Answer:
The star-sphere discovered by the Greeks and other ancient civilizations which shows the physical location in space of the nearby stars.
Explanation:
The celestial sphere is an ideal sphere, without defined radius, concentric with the terrestrial globe, in which the stars apparently move. Some ancient civilizations such as the Greeks assumed that the stars were attached to a celestial sphere, which revolves around the earth, while our planet is always immobile.
Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. Explanation:
According to Charles law, we know, at constant pressure, volume is directly proportional to temperature.
So, V/T = constant
V₁/t₁ = V₂/t₂
V₁t₂ = V₂t₁
Here, we have: V₁ = 1.50 L
V₂ = 0.40 L
T₂ = 77.2 K
T₁ = ?
Substitute their values into the expression:
1.50 × 77.2 = 0.40 × T₁
T₁ = 115.8 / 0.40
T₁ = 289.5
After rounding-off to unit place value, it would be equal to 290 K
So, In short Option D would be your correct answer.
Hope this helps!
