Answer: Option (a) is the correct answer.
Explanation:
When rain passes through the air then carbon dioxide present in the air dissolves in the water. Further, this carbon dioxide reacts with water and results in the formation of carbonic acid.
Thus, the rain water becomes acidic in nature and as a result, there will be decrease in its pH.
Hence, we can conclude that rain has a natural pH that is acidic.

Isn't velocity Distance over time? if the degree isn't adding resistance it should be 4000 ÷ 20 which gives you 200mps ("per second") which is the velocity without resistance.
Answer:
43.83 nC
Explanation:
We know Q = ε₀Ψ where Q = charge enclosed by the cubic box, ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m and Ψ = net electric flux through cubic box = 4950 Nm²/C
So, substituting the values of the variables into the equation, we have
Q = ε₀Ψ
= 8.854 × 10⁻¹² F/m × 4950 Nm²/C
= 43827.3 × 10⁻¹² C = 4.38273 × 10⁻⁸ C
= 43.8273 × 10⁻⁹ C
= 43.8273 nC
≅ 43.83 nC
