Maseketi emagetsi ane ma resistors akafanana uye emukati - matambudziko nemhinduro
1. Zvichibva pamufananidzo uri pazasi, kana sosi yesimba remagetsi (emf) iri 24 Volts, sarudza magetsi emagetsi I.
Zvinozivikanwa:
Kunobva emf = 24 Volt
Kudzivirira kwemukati (r) = 2 Ohms
Zvinopikisa 40 Ohm, 20 Ohm, uye 20 Ohm.
Kuverengwa kwekushandiswa kwesimba remagetsi nezvishandiso zvemagetsi - matambudziko nemhinduro
1. Mumba, mune marambi mashanu ane maWatts makumi maviri nemashanu anoshandiswa maawa gumi nemana pazuva, firiji ine maWatts mazana maviri nemana pazuva, uye pombi yemvura ine maWatts zana nemakumi maviri neshanu inoshandiswa maawa masere pazuva. Simba remagetsi ringani rinoshandiswa kwemwedzi (mazuva makumi matatu)?
Zvinozivikanwa:
Simba rerambi = 5(25) = 125 Watts uye nguva yekushandisa = maawa 14 x 30 = maawa 420
Simba refiriji = 200 Watts uye nguva yekushandisa = maawa makumi maviri nemana x 30 = maawa mazana manomwe nemakumi maviri
Simba repombi yemvura = 125 Watts uye nguva yekushandisa = maawa masere x 30 = maawa mazana maviri nemakumi mana
Mhando dzemagetsi anochaja - matambudziko nemhinduro
1. Zvichibva pamufananidzo wemagetsi ari pazasi.
Zvinhu A naD zvinochajiwa zvisina kunaka (-), chinhu A chinokwezva chinhu B uye chinodzinga chinhu C, chinhu D chinodzinga E. Sarudza rudzi rwechaji yemagetsi yezvinhu B, C, naE.
A. Zvakanaka, Zvakanaka, Zvakaipa
B. Kuipa, Kuipa, Kunaka
C. Zvakanaka, Zvakaipa, Zvakaipa
D. Zvakanaka, Zvakaipa, Zvakanaka
6 Muchina uri nyore (Inclined plane Lever) - Matambudziko nemhinduro
1.
Ndeipi ndege yakakotama ine mukana wakafanana wemakanika
Kuona zviri pedyo uye kuona zviri kure - matambudziko nemhinduro
1. Mwana ane ruzivo rwekunzwa anogona kuverenga bhuku ari pedyo nemita imwe chete. Kuti averenge ari padanho rekuverenga re25 cm, sarudza kuti simba relenzi rinofanira kushandiswa nemwana.
Solution:
Mwana anoona zviri kure , uko nzvimbo iri pedyo nemaziso ake iri mita imwe kana 100 cm. Nzvimbo iri pedyo nemaziso ake iri 25 cm. Ziso rinogona kugadziriswa zviri nyore ne lenzi ine convex.
Kinetic simba - matambudziko uye mhinduro
1. Mota mbiri dzine huremu hwakafanana , dzichifamba nesimba rekufamba rakasiyana. Simba rekufamba remota yekutanga rinopetwa ka9 kupfuura simba rekufamba remota yechipiri. Kuenzanisa kumhanya kwemota yekutanga nemota yechipiri ndekwekuti…..
Zvinozivikanwa:
Huremu hwemota A (m A ) = m
Huremu hwemota B (m B ) = m
Simba rekufamba kwemotokari B (K E B ) = K E
Simba rekufamba kwemotokari A (K E A ) = 9 K E
Kumhanya kwemafungu anochinjika - matambudziko nemhinduro
1.
Kana nguva inodiwa kuti munhu afambe kubva kuA kuenda kuB iri masekondi maviri, sarudza kumhanya kwewave inochinjika.
Zvinozivikanwa:
Kureba AB = mamita matanhatu pasekondi
Nguva yepakati AB = masekondi maviri
Zvinodiwa: Kumhanya kwemafungu anochinjika
Matambudziko eRadioactivity - uye mhinduro dzawo
1. Zvichibva pamufananidzo uri pazasi, basa remwaranzi mushure mekuora kwemaawa 13.86 ndiro …
Zvinozivikanwa:
Hafu yehupenyu (T 1/2 ) = maawa 6.93
Nguva-inopera (t) = maawa 13.86
Zvinodiwa: basa remwaranzi
Skuruu yeMicrometer - matambudziko nemhinduro
1. Kuyerwa kwedhayamita yewaya ine micrometer ndeye 2.48 mm. Mufananidzo unoenderana nemhedzisiro yekuyerwa ndewekuti…
