Hi there!
Gravity from the sun is even and makes a planet orbit the sun by exerting a force that pulls the planet towards it. Since the gravity of the sun is always the same (or very, very similar), the planet's orbit stays the same.
Hope this helps!
Answer:
Partial pressure O₂ = 1.78 atm
Explanation:
We can apply the mole fraction to solve the question:
Moles of gas / Total moles = Partial pressure of gas / Total pressure
Total moles = 1 H₂ + 2.5 He + 2O₂ = 4.5 moles
2 mol O₂ / 4.5 mol = Partial pressure O₂ / 4 atm
(2 mol O₂ / 4.5 mol ) . 4 atm = Partial pressure O₂ → 1.78 atm

Answer:
Explanation: Rotation is when the Earth spins on it's axis and that's how there's 24 hours in one day to complete a rotation. Revolution is when the Earth re-volutes itself around the Sun. At the end of each year the Earth makes a complete revolution around the Sun. This is also the same for the moon revolting around Earth, making it day and night.
