Nā pilikia i hoʻoponopono ʻia ma ke ʻano Physics kumu

Ka manawa o ka inertia no nā ʻāpana - nā pilikia a me nā hoʻonā

1. ʻElua mau pōpō i hoʻopili ʻia e kahi koʻokoʻo, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei. E hoʻowahāwahā i nā koʻokoʻo nuipa. ʻO ke kaumaha o ka pōpō P he 600 grams a ʻo ke kaumaha o ka pōpō Q he 400 grams. He aha ka manawa o ka inertia o ka ʻōnaehana e pili ana iā AB?

ʻIke ʻia:

ʻO ke axis o ka wili ʻo AB.

m_p = 600 grams = 0.6 kg, m_q = 400 grams = 0.4 kg

r_p = 20 kenimika = 0.2 m, r_q = 50 kenimika = 0.5 mika

Makemake ʻia: ʻO ka manawa o ka inertia o ka ʻōnaehana

4 Hana Upena Ikehu hiki ke hoʻopaʻa ʻia Ikehu kinetic - Nā pilikia a me nā hoʻonā

1. He mea 5-kg ma ke kiʻekiʻe o 10-mika ma luna o ka honua. ʻO ka wikiwiki ma muli o ka umekaumaha he 10 m/s²He aha ka hana i hana ʻia ma luna o ka mea e hoʻoneʻe iā ia i luna a hiki i ke kiʻekiʻe o 15 mika ma luna o ka honua?

ʻIke ʻia:

Ka Mass o ka mea (m) = 5 kg

Kiʻekiʻe (h) = 10 mika

Ka wikiwiki ma muli o ke koʻikoʻi (g) = 10 m/s²

Makemake: Ua hana ʻia ka hana ma luna o ka mea e hoʻoneʻe iā ia i luna i ke kiʻekiʻe o 15 mika ma luna o ka honua.

Ka manawa o ka ikaika - nā pilikia a me nā hoʻonā

1. Inā ʻo F_R ʻo ia ka ikaika upena o F₁, F₂, a me F₃, he aha ka nui o ka ikaika F₂ a me x?

ʻIke ʻia:

Ka ikaika ʻupena (F_R) = 40 N

Ikaika 1 (F₁) = 10 N

Ikaika (F₃) = 20 N

Makemake: Ka nui o ka ikaika F₂ a me ka mamao o x

14 Ke kānāwai o Boyle Ke kānāwai o Charles Ke kānāwai o Gay-Lussac - Nā pilikia a me nā hoʻonā

1. ʻO ke kaomi ea o nā huila o ke kaʻa 432 kPa me ka mahana o 15 ^oC. Ma hope o kekahi mau hola, ua kaomi o ka ea 492 kPa. Inā hoʻowahāwahā ʻia ka hoʻonui ʻana, he aha ka wela o ka ea i loko o ka huila?

ʻIke ʻia:

Kaomi mua (P₁) = 432 kPa

Pumi hope (P₂) = 492 kPa

Mahana mua (T₁) = 15 ^oC

Makemake: Mahana hope loa (T₂)

Kaʻapuni Carnot - nā pilikia a me nā hoʻonā

1. Inā wela i omo ʻia e ka ʻenekini (Q₁) = 10,000 Joules, he aha ka hana i hana ʻia e ka ʻenekini Carnot?

ʻIke ʻia:

Haʻahaʻa ka mahana (T₂) = 400 K

Mahana kiʻekiʻe (T₁) = 800 K

Hoʻokomo wela (Q₁) = 10,000 Joule

Makemake: Hana i hana ʻia e ka ʻenekini Carnot (W)

ʻO ka paipu manometer - nā pilikia a me nā hoʻonā

1. A paipu manometer ua piha i ʻelua ʻano wai. ʻO ka nui o ka wai 1 ʻo ρ₁ = 0.8 g.cm^-3, a ʻo ka nui o ka wai 2 ʻo ρ₂ = 1 g.cm^-3, a me ke kiʻekiʻe h₁ = 10 kenimika, a laila he aha ke kiʻekiʻe o h₂.

ʻIke ʻia:

Ka nui o ka wai 1 = 0.8 g.cm^-3

Ka nui o ka wai 2 = 1 g.cm^-3

Kiʻekiʻe 1 = 10 kenimika

Makemake: Kiʻekiʻe 2

Ikehu mīkini - nā pilikia a me nā hoʻonā

ʻO ke kumumanaʻo hana-ikaika mechanical

1. ʻO ke koina o ka ka ʻūmiʻi kinetic ma waena o ka poloka a me ka papahele (μ_k) he 0.5. He aha ka ka haʻalele o kahi mea (mau mea)? ʻO ka wikiwiki ma muli o ka umekaumaha he 10 m/s².

ʻIke ʻia:

ʻO ke koina o ka friction kinetic (μ_k) = 0.5

Ka Mass o ka poloka (m) = 4 kg

ʻO ka wikiwiki ma muli o ke kaumaha (g) he 10 m/s²

Ka mahana a me ka wela - nā pilikia a me nā hoʻonā

1. Ma kahi ana wela X, ke kiko hau o ka wai ma -30^o a me ke kiko paila o ka wai ma 90^o. 60^OX = ….. ^oC.

ʻIke ʻia:

ʻO ke kiko hau o ka wai = -30^o

Ka paila ʻana o ka wai = 90^o

Makemake ʻia: 60^oX = ….. ^oC
