Answer:
Volume = 2m³
Explanation:
The pressure of a gas is inversely proportional to its volume when its temperature is constant.
P₁V₁ = P₂V₂
V₂ = (P₁V₁) / P₂
V₂ = (4atm x 0.5m³) / 1atm
V₂ = 2 m³
Given :
An object with a volume of 9 cm³ is completely submerged in the water.
To Find :
How much water is displaced by the object.
Solution :
According to Archimedes' principle, the amount of volume displaced of fluid when an object is fully and partially submerged into that is equal to the volume of the object below the surface of liquid.
Now, it is given that object is fully submerged into water.
Therefore, volume of water displaced by the object is 9 cm³.
Answer:
b. Icy objects that form a tail as they come close to the Sun
Explanation:
Acording to NASA comets are cosmic snowballs made out of frozen gases, rock and dust, they usually are the size of a small town and contain water and organic compounds due to the collisions with Earth and other planets. When its orbit brings it close to the sun, it heats up, spewding dust and gases forming a tail that streches away from the sun, they also have a glowing head that is larger than most planets.
<em>Considering this information we can conclude that the correct answer is b. Icy objects that form a tail as they come close to the Sun.</em>
