Lub joule ib ob yog ib chav ntsuas ntawm lub zog
SI unit ntawm lub zog yog joule ib ob ( J / sec ). Chav tsev muaj lub npe tshwj xeeb, watt (W), tom qab Scottish inventor thiab mechanical engineer James Watt.
Kuj nug, J S sib npaug li cas?
Lub watts chav tsev naj npawb 1.00 W converts rau 1 J / s , ib joule per second. Nws yog tus Sib npaug hwj chim tus nqi ntawm 1 joule ib ob tab sis nyob rau hauv lub watts hwj chim unit lwm txoj.
Tsis tas li ntawd, chav tsev twg yog kg / m2 s2? SI Derived thiab SI Compatible Units
| Derived Unit | Kev ntsuas | Lus Txhais |
|---|---|---|
| Newton (N) | zog | kg · m-2 |
| Pascal (Pa) | siab | kg · m-1·s-2 |
| joule (J) | zog los yog ua hauj lwm | kg · m2·s-2 |
| watt (W) | zog | kg · m2·s-3 |
Yog li ntawd, dab tsi yog joule hauv cov ntsiab lus yooj yim?
Cov joule ua (pronounced DJOOL) yog tus qauv chav tsev ntawm lub zog nyob rau hauv electronics thiab kev siv scientific. Ib joule ua txhais tau tias yog tus nqi ntawm lub zog exerted thaum lub zog ntawm ib tug newton yog siv tshaj ib tug 'meter'.
Ib watt sib npaug rau ib joule ib ob?
Cov wat ob yog ib chav tsev ntawm lub zog, sib npaug mus rau joule ua . Ib kilowatt teev yog 3,600,000 watt vib nas this.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Dab tsi yog qhov ntsug asymptote ntawm sec x?
Vertical asymptotes rau y = sec(x) y = sec (x) tshwm sim ntawm −π2,3π2 3 π 2, thiab txhua tus π n, qhov twg n yog tus lej. Qhov no yog ib nrab ntawm lub sijhawm. Muaj tsuas yog ntsug asymptotes rau secant thiab cosecant functions
