Lipotoloho tsa motlakase tse nang le li-resistor tse hanyetsanang le tsa kahare - mathata le litharollo
1. Ho latela setšoantšo se ka tlase, haeba mohloli oa matla a motlakase (emf) e le 24 Volts, fumana motlakase oa motlakase I.
Tse tsejoang:
Mohloli oa emf = 24 Volt
Khanyetso ea ka hare (r) = 2 Ohms
Li-resistor tsa 40 Ohm, 20 Ohm, le 20 Ohm.
Ho baloa ha tšebeliso ea matla a motlakase ke lisebelisoa tsa motlakase - mathata le litharollo
1. Ka tlung, ho na le mabone a 5 a sebelisoang ka li-watt tse 25 lihora tse 14 ka letsatsi, sehatsetsi sa li-watt tse 200 se sebelisoang lihora tse 24 ka letsatsi, le pompo ea metsi ea li-watt tse 125 e sebelisoang lihora tse 8 ka letsatsi. Ke matla a makae a motlakase a sebelisoang khoeli (matsatsi a 30)?
Tse tsejoang:
Matla a lebone = 5(25) = 125 Watt le nako ea ts'ebeliso = lihora tse 14 x 30 = lihora tse 420
Matla a sehatsetsi = 200 Watts le nako ea ts'ebeliso = lihora tse 24 x 30 = lihora tse 720
Matla a pompo ea metsi = 125 Watts le nako ea tšebeliso = lihora tse 8 x 30 = lihora tse 240
Mefuta ea litefiso tsa motlakase - mathata le litharollo
1. Ho latela setšoantšo sa litefiso tsa motlakase tse ka tlase.
Lintho A le D li na le chaji e mpe (-), ntho A e hohela ntho B mme e leleka ntho C, ntho D e leleka E. Fumana mofuta oa chaji ea motlakase ea lintho B, C, le E.
A. E ntle, e ntle, e mpe
B. Mpe, Mpe, Mpe
C. E ntle, e mpe, e mpe

Ke sefofane sefe se sekametseng se nang le melemo e tšoanang ea mechini
Ho bona haufi le ho bona hole - mathata le litharollo
1. Ngoana ea nang le bothata ba ho utloa litsebe a ka bala buka a le haufi le mithara e le 'ngoe. E le hore a bale sebakeng se tloaelehileng sa ho bala sa 25 cm, fumana hore na matla a lense a lokela ho sebelisoa ke ngoana.
Tharollo:
Ngoana o na le bothata ba ho bona hole , moo ntlha e haufi ea mahlo a hae e leng mithara e le 'ngoe kapa 100 cm. Ntlha e haufi ea leihlo le tloaelehileng ke 25 cm. Leihlo le ka etsoa hore le be boemong bo tloaelehileng ka lense e kobehileng.
Matla a Kinetic - mathata le litharollo
1. Likoloi tse peli li na le boima bo tšoanang , li tsamaea ka matla a fapaneng a kinetic. Matla a kinetic a koloi ea pele a feta matla a kinetic a koloi ea bobeli ka makhetlo a 9. Papiso ea lebelo la koloi ea pele le koloi ea bobeli ke…..
Tse tsejoang:
Boima ba koloi A (m A ) = m
Boima ba koloi B (m B ) = m
Matla a kinetic a koloi B (K E B ) = K E
Matla a kinetic a koloi A (K E A ) = 9 K E
Lebelo la maqhubu a tšelang – mathata le litharollo
1.
Haeba nako e hlokahalang ho tsamaea ho tloha ho A ho ea ho B e le metsotsoana e 2, fumana lebelo la leqhubu le tšelang.
Tse tsejoang:
Sebaka AB = limithara tse 6 ka motsotsoana
Nako ea nako AB = metsotsoana e 2
Ho batloa: Lebelo la maqhubu a tšelang
Mahlaseli a kotsi - mathata le litharollo
1. Ho latela setšoantšo se ka tlase, ts'ebetso ea mahlaseli a kotsi ka mor'a ho bola ka lihora tse 13.86 ke ...
Tse tsejoang:
Halofo ea bophelo (T 1/2 ) = lihora tse 6.93
Nako e fela (t) = lihora tse 13.86
Ho batloa: mosebetsi oa mahlaseli a kotsi
