Thaum Lub Yim Hli 4, 2020, lub cache ntawm kwv yees li 2750 metric tons ntawm ammonium nitrate precariously khaws cia nyob rau hauv qhov chaw nres nkoj ntawm Beirut, Lebanon ignited thiab teeb tawm ib qho kev txiav txim siab loj heev tawg uas rhuav tshem ntau qhov chaw ntawm lub nroog qub.

Thaum lub TV xim tawm hauv tebchaws Ltalis xyoo 1970, cov tub ceev xwm hauv nroog tau tshem tawm TV feem ntau thov tias lawv tsis ua qhov kev sim txaus thiab lawv tuaj yeem ua rau muaj kev phom sij rau cov neeg saib. Tej zaum lawv hais yog lawm, tej zaum tsis yog. Lub ntsiab lus yog tias nws yog kev cuam tshuam kev siv tshuab uas tsoomfwv tau sim tswj hwm vim lawv tsis nkag siab.
Lwm qhov piv txwv yog internet.
Qhov tshwm sim ntawm electromagnetic induction tau pom los ntawm Michael Faraday thiab Joseph Henry, cov txiaj ntsig ntawm thawj qhov kev sim qhia txog qhov tshwm sim ntawm electromagnetic induction yog luam tawm xyoo 1931 los ntawm Faraday. Qhov tshwm sim ntawm electromagnetic induction muaj nyob rau hauv cov tsos ntawm induced electromotive voltage thiab induced tam sim no nyob rau hauv ib tug Circuit Court hla los ntawm lub sij hawm-hloov sib nqus flux. Ib qho kev sim yooj yim piav qhia txog qhov tshwm sim yog pom hauv daim duab 1. Peb muaj ib lub kauj ntawm lub terminals uas peb txuas ib milliammeter ua ib lub voj voog kaw. Peb nqa ib lub hlau nplaum nyob ib puag ncig ntawm lub voj voog no. Yog tias cov hlau nplaum nyob ntawm qhov chaw, lub ammeter tsis qhia txog tam sim no. Yog hais tias cov hlau nplaum txav rov qab los ntawm lub kauj hloov lub koob ntawm lub ammeter deviates qhia tias muaj nyob rau hauv lub kauj voj voog ntawm ib tug tam sim no hu ua induced tam sim no uas qhia tau hais tias qhov system no (coil + hlau nplaum) coj zoo li lub tshuab hluav taws xob, lub electromotive voltage. tshwm sim hu ua voltage induced electric motors.
SLP hais lus pathology suab sticker
Txhua leej txhua tus tab tom tham txog kev ua tsov rog hauv UKRAINE, ntseeg tias lawv tau pom txoj hauv kev los hais lus. Cov lus hais uas peb yuav tsum muaj txhua hnub kuv tsis xav tias yog TSHIAB TSHIAB!
