Tsananguro yeDzidziso yaEinstein yeRelativity Dzidziso dzaAlbert Einstein dzeRelativity, dzinosanganisira Special Theory of Relativity (1905) uye General Theory of Relativity (1915), dzakachinja kunzwisisa kwedu nzvimbo, nguva, uye simba rinokwevera pasi. Dzidziso idzi idzo dzinokosha mufizikisi yemazuva ano, dzichipesvedzera nzvimbo dzakasiyana-siyana kubva kucosmology kusvika kuquantum mechanics. Muchinyorwa chino, tinoongorora hwaro hwedzidziso idzi, … Read more
# Mienzaniso Yematambudziko Ekufamba Kwakafanana Kwemutsara Kufamba kwakafanana kwemutsara, kunozivikanwawo sekufamba kwakafanana kwemutsara, zvinoreva kufamba kwechinhu nekumhanya kwakafanana munzira yakatwasuka. Rudzi urwu rwekufamba runoratidzwa nekumhanya kwakafanana, zvichireva kuti hapana kukurumidza. Muminda yakasiyana-siyana yakadai sefizikisi, mainjiniya, uye zuva nezuva … Read more
Kunzwisisa Mutemo wekutanga waNewton Mipiro yaSir Isaac Newton kusainzi yaive inoshamisa, uye Mutemo wake wekutanga wekufamba, unowanzonzi Mutemo wekusagadzikana, unomira seimwe yenheyo dzakakosha mufizikisi. Mutemo uyu unosimbisa hwaro hwemakanika ekare uye unotibatsira kunzwisisa maitiro ezvinhu zviri kufamba kana … Read more
Mibvunzo mitatu pamusoro peGravity equation
1. Zvidimbu zvitatu chimwe nechimwe chine huremu hwe1 kg zviri pamucheto wetriangle yakaenzana ine mativi akareba mita imwe. Simba regiravhiti rinowanikwa nechikamu chimwe nechimwe (muG) rakakura sei?
mhinduro
Hukuru hwesimba rinokwevera pasi rinoonekwa nechimwe chezvikamu.
F12 = G (m1)(m)2) / r2 = G (1)(1) / 12 = G/1 = G
F13 = G (m1)(m)3) / r2 = G (1)(1) / 12 = G/1 = G
Simba rinokwevera pasi rinobuda pachikamu chekutanga:
Mibvunzo mitatu pamusoro peElectric field equations
1. Bhora rinofambisa bhora rine radius ye10 cm rine chaji yemagetsi ye500 μC. Mapoinzi A, B, naC ari pamutsara nepakati pebhora ari chinhambwe che12 cm, 10 cm uye 8 cm zvichiteerana kubva pakati pebhora. Verenga simba remagetsi papoinzi A, B, naC!
Inozivikanwa:
Radiyo yebhora rinofambisa (R) = 10 cm = 0.1 m
Chaja yemagetsi (q) = 500 μC = 500 x 10-6 C
rA = 12 masendimita = 0,12 m
rB = 10 masendimita = 0,1 m
rC = 8 masendimita = 0,08 m
Chikamu cheCoulomb (k) = 9 x 109
Kuda: Simba remagetsi panzvimbo A (E)A), panzvimbo B (EB) uye padanho C (EC)
Solution:
Mibvunzo mitatu nezve equation yenguva dzose yechirimo
1. Chitubu chiri mu free suspension chine urefu hwe 10 cm. Pamucheto wakasununguka, huremu hwe 200 gram hunosungirirwa kuitira kuti hurefu hwe spring huve 11 cm. Kana g = 10 m/s2, chii chinonzi simba rechitubu risingaperi?
Anozivikanwa:
Kureba kwekutanga kwechitubu (y1) = 10 cm = 0.10 m
Kureba kwekupedzisira kwechitubu (y2) = 11 cm = 0.11 m
Kuchinja kwehurefu hwechitubu (Δy) = 0.11 – 0.10 = 0.01 mamita
Huremu hwemutoro (m) = 200 magiramu = 0.2 kg
Kurema kwemutoro (w) = mg = (0,2)(10) = 2 Newtons
Kuda: Chimiro chenguva dzose chechirimo (k)
Solution:
