Magulu a Gurumuda
1. Kutengera chithunzi chomwe chili pansipa, ngati utali wa kupindika kwa waya ndi 50 cm, dziwani kukula kwa mphamvu ya maginito pakati pa kupindika (pa mfundo 0, onani chithunzi pansipa). (µ o = 4π.10 -7 Wb.A -1 m -1 )
Zodziwika:
Utali wozungulira (r) = 50 cm = 0.5 m
Mphamvu yamagetsi (I) = 1.5 Ampere
Kutuluka kwa vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Kufunidwa: Kukula kwa mphamvu ya maginito
3 EMF Yoyambitsidwa ndi Magetsi - Mavuto ndi Mayankho
1. Chokokeracho chasinthidwa ndi chokokera china chomwe chili ndi malupu owirikiza kawiri kuposa malupu oyamba ndipo liwiro la kusintha kwa maginito limakhala losasintha. Dziwani chiŵerengero cha emf yoyambira ndi yomaliza yomwe yayambitsidwa.
Zodziwika:
Malupu oyamba (N) = 1
Mapeto ozungulira (N) = 2
Mlingo wa kusintha kwa maginito oyamba (ΔØ B / Δt) = mlingo wa kusintha kwa maginito omaliza (ΔØ B / Δt)
1. Kutengera ndi equation yotsatirayi ya fusion reaction , dziwani mphamvu yopangidwa mu fusion reaction!
Anakonza
1. Kutengera chithunzi chomwe chili pansipa, dziwani mphamvu yamagetsi kudzera mu R 1.
Zodziwika:
Wotsutsa 1 (R1 ) = 4 Ω
Wotsutsa 2 (R2 ) = 4 Ω
Wotsutsa 3 (R3 ) = 8 Ω
Mphamvu yamagetsi (V) = 40 Volts
Mafunde atatu a makina (Kutalika kwa Mafunde a Nthawi Yozungulira Liwiro la mafunde) - Mavuto ndi Mayankho
1. Zitseko ziwiri zili pamwamba pa mafunde . Zonse zimakwera ndi kutsika pamwamba pa nyanja nthawi 20 mu masekondi 4. Ngati mtunda wa zitseko zonse ziwiri ndi 100 cm ndipo pakati pawo pali zitseko ziwiri ndi chitseko chimodzi, dziwani kuchuluka kwa mafunde ndi liwiro la mafunde.
Zodziwika:
Ma corks onsewa ali pamwamba pa mafunde ndipo pakati pa ma corks awiriwa, pali ma troughs awiri ndi crest imodzi (onani chithunzi). Chifukwa chake, pali ma wavelength awiri pakati pa ma corks awiriwa.
Kusokonezeka ndi mpata umodzi - mavuto ndi mayankho
1. Kuwala kokhala ndi mafunde a 500 nm kumadutsa mpata wa 0.2 mm mulifupi. Kapangidwe ka diffraction pa sikirini 60 cm kutali. Dziwani mtunda pakati pa maximum yapakati ndi maximum yachiwiri.
Zodziwika:
Kuyesera kwa Young kwa double-slit - mavuto ndi mayankho
1. d ndi mtunda pakati pa mipata iwiri, L ndi mtunda pakati pa mipata ndi sikirini yowonera, P 2 ndi mtunda pakati pa fringe yachiwiri ndi pakati pa sikirini. Dziwani kutalika kwa mafunde a kuwala (1 Å = 10 -10 m).
Zodziwika:
Mtunda pakati pa mipata iwiri (d) = 1 mm = 1 x 10 -3 m
Mtunda pakati pa mpata ndi chophimba chowonera (L) = 1 m
Mtunda pakati pa mphero yachiwiri ndi mphero yapakati (P 2 ) = 1 mm = 1 x 10 -3 m
Dongosolo (n) = 2
1. Chinthu chozungulira chopanda kanthu (I = m R 2 ) chimayenda kuti chizungulire popanda kutsetsereka pamwamba pa mtunda wozungulira mozungulira ndi liwiro loyambirira la 10 m/s. Mtundu wozungulira uli ndi ngodya yokwezeka θ yokhala ndi tan θ = 0.75. Ngati mphamvu yokoka g = 10 ms -2 , liwiro la chinthucho limachepetsedwa kufika pa 5 ms -1 ndiye kuti mtunda womwe uli pa mtunda wozungulira wa chinthucho ndi…
Zodziwika:
Nthawi ya kulephera kwa silinda yopanda kanthu (I) = m R 2
Ngodya yokwezeka = θ , pomwe tan θ = 0.75 = 75/100 = opp / adj
Tchimo θ = opp / hyp = 75/125 = 3/5 = 0.6
Kuthamanga chifukwa cha mphamvu yokoka (g) = 10 m/s 2
Liwiro loyambirira (v o ) = 10 m/s
Liwiro lomaliza (v t ) = 5 m/s
