Pendulum iri nyore - matambudziko nemhinduro

1. Mapendulum maviri ari nyore ari munzvimbo mbiri dzakasiyana. Kureba kwependulum yechipiri kwakapetwa ka0.4 kupfuura kureba kwependulum yekutanga, uye kukurumidza kwegiravhiti kunowanikwa nependulum yechipiri kwakapetwa ka0.9 kupfuura kukurumidza kwegiravhiti kunowanikwa nependulum yekutanga . Sarudza kuenzanisa kwehuwandu hwependulum yekutanga nependulum yechipiri.

A.///

B. 3/2

C. 4/9

D. 9/4

Zvinozivikanwa:

Kureba kwetambo yependulum yekutanga (l ₁ ) = 1

Kureba kwetambo yependulum yechipiri (l ₂ ) = 0.4 (l ₁ ) = 0.4 (1) = 0.4

Kukurumidza kukwira nekuda kwekukweva kwependulum yekutanga (g ₁ ) = 1

Kukurumidza kukwira nekuda kwekukweva kwependulum yechipiri (g ₂ ) = 0.9 (1) = 0.9

Zvinodiwa: Kuenzanisa kwehuwandu hwependulum yekutanga (f ₁ ) nependulum yechipiri (f ₂ )

Solution:

Kuenzanisa kwehuwandu hwependulum yekutanga (f ₁ ) nependulum yechipiri (f ₂ ):

Mhinduro chaiyo ndeinoti A.

2. Chinhu chinorembera kubva kumucheto wetambo yobva yaita kufamba kuri nyore kweharmonic ne frequency ye 0.5 Hertz. Kana kureba kwetambo kwakawedzerwa nekanenge kana kureba kwekutanga, saka sarudza nguva yekufamba kweharmonic.

Masekondi ¼

B. ½ sekondi

C. Masekondi maviri

D. Masekondi mana

Zvinozivikanwa:

Kuwanda kwependulum (f) = 0.5 Hz

Zvinodiwa: Sarudza nguva (T) yependulum kana kureba kwetambo (l) kuri kana kureba kwekutanga

Solution:

Nguva ye pendulum yekutanga:

Kureba kwekutanga kwetambo:

Kana kureba kwetambo kwakawedzerwa nekanenge kana kureba kwekutanga:

Ipapo nguva ye pendulum ndeiyi:

Nguva yekufamba ndeye masekondi mana.

3. Mapendulum maviri ane urefu hwakaenzana hwetambo yawo, asi huremu hwependulum yechipiri hwakapetwa kana kupfuura huremu hwependulum yekutanga. Kana f ₁ iri frequency yependulum yekutanga uye f ₂ iri frequency yependulum yechipiri, saka sarudza hukama huripo pakati pe f ₁ na f ₂.

A. f ₁ = f ₂

B. f ₁ = 2 f ₂

C. f ₂ = 2 f ₁

D. f ₁ = 4 f ₂

Solution:

Equation yehuwandu hwe pendulum iri nyore:

f = frequency, g = kukurumidza nekuda kwegiravhiti, l = kureba kwetambo

Zvichibva pamuenzaniso uri pamusoro apa, tinogona kugumisa kuti huremu hahukanganisi frequency ye simple pendulum.

Mhinduro chaiyo ndeinoti A.

4. Huwandu huri pazasi husingakanganisi nguva ye pendulum iri nyore ndehwekuti…..

A. kureba kwetambo nehuremu hwechinhu chacho

B. kureba kwetambo uye kukurumidza nekuda kwesimba regiravhiti

C. huremu hwechinhu uye kona yekutanga

D. kureba kwetambo uye kona yekutanga

Solution:

Kuenzanisa kwenguva ye pendulum iri nyore:

T = nguva, g = kukurumidza nekuda kwesimba rinokwevera pasi, l = kureba kwetambo

Zvichibva pafomura iri pamusoro apa, tinogona kugumisa kuti kureba kwetsvimbo ( l) uye kukurumidza kwegiravhiti (g) zvinokanganisa nguva yependulum iri nyore . Zvikasadaro, huremu hwechinhu nekona yekutanga hazvikanganisi nguva yependulum iri nyore m.

Mhinduro chaiyo ndeinoti C.

5. Tambo yependulum iri nyore yakagadzirwa nenylon. Pamugumo mumwe wetambo pane huremu hwemagiramu gumi uye kureba kwetambo kuri mita imwe. Kana frequency inogadzirwa iri kaviri kupfuura frequency yekutanga, saka kureba kwetambo kunofanirwa kuchinjwa kuita…

A. 0.25 mamita

B. 0.50 mamita

C. 2.0 mamita

D. 4.0 mamita

Zvinozivikanwa:

Huremu hahukanganisi kuwanda kwependulum iri nyore.

Kureba kwetambo yependulum iri nyore (l) = mita imwe

Zvinodiwa: sarudza kureba kwetambo kana frequency yacho yakapetwa kaviri kupfuura frequency yekutanga

Solution:

Kuwanda kwekutanga kwe pendulum iri nyore:

Kuwanda kwe pendulum iri nyore kunowedzera kaviri kupfuura kutanga kwayo:

Kuti frequency yekupedzisira ipetwe kaviri, kureba kwependulum kunofanira kuchinjwa kuita mamita 0.25.
