Mafunde ozungulira ndi aatali - mavuto ndi mayankho

Mafunde ozungulira ndi aatali - mavuto ndi mayankho

1. Mafunde akuyenda pansi pa waya wautali mamita atatu kwa masekondi 0.3. Kodi nthawi ya mafunde ndi yotani?

Zodziwika:

Nthawi yopuma (t) = masekondi 0.3

Akufuna: Nthawi (T)

Yankho:

Kutalika kwa mtunda umodzi = 1 crest + 1 threy

Nthawi = 2 x 0.1 masekondi = 0.2 masekondi

2. Liwiro la mafunde malinga ndi chithunzi chili pansipa ndi…

Zodziwika:

Kutalika kwa thambo limodzi kuli ndi chivundikiro chimodzi ndi chidebe chimodzi. Malinga ndi chithunzi pamwambapa, kutalika kwa thambo limodzi = mamita awiri x 4 = mamita 8.

Nthawi ya mafunde (T) = 0.5 x 4 = masekondi awiri

Kufunidwa: Liwiro la mafunde (v)

Yankho:

Liwiro la mafunde:

v = s / t = λ / T = mamita 8 / masekondi awiri = mamita 4/sekondi

3. Mtunda pakati pa mfundo A ndi B ndi 30 cm. Kodi liwiro la mafunde ndi lotani malinga ndi chithunzi chili pansipa?

Zodziwika:

Kuchokera pa A mpaka B, pali ¾ wavelength. Ngati mtunda pakati pa A ndi B ndi 30 cm, ndiye kuti mtunda wa ¼ wavelength ndi 30 cm / 3 = 10 cm. Motero, 1 wavelength = 4 x 10 cm = 40 cm.

Malinga ndi chithunzi pamwambapa, nthawi ya mafunde ndi masekondi anayi.

Kufunidwa: Liwiro la mafunde (v)

Yankho:

v = d / t = λ / t

v = liwiro la mafunde, d = mtunda, λ = kutalika kwa mafunde, t = nthawi yopuma

Liwiro la mafunde:

v = λ / t = 40 cm / masekondi 4 = 10 cm / sekondi imodzi = 10 cm/sekondi

4. Ngati mtunda wa A ndi B = 250 cm, ndiye kuti liwiro la mafunde ndi…

Zodziwika:

Mtunda wa A ndi B = 5/4 kutalika kwa mtunda = 250 cm.

1/4 kutalika kwa mtunda = 250 cm / 5 = 50 cm

Kutalika kwa mtunda umodzi = kutalika kwa mtunda wa 4/4 = 4 x 50 cm = 200 cm

Nthawi (T) = masekondi 2

Kufunidwa: Liwiro la Mafunde

Yankho:

Fomula ya liwiro la mafunde:

v = d / t = λ / t

v = liwiro la mafunde, d = mtunda λ = kutalika kwa mafunde, t = nthawi yopuma

Liwiro la mafunde:

v = 200 cm / masekondi awiri = 100 cm/sekondi

5. Kukula kwa mafunde kumawonetsedwa ndi….

Yankho:

Kutalika kwa mafunde ndi BB' ndi DD”.

1. Kodi n’chiyani chimasiyanitsa mafunde opingasa ndi mafunde a longitudinal pankhani ya kayendedwe ka tinthu?
   • yankho: Mu mafunde opingasa, tinthu tating'onoting'ono ta sing'anga timayenda molunjika ku mbali ya kufalikira kwa mafunde. Mu mafunde a longitudinal, tinthu tating'onoting'ono timayenda molunjika ku mbali ya kufalikira kwa mafunde.
2. Amapereka chitsanzo chodziwika bwino cha mafunde opingasa ndi mafunde a longitudinal.
   • yankhoChitsanzo chodziwika bwino cha mafunde opingasa ndi mafunde pa chingwe kapena mafunde amadzi. Chitsanzo chodziwika bwino cha mafunde a longitudinal ndi mafunde a phokoso mumlengalenga.
3. Kodi zinthu zolimba zimathandiza mafunde opingasa komanso aatali?
   • yankhoInde, zinthu zolimba zimatha kuthandizira mafunde opingasa komanso akutali. Komabe, madzi (mpweya ndi zakumwa) nthawi zambiri zimangothandizira mafunde akutali.
4. Kodi kupsinjika ndi kusinthasintha kwa mafunde kumagwirizana bwanji ndi mafunde a longitudinal?
   • yankho: Mu mafunde a longitudinal, compression imatanthauza dera lomwe tinthu ta medium tili pafupi kwambiri, ndipo rarefaction imatanthauza dera lomwe tinthu tating'onoting'ono tili kutali kwambiri. Madera awa amafanana ndi ma crests ndi ma troughs mu mafunde opingasa.
5. N’chifukwa chiyani timamva phokoso (mafunde aatali) mozungulira ngodya koma osawona kuwala (komwe kumachita ngati mafunde opingasa) mwanjira yomweyo?
   • yankho: Phokoso limatha kusokoneza, kapena kufalikira, mozungulira zopinga moonekera bwino kuposa kuwala chifukwa cha kutalika kwa mafunde ake poyerekeza ndi kuwala kooneka. Ngakhale kuti phokoso ndi kuwala zonse zimawonetsa kusinthasintha, mafunde afupiafupi a kuwala kooneka amatanthauza kuti zotsatira zake za kusinthasintha sizimaonekera kwambiri m'zochitika za tsiku ndi tsiku.
6. Kodi liwiro la mafunde opingasa ndi a longitudinal mu medium imodzi limafanana bwanji?
   • yankho: Kuthamanga kwa mafunde opingasa ndi a longitudinal mu medium imodzi kungakhale kosiyana. Mwachitsanzo, mu zolimba, liwiro la longitudinal (P-wave) nthawi zambiri limakhala lachangu kuposa la transverse (S-wave).
7. Kodi sing'anga ikhoza kuwonetsa kayendedwe ka mafunde opingasa komanso otalika nthawi imodzi?
   • yankhoInde, kusokonezeka kwina kungapangitse mafunde opingasa ndi aatali mu sing'anga nthawi imodzi. Mwachitsanzo, zivomerezi zimapanga mafunde a P (longitudinal) ndi S (transverse) omwe amayenda padziko lapansi.
8. Ndi mtundu wanji wa mafunde womwe ungapangitse kuti pakhale kusiyana kwa mafunde pakafalikira?
   • yankhoMafunde ozungulira amatha kugawidwa m'magulu. Kugawidwa m'magulu kumaphatikizapo kuchepetsa kugwedezeka kwa mpweya ku gawo limodzi. Mafunde akutali, chifukwa cha kuyenda kwawo kumbuyo ndi kutsogolo, sangagawanitsidwe motere.
9. Kodi mafunde a electromagnetic ndi amtundu wanji, monga kuwala kapena mafunde a wailesi?
   • yankho: Mafunde amagetsi ndi mafunde opingasa. Mphamvu zawo zamagetsi ndi zamaginito zimasinthasintha molunjika komwe mafunde amafalikira.
10. N’chifukwa chiyani mafunde a S (mtundu wa mafunde opingasa) sawonedwa kuti akuyenda pakati pa dziko lapansi panthawi ya zivomerezi?

• yankhoMafunde a S samayenda pakati pa Dziko Lapansi chifukwa amakhulupirira kuti ndi amadzimadzi. Mafunde ozungulira amafuna njira yothandizira kupsinjika kwa mpweya, komwe zinthu zolimba zimatha, koma madzimadzi (zamadzimadzi ndi mpweya) sizingayende.
