Misalai 4 na Tambayoyin Pendulum Masu Sauƙi Pendulum Mai Sauƙi

1. Layin layi mai sauƙi ya ƙunshi igiya mai tsawon santimita 40 kuma an rataye nauyin gram 100 a ƙarshen layin. Idan saurin gudu saboda nauyi ya kai mita 10/s² Don haka lokaci da mita na pendulum mai sauƙi sune...
Tattaunawa
An sani :
Tsawon igiya (l) = 40 cm = mita 0,4
Saurin gudu saboda nauyi (g) = 10 m/s²
An tambaya : Lokaci (T) da mita (f)
Jawab :
Tsarin lokaci mai sauƙi na pendulum :
Bayani: T = lokaci, l = tsawon igiya, g = hanzari saboda nauyi
Lokacin wani ƙaramin pendulum :
Mitar Pendulum mai sauƙi :
Hanya ta 1:
f = 1/T = 1/1,256 = 0,8 Hertz
Hanya ta 2:
2. Lissafa tsawon igiyar da ke kan agogon pendulum wanda ke bugawa sau ɗaya a cikin daƙiƙa ɗaya.
Tattaunawa
An sani :
Lokaci (T) = daƙiƙa 1
Saurin gudu saboda nauyi (g) = 10 m/s²
An tambaya Tsawon waya (l)
Jawab :
Tsarin lokacin kirtani :
Tsawon igiya :
3. Pendulum mai sauƙi yana da igiya mai tsawon santimita 50 da nauyin gram 50. Mafi girman wurin nauyin shine santimita 10 sama da mafi ƙasƙancin wurin. Idan saurin gudu saboda nauyi shine mita 10/s², ƙayyade (a) lokaci da mita na pendulum (b) saurin kaya a mafi ƙasƙanci wuri.
Tattaunawa
An sani :
Tsawon igiya (l) = 90 cm = mita 0,9
Saurin gudu saboda nauyi (g) = 10 m/s²
Canjin tsayi (h) = 20 cm = mita 0,2
An tambaya : (a) T da f (b) v
Jawab :
(A) Lokaci (T) da mita (f) na ƙaramin pendulum
lokaci
Mita:
f = 1/T = 1/1,884 = 0,53 Hertz.
(B) Saurin (v) na kayan a mafi ƙanƙantarsa
Wannan tambayar tana da alaƙa da dokar kiyaye makamashin inji.
A mafi girman matsayi, nauyin yana da ƙarfin ƙarfin nauyi mafi girma kuma babu kuzarin motsi saboda yana tsayawa na ɗan lokaci lokacin da yake juyawa alkibla. Yayin da nauyin ya fara motsawa ƙasa, ƙarfin ƙarfin nauyi yana canzawa zuwa kuzarin motsi. A mafi ƙanƙantar matsayi, duk ƙarfin ƙarfin nauyi yana canzawa zuwa kuzarin motsi. Saboda haka, a mafi ƙanƙantar matsayi, ƙarfin motsin nauyi yana kan iyakarsa kuma ƙarfin ƙarfin ƙarfinsa sifili ne.
Makamashin injina na farko = makamashin ƙarfin nauyi = mgh
Makamashin injiniya na ƙarshe = makamashin motsi = ½ mv²
Dokar kiyaye makamashin inji :
Makamashin injina na farko = makamashin injina na ƙarshe
Makamashin ƙarfin nauyi = makamashin motsi
mgh = ½ mv²
2 gh = v²
(2)(10)(0,2) = v²
4 = ku²
v = 2m/s

4. Agogon bango a saman Duniya yana aiki ta hanyar amfani da motsin pendulum mai juyawa. Idan an ɗauki agogon a tashar sararin samaniya kuma an yi nisa da abubuwan sararin samaniya, to...

A. Hannun agogo suna motsawa da sauri

B. hannayen agogo ba sa motsawa

C. Agogon yana aiki daidai

D. pendulum yana juyawa a hankali

E. pendulum yana juyawa a ƙasan mita

Tattaunawa

A saman duniya, pendulum na iya motsawa saboda kasancewar ƙarfin nauyi Duniya tana aiki a kan pendulum. Sabanin haka, a sararin samaniya, ƙarfin nauyi da ke haifar da shi ya kusa kusan sifili, don haka hannayen agogo ba sa motsawa.
