Answer:
Because the moon rotates as it revolves around the Earth, we only ever see on side of the moon (That is why we call the other side the "dark side of the moon").

Answer:
root mean square velocity of nitrogen at 25°c is 515 m/s
correct option is b) 515 m/s
Explanation:
given data
temperature = 25°c = 25 + 273 = 298 K
to find out
root mean square velocity of nitrogen molecules
solution
we know that root mean square velocity of gas is Vrms = 
.......................1
mass of gas = M
universal gas constant = R
temperature = T
and we know mass of nitrogen = 28 g = 28 × 
kg
Vrms =
Vrms = 
Vrms = 515.22 m/s
root mean square velocity of nitrogen at 25°c is 515 m/s
correct option is b) 515 m/s
Answer:
C₄H₁₀(g) + O₂(g) ⇒ CO₂(g) + H₂O(g)
2 C₄H₁₀(g) + 13 O₂(g) ⇒ 8 CO₂(g) + 10 H₂O(g)
Explanation:
Butane gas (C₄H₁₀) burns in oxygen gas to produce carbon dioxide gas and water vapor. The unbalanced equation is:
C₄H₁₀(g) + O₂(g) ⇒ CO₂(g) + H₂O(g)
First, we will balance carbon and hydrogen which are in just one compound on each side.
C₄H₁₀(g) + O₂(g) ⇒ 4 CO₂(g) + 5 H₂O(g)
Finally, we will balance the oxygen atoms.
C₄H₁₀(g) + 6.5 O₂(g) ⇒ 4 CO₂(g) + 5 H₂O(g)
In order to have integers, we will multiply everý compound by 2.
2 C₄H₁₀(g) + 13 O₂(g) ⇒ 8 CO₂(g) + 10 H₂O(g)
Answer:
The correct answer is sedimentary rock.
Explanation:
The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.

Key Points
Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release.
During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
