Musoro wekuyedza: Kuedza kwaMelde
Chinangwa chekuedza: Kuongorora hukama huripo pakati pekumanikidzwa kwetambo, urefu hwemafungu uye kumhanya kwekupararira kwemafungu.
Zvishandiso nezvinhu: Chinotora nguva, tambo, pulley, huremu hwemagiramu makumi mashanu, simba remagetsi, zvikero, rula.
Dzidziso huru:
Kumhanya kwekupararira kwemafungu kunoratidzwa ne equation:
v = λ f
Information :
v = kumhanya kwekuparadzira mafungu
λ = kureba kwehurefu
f = kakawanda
Mafungu anopararira patambo kana tambo mafungu anotenderera . Kumhanya kwemafungu anotenderera patambo kunogona kuverengerwa uchishandisa fomura:
Information :
v = kumhanya kwemafungu patambo (mita/sekondi)
F = T = simba rekusunga tambo (Newton)
μ = huremu pahuniti imwe neimwe kureba kwetambo (kirogiramu/mita)
Matanho Ekuyedza:
1. Yera huremu hwetambo uchishandisa chikero
Huremu hwetambo = ..........giramu = ..........kg
2. Yera kureba kwetambo uchishandisa rula.
Kureba kwetambo (l) =……….cm = …….m
3. Verenga huwandu hwetambo
μ = m / l = …….kg/m
Isa mutafura yedata, koramu yehuwandu hwetambo, mutsetse wekutanga.
4. Unganidza michina yekuyedza sezvakaratidzwa mumufananidzo. Mugumo mumwe wetambo wakabatana nemutoro we50 gram.
5. Yera kureba kwetambo kubva kumucheto mumwe wakasungirirwa kusvika kune mumwe wakasungirirwa.
Kureba kwetambo (l) = ..cm = ..m
6. Batidza ticker timer kusvika wave yakamira yaumbwa patambo. Verenga huwandu hweanti-waves. Huwandu hweanti-waves = …………
Ngatitii kune matumbu n, saka daro riri pakati pedumbu rimwe = kureba kwetambo (l) / n = x
Daro dumbu 1 (x) = 1/2 urefu hwemafungu (1/2 λ)
1 wavelength (λ) = 2 x =……….. m
Isa mudhatafura yedata, koramu yewavelength, mutsetse wekutanga.
7. Mafambiro emafungu = mapindiro enguva yekutenderera nguva = mapindiro ePLN = 50 Hertz
8. Verenga kumhanya kwekupararira kwemafungu
v = f λ =………..m/s
Pinda mutafura yedata, koramu yekumhanya kwemafungu, mutsetse wekutanga.
9. Dzokorora danho rechina, uchishandisa huremu hwemagiramu zana.
Isa data mutafura, mutsetse wechipiri.
10. Dzokorora danho rechina, uchishandisa huremu hwemagiramu zana.
Isa data mutafura, mutsetse wechitatu.
Data:
Huremu hwemutoro (m) = magiramu makumi mashanu = (50/1000) kg = (5/100) kg = 0,05 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Kurema kwemutoro (w) = mg = (0,05 kg)(10 m/s 2 ) = 0,5 kg m/s 2 = 0,5 N
Kurema kwemutoro (w) = simba rekumanikidzwa mutambo (F)

Kuongorora data:
- Chii chiri hukama huripo pakati pekumanikidzwa kwetambo nehukuru hwewavelength?
- Chii chiri hukama huripo pakati pekumanikidzwa kwetambo nekumhanya kwekupararira kwemafungu?
- Hukama huripo pakati pewavelength nekumhanya kwemafungu?
