Ib yam li ntawd, tib neeg nug, qhov ceev teb yog dab tsi?
Ntsiab Lub tswv yim Qhov loj ntawm atoms, lawv qhov loj me, thiab lawv tau npaj li cas los txiav txim siab qhov ceev ntawm ib yam khoom. Qhov ntom sib npaug qhov loj ntawm cov khoom faib los ntawm nws ntim; D = m/v.
Tom qab ntawd, lo lus nug yog, ua li cas koj pom qhov ntom ntawm lub pob balling? Sai li koj paub cov ntim ntawm lub bowling pob , koj tuaj yeem yooj yim xam tus pob qhov ntom los ntawm kev faib qhov hnyav ntawm cov pob (hauv grams) los ntawm qhov ntim (5,452 cm3). Hloov qhov hnyav ntawm lub pob los ntawm phaus mus rau grams, siv qhov hloov pauv ntawm 1 phaus = 453.6 grams (tab sis peb yuav hloov mus txog 454 grams).
Dab tsi yog qhov kev sib raug zoo ntawm huab hwm coj thiab ntim?
Pawg yog tus nqi ntawm cov khoom uas muaj, thaum ntim yog qhov chaw ntau npaum li cas nws siv. Piv txwv li: Lub pob bowling thiab pob basketball yog hais txog tib yam ntim ib leeg, tab sis lub pob bowling muaj ntau yam ntxiv pawg.
Qhov txawv ntawm qhov ntom ntom thiab ntim yog dab tsi?
Pawg , ntim thiab ceev yog peb ntawm ib yam khoom uas yooj yim tshaj plaws. Pawg yog qhov hnyav npaum li cas, ntim qhia koj tias nws loj npaum li cas, thiab ceev yog pawg faib los ntawm ntim . Txawm tias hnyav thiab ntim yog cov khoom koj nrog txhua hnub, lub tswv yim ntawm ceev yog me ntsis tsis pom tseeb thiab ua tib zoo xav.

Koj yuav ua li cas paub yog tias qhov hloov pauv theem yog qhov zoo lossis tsis zoo?
Yog tias lub sijhawm hloov pauv yog xoom, qhov nkhaus pib ntawm keeb kwm, tab sis nws tuaj yeem txav mus rau sab laug lossis sab xis nyob ntawm theem hloov. Kev hloov pauv theem tsis zoo qhia txog kev txav mus rau sab xis, thiab theem zoo hloov pauv qhia tias txav mus rau sab laug
Lub hauv paus ntsiab lus twg ntawm kev txheeb ze koj tau siv los txiav txim siab seb pob zeb txheej H yog laus dua lossis hluas dua txheej?
Lub hauv paus ntsiab lus ntawm superposition yog yooj yim, intuitive, thiab yog lub hauv paus rau cov txheeb ze hnub nyoog sib tam. Nws hais tias cov pob zeb nyob hauv qab lwm cov pob zeb yog cov laus dua li cov pob zeb saum toj no
Yuav ua li cas koj thiaj paub yog tias koj lub tsev nyob rau hauv lub dab dej?
Ntawm no yog 7 lub cim qhia ntau tshaj plaws hauv lub dab dej yuav tshwm sim: Ib puag ncig kev nyuaj siab nyob rau hauv lub ntiaj teb: Localized subsidence los yog kev nyuaj siab nyob txhua qhov chaw ntawm lub tsev: Lub pas dej ncig (los yog lub pas dej loj, tob): Lub hauv paus daws teeb meem: Kev tawg ntawm txoj kev lossis pavement : Cia li poob ntawm qhov dej hauv qhov chaw:
Koj yuav paub li cas yog lub chaw chiral yog R lossis S?
Kos ib qho nkhaus los ntawm thawj qhov tseem ceeb hloov pauv mus rau qhov thib ob-qhov tseem ceeb hloov pauv thiab tom qab ntawd los ntawm qhov thib peb. Yog hais tias qhov nkhaus mus clockwise, lub chiral center yog xaiv R; Yog hais tias qhov nkhaus mus counterclockwise, lub chiral center yog xaiv S
Koj yuav paub li cas yog qhov sib npaug yog linear lossis nonlinear?
Siv ib qho Equation Simplify qhov sib npaug kom ze li sai tau rau daim ntawv y = mx + b. Tshawb xyuas seb koj qhov kev sib npaug puas muaj cov exponents. Yog hais tias nws muaj exponents, nws yog nonlinear. Yog tias koj qhov kev sib npaug tsis muaj tus lej, nws yog linear
