Amasekethe kagesi anama-resistor ahambisanayo nangaphakathi - izinkinga nezixazululo

1. Ngokusekelwe esithombeni esingezansi, uma umthombo wamandla kagesi (emf) ungama-volt angu-24, nquma ugesi I.

Kwaziwa: Amasekethe kagesi anama-resistor ahambisanayo nangaphakathi - izinkinga nezixazululo 1

Umthombo we-emf = 24 Volt

Ukumelana kwangaphakathi (r) = 2 Ohm

Ama-Resistors angu-40 Ohm, 20 Ohm, kanye no-20 Ohm.

Ukubalwa kokusetshenziswa kwamandla kagesi ngamathuluzi kagesi - izinkinga nezixazululo

1. Endlini, kunezibani ezi-5 ezingama-25 Watt ezisetshenziswa amahora ayi-14 ngosuku, isiqandisi sama-200 Watt esisetshenziswa amahora angama-24 ngosuku, kanye nephampu yamanzi engama-125 Watt esetshenziswa amahora ayi-8 ngosuku. Kusetshenziswa amandla kagesi angakanani inyanga yonke (izinsuku ezingama-30)?

Kwaziwa:

Amandla esibani = 5(25) = 125 Watt kanye nesikhathi sokusebenzisa = amahora ayi-14 x 30 = amahora angama-420

Amandla esiqandisi = 200 Watts kanye nesikhathi sokusebenzisa = 24 hours x 30 = 720 hours

Amandla epompo yamanzi = 125 Watts kanye nesikhathi sokusetshenziswa = amahora angu-8 x 30 = amahora angu-240

Izinhlobo zamacala kagesi - izinkinga nezixazululo

1. Ngokusekelwe esifanekisweni samanani kagesi angezansi.

Izinto A no-D zishajwa kabi (-), into A idonsela into B futhi ixosha into C, into D ixosha u -E. Nquma uhlobo lweshaja kagesi yezinto B, C, no-E.

A. Okuhle, Okuhle, Okubi

B. Okubi, Okubi, Okuhle

C. Okuhle, Okubi, Okubi

D. Okuhle, Okubi, Okuhle

Ukubuka eduze nokubona kude - izinkinga nezixazululo

1. Ingane engakwazi ukubona kahle ingafunda incwadi cishe ngemitha eli-1. Ukuze ifunde ibanga elijwayelekile lokufunda elingama-25 cm, nquma ukuthi ingane kufanele isebenzise amandla ngelensi.

Isixazululo:

Ingane inenkinga yokubona kude , lapho iphuzu eliseduze lamehlo ayo liyimitha eli-1 noma i-100 cm. Iphuzu eliseduze leso elivamile liyi-25 cm. Iso lingalungiswa libe ngokwejwayelekile ngelensi egobile.

Amandla e-Kinetic - izinkinga nezixazululo

1. Izimoto ezimbili zinesisindo esifanayo , zihamba ngamandla ahlukene e-kinetic. Amandla e-kinetic emoto yokuqala aphindwe ka-9 kunamandla e-kinetic emoto yesibili. Ukuqhathaniswa kwesivinini semoto yokuqala nemoto yesibili kungu…..

Kwaziwa:

Isisindo semoto A (m _A) = m

Isisindo semoto B (m _B) = m

Amandla e-kinetic emoto B (K E _B) = K E

Amandla e-kinetic emoto A (K E _A) = 9 K E
