaug 5 vib nas this yuav poob 122.5 meters yog tias tsis muaj kev quab yuam sab nraud ua haujlwm rau nws hauv ib puag ncig tus qauv.
Tus qauv ntawm kev tshaj tawm yog dab tsi?
Velocity Formula . Cov nrawm yog lub sij hawm tus nqi hloov pauv. Yog tias 'S' yog qhov hloov chaw ntawm ib qho khoom hauv qee lub sijhawm 'T', ces qhov nrawm yog sib npaug, v = S/T. Cov units ntawm nrawm yog m/s los yog km/hr.

Koj yuav suav pes tsawg tus hais li cas?
Cov ntsiab lus tseem ceeb 1 mole ntawm cov khoom muaj 6.022 × 1023 hais. 6.022 × 1023 yog hu ua Avogadro Number los yog Avogadro Constant thiab muab lub cim NA (1) N = n × NA N = tus naj npawb ntawm cov khoom hauv cov khoom. Yuav kom nrhiav tau tus naj npawb ntawm cov particles, N, nyob rau hauv ib yam khoom: Nrhiav tus nqi ntawm cov khoom nyob rau hauv moles, n:
Yuav ua li cas koj kwv yees cov pej xeem loj npaum li cas nyob rau hauv lub cim recapture txoj kev?
Cov txheej txheem Mark-Recapture yog siv los kwv yees qhov loj ntawm cov pej xeem uas nws ua tsis tau zoo los suav txhua tus neeg. Lub tswv yim tseem ceeb yog tias koj ntes cov tib neeg tsawg, muab lub cim tsis zoo rau lawv, thiab tso lawv rov qab rau hauv cov pej xeem
Koj puas tuaj yeem kwv yees koj tus menyuam qhov siab?
Tsis muaj pov thawj txoj hauv kev los kwv yees tus menyuam qhov siab ntawm tus neeg laus. Txawm li cas los xij, ntau cov qauv tuaj yeem muab qhov kev kwv yees tsim nyog rau kev loj hlob ntawm menyuam yaus. Nov yog ib qho piv txwv nrov: Ntxiv leej niam qhov siab thiab leej txiv qhov siab ntawm ob ntiv tes lossis centimeters
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
