4 Umsebenzi we-Net Amandla adonsela phansi Amandla e-Kinetic - Izinkinga Nezixazululo

1. Into engamakhilogremu angu-5 ukuphakama kwamamitha ayi-10 ngaphezu komhlabathi. Ukusheshisa ngenxa yamandla adonsela phansi ingu-10 m/s². Kuyini umsebenzi kwenziwe entweni ukuze uyinyuse iye phezulu ifike kumamitha ayi-15 ngaphezu komhlabathi?

Kwaziwa:

Imisa kwento (m) = 5 kg

Ukuphakama (h) = amamitha angu-10

Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s²

Okufunayo: Kwenziwe umsebenzi kule nto ukuze inyuswe iye phezulu ifike endaweni ephakeme ngamamitha ayi-15 ngaphezu komhlabathi.

14 Umthetho kaBoyle Umthetho kaCharles Umthetho kaGay-Lussac – Izinkinga Nezixazululo

1. Umfutho womoya wamathayi emoto uphansi kakhulu I-432 kPa ngezinga lokushisa elingu-15 ^oC. Ngemva kwamahora amaningana, ingcindezi umoya 492 kPa. Uma ukunwetshwa kunganakwa, Yini lokushisa umoya osethayini?

Kwaziwa:

Ingcindezi yokuqala (P₁) = 432 kPa

Ingcindezi yokugcina (P₂) = 492 kPa

Izinga lokushisa lokuqala (T₁= = 15 ^oC

Okufunayo: Izinga lokushisa lokugcina (T)₂)

Umjikelezo we-Carnot - izinkinga nezixazululo

1 Uma ukushisa imuncwa yinjini (Q)₁) = 10,000 Joules, yimuphi umsebenzi owenziwe yi- Injini ye-Carnot?

Kwaziwa:

Izinga lokushisa eliphansi (T)₂) = 400 K

Izinga lokushisa eliphezulu (T)₁) = 800 K

Okokufaka ukushisa (Q)₁) = amaJoules ayi-10,000

Okufunayo: Umsebenzi owenziwe yinjini yeCarnot (W)

Ishubhu le-Manometer - izinkinga nezixazululo

I-1. A ishubhu le-manometer igcwele izinhlobo ezimbili zoketshezi. Ubuningi koketshezi 1 kungu-ρ₁ = 0.8 g.cm^-3, futhi ubuningi boketshezi 2 bungu-ρ₂ = 1 g.cm^-3, kanye nokuphakama h₁ = 10 cm, bese kuba ukuphakama kuka-h₂.

Kwaziwa:

Ubuningi boketshezi 1 = 0.8 g.cm^-3

Ubuningi boketshezi 2 = 1 g.cm^-3

Ukuphakama 1 = 10 cm

Okufunayo: Ukuphakama 2
