Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog echolocation menyuam tus phooj ywg txhais?
Echolocation yog ib txoj hauv kev uas qee cov tsiaj siv los txiav txim qhov chaw ntawm cov khoom. Lawv emit suab nthwv dej thiab mloog rau ncha. Lawv siv qhov ncua sij hawm los txiav txim qhov kev ncua deb. Nws yog ib hom kev lom neeg sonar. Lawv lub suab nthwv dej mus rau hauv dej, thaum cov puav suab nthwv dej mus rau saum huab cua
Puas yog pH 11 yog acid ib puag ncig lossis nruab nrab?
Lub pH ntawm 7 yog nruab nrab. pH tsawg dua 7 yog acidic. Ib qho pH ntau dua 7 yog qhov yooj yim. Qhov pH nplai yog logarithmic thiab vim li ntawd, txhua tus nqi pH qis dua 7 yog kaum npaug ntau acidic dua li tus nqi siab dua tom ntej
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev xaiv cov phooj ywg thiab kev xaiv pab pawg?
Kev xaiv Kin, hais lus ntxhib, yog kev xaiv ntawm qhov sib txawv ntawm qhov tsis ncaj ncees (rb ≠ 0) uas tshwm sim hauv cov neeg siab-K (cov pej xeem uas muaj kev sib raug zoo ntawm cov txheeb ze); whereas kev xaiv pab pawg, kwv yees hais lus, yog kev xaiv ntawm qhov sib txawv ntawm qhov tsis muaj zog (rb ≠ 0) uas tshwm sim hauv cov neeg siab-G (cov pej xeem
