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 I.
Tse tsejoang:
Mohloli oa emf = 24 Volt
Khanyetso ea ka hare (r) = 2 Ohms
Mohanyetsi 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 25 Watt a sebelisoang lihora tse 14 ka letsatsi, sehatsetsi sa 200 Watt se sebelisoang lihora tse 24 ka letsatsi, le pompo ea metsi ea 125 Watt e sebelisoang lihora tse 8 ka letsatsi. matla a motlakase e sebelisitsoe 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 = Li-watt tse 200 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 ipapisitsoe le setšoantšo sa litefiso tsa motlakase mona ka tlase.
Lintho A le D li na le chaji e mpe (-), ntho A hohela ntho B le leleka ntho C, ntho D leleka E. Fumana qeto mofuta oa tjhaja 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

Mochini o 6 o bonolo (Lever e sekametseng) - Mathata le Litharollo
1.
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 nho bona litsebe a ka bala buka a le haufi le ntlha ya mithara e le 1. E le hore a bale ka nako e tloaelehileng distanta ea 25 cm, fumana hore na matla a lense a tlameha ho sebelisoa ke ngoana.
Tharollo:
Ngoana oa utloa bohloko ponelopele, 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 nyenyefalitsoeng.
Matla a Kinetic - mathata le litharollo
1. Likoloi tse peli li na le tse tšoanang boima, ho tsamaea ka matla a fapaneng a kinetic. matla a kinetic ea koloi ea pele e 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:
Boholo ea koloi A (mA) = m
Boima ba koloi B (mB) = m
Matla a kinetic a koloi B (K)EB) = KE
Matla a kinetic a koloi A (KEA) = 9 KE
Lebelo la maqhubu a tšelang – mathata le litharollo
1.
Haeba nako e hlokahalang ho tsamaea ho tloha A ho ea ho B e le metsotsoana e 2, fumana lebelo la leqhubu le tšelang.
Tse tsejoang:
distanta AB = limithara tse 6s
Nako ea nako AB = 2 metsotsoana
Oa Batla: Lebelo la leqhubu le tšelang
Mahlaseli a kotsi - mathata le litharollo
1. Ho latela setšoantšo se ka tlase, e tsoekere haholo ts'ebetso kamora 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
Oa Batla: mosebetsi oa mahlaseli a kotsi
Sekurufu sa micrometer - mathata le litharollo
1. Tekanyo ea bophara ba terata ka micrometer ke 2.48mm. Setšoantšo se tsamaellanang le sephetho sa tekanyo ke…
