4 Ọrụ Net Ike ike ndọda Ike Kinetic - Nsogbu na Ngwọta

1. Ihe dị kilogram ise n'ogo mita iri n'elu ala. Ọsọ ọsọ nke ike ndọda bụ mita iri n'ime awa ^abụọ . Gịnị ka a na- arụ n'ihe ahụ iji bulie ya elu ruo mita iri na ise n'elu ala?

A maara:

Ibu ihe (m) = 5 kg

Ogologo (h) = mita 10

Ọsọ ọsọ nke ike ndọda (g) = 10 m/s ²

Achọtara: E tinyere ọrụ n'ihe ahụ iji bulie ya elu ruo n'ogo nke mita iri na ise n'elu ala.

1. Nrụgide ikuku nke taya ụgbọala bụ 432 kPa , okpomọkụ ya dịkwa 1 5 ^o C. Mgbe awa ole na ole gachara, nrụgide ikuku bụ 492 kPa. Ọ bụrụ na eleghara mmụba anya , kedu okpomọkụ ikuku dị na taya ahụ?

A maara:

Nrụgide mbụ (P1 ₎ = 432 kPa

Nrụgide ikpeazụ (P2 ₎ = 492 kPa

Okpomọkụ mbụ ( T ₁ ) = 15 ^oC

Achọrọ: Okpomọkụ ikpeazụ ( _T2 )

Manometer tube - nsogbu na ngwọta

1. A na-ejupụta ọkpọkọ manometer na ụdị mmiri abụọ. Njupụta nke mmiri 1 bụ ρ ₁ = 0.8 g.cm ^-3 , njupụta nke mmiri 2 bụkwa ρ ₂ = 1 g.cm ^-3 , na elu h ₁ = 10 cm, kedu ka elu h ₂ dị?

A maara:

Njupụta nke mmiri mmiri 1 = 0.8 g.cm ^-3

Njupụta nke mmiri mmiri 2 = 1 g.cm ^-3

Ogologo 1 = 10 cm

Achọrọ: Ogologo nke abụọ
