Qhov ceev ntawm lub suab hauv huab cua yog txiav txim siab los ntawm huab cua nws tus kheej thiab tsis nyob ntawm qhov amplitude, zaus, lossis wavelength ntawm lub suab. Rau cov roj zoo tagnrho qhov ceev ntawm lub suab tsuas yog nyob ntawm nws kub thiab yog ywj siab ntawm gas siab.
Ua kom pom qhov no, qhov ceev ntawm lub suab nyob ntawm seb yog dab tsi?
Cov ceev lub suab nyob ntawm lub elasticity thiab ntom ntawm qhov nruab nrab los ntawm nws mus ncig. Feem ntau, suab taug kev nrawm dua hauv cov kua ntau dua hauv cov pa roj thiab sai dua hauv cov khoom khov dua li cov kua. Qhov ntau dua qhov elasticity thiab qis dua qhov ntom, qhov nrawm dua suab taug kev hauv nruab nrab.
Dab tsi yog qhov ceev ntawm lub suab nyob ntawm quizlet? Cov ceev lub suab nyob ntawm nyob rau ntawm qhov tawv nqaij nruab nrab. Suab taug kev nrawm dua hauv cov xov xwm nruj vim tias thaum cov khoom nruab nrab yog compressed, lawv sai sai kis tawm dua. Suab taug kev nrawm tshaj plaws hauv cov khoom khib nyiab, tom qab ntawd cov kua thiab qeeb tshaj plaws hauv cov pa.
Qhov thib ob, dab tsi yog qhov tseem ceeb ntawm qhov ceev ntawm lub suab hauv nruab nrab nyob ntawm?
Qhov ceev ntawm lub suab yog nyob ntawm qhov ceev thiab viscosity ntawm qhov nruab nrab los ntawm qhov uas nws propagates. Yog li kub , av noo (yog tias tsis yog kua nruab nrab) thiab siab kuj yog yam tseem ceeb raws li lawv cuam tshuam qhov ntom thiab viscosity ntawm nruab nrab, tshwj xeeb tshaj yog tias lub suab nthwv dej nthuav tawm los ntawm cov kua dej.
Dab tsi yog qhov ceev ntawm lub suab hauv kua?
Suab taug kev nrawm dua hauv kua tshaj nyob rau hauv gases vim hais tias molecules yog nruj nreem packed. Hauv dej tshiab, suab nthwv dej ntawm 1,482 meters ib ob (kwv yees 3,315 mph).

Cov nqe lus twg zoo tshaj plaws piav qhia txog qhov tseem ceeb ntawm cov lus qhia muaj nuj nqis?
Qhov tsis suav nrog tus nqi ntawm ib qho kev qhia rational yog qhov tseem ceeb uas tus denominator ntawm qhov kev qhia yog xoom. Tsis tas li ntawd, tus naj npawb ntawm zeros ntawm ib tug polynomial yeej ib txwm tsawg dua los yog sib npaug rau degree ntawm lub polynomial. Yog li ntawd, tus naj npawb ntawm cov txiaj ntsig tsis suav nrog cov lus qhia muaj txiaj ntsig tsis tuaj yeem tshaj li qib ntawm tus lej
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Vim li cas cov haujlwm muaj nuj nqis muaj kev txwv?
Domain txwv tsis pub muaj nuj nqi muaj nuj nqis tuaj yeem txiav txim siab los ntawm kev teeb tsa tus lej sib npaug rau xoom thiab daws. Cov x -values uas tus denominator sib npaug zero yog hu ua singularities thiab tsis nyob rau hauv lub domain ntawm lub functionality
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
Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog lub zog muaj nuj nqi?
VIDEO Ib yam li ntawd, tib neeg nug, dab tsi ua rau lub zog ua haujlwm? A lub zog ua haujlwm yog a muaj nuj nqi qhov twg y = x ^n qhov twg n yog tus lej tiag tiag. Ntau tus niam txiv muaj nuj nqi xws li linear muaj nuj nqi thiab quadratic muaj nuj nqi yog qhov tseeb lub zog ua haujlwm .
