Izinkinga Ezixazululiwe ku-Physics Eyisisekelo

Amasekethe kagesi anama-resistor ahambisanayo nangaphakathi - izinkinga nezixazululo

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

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

Umthombo we-emf = 24 Volt

Ukumelana kwangaphakathi (r) = 2 Ohm

Ukumelana Ama-ohm angu-40, ama-ohm angu-20, kanye nama-ohm angu-20.

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. amandla kagesi isetshenziswe inyanga (izinsuku ezingu-30)?

Kwaziwa:

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

Amandla we isiqandisi = Ama-Watt angu-200 nesikhathi sokusetshenziswa = amahora angu-24 x 30 = amahora angu-720

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

Izinhlobo zamacala kagesi - izinkinga nezixazululo

1. Ngokusekelwe esithombeni se- amashaja kagesi Ngezansi.

Izinto A no-D zishajelwe kabi (-), into A ukuheha into B kanye iyaxosha into C, into D iyaxosha E. Nquma uhlobo lokushaja kagesi kwezinto B, C, kanye 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 ene-nukubona izindlebe ingafunda incwadi cishe endaweni eyimitha eli-1. Ukuze ifunde ngesikhathi esivamile sokufunda ibanga ka-25 cm, nquma ukuthi amandla elensi okumele asetshenziswe ingane.

Isixazululo:

Ingane iyahlupheka obona kude, lapho iphuzu eliseduze lamehlo akhe liyimitha eli-1 noma i-100 cm. Iphuzu eliseduze leso elivamile lingama-25 cm. Iso lingalungiswa libe ngokwejwayelekile ilensi eqondile.

Amandla e-Kinetic - izinkinga nezixazululo

1. Izimoto ezimbili ziyafana Mass, ukuhamba ngamandla ahlukene e-kinetic. amandla kinetic Imoto yokuqala inamandla okuhamba ngesivinini esiphindwe ka-9 kunemoto yesibili. Ukuqhathaniswa kwesivinini semoto yokuqala nemoto yesibili kungu…..

Kwaziwa:

Imisa yemoto A (m_A) = m

Isisindo semoto B (m_B) = m

Amandla e-kinetic emoto B (K)E_B) = KE

Amandla e-kinetic emoto A (KE_A) = 9 KE
