The Correct answer is (B), Because the reject each other.
Elastic potential = 1/2 x constant x square of compression lenght
So it's 360 N/m
The products should she record in the last row of the table : <u>2LiCl + 3O₂</u>
<h3>Further explanation</h3>
There are several chemical reactions, namely:
-
Formation reaction
-
Decomposition reaction.
- Replacement reaction.
-
Multiple replacement reactions
-
Neutralization reaction.
-
Combustion reaction.
-
Polymerization
The decomposition reaction in a chemical reaction shows the decomposition reaction of a compound into its constituent elements or compounds
Rosa recorded three similar decomposition reactions
Reactions that occur :
1. 2 NaClO₃ ⇒ 2NaCl + 3O₂
2. 2KClO₃ ⇒ 2KCl + 3O₂
3. 2LiClO₃ ⇒ 2LiCl + 3O₂
There are similarities in the decomposition that forms oxygen and chloride compounds

Mathematically it can be expressed as: I = FpΔt. Where F p is the average magnitude of the acting force and Δt = t 2 - t 1, the time lapse in the force acts.
The magnitude of the impulse applied to stop the cart is
I = FpΔt = (10N) * (5s) = 50 N.s
Answer:
60.8 cm²
Explanation:
The charge density, σ on the surface is σ = Q/A where q = charge = 87.6 pC = 87.6 × 10⁻¹² C and A = area = 65.2 cm² = 65.2 × 10⁻⁴ m².
σ = Q/A = 87.6 × 10⁻¹² C/65.2 × 10⁻⁴ m² = 1.34 × 10⁻⁸ C/m²
Now, the charge through the Gaussian surface is q = σA' where A' is the charge in the Gaussian surface.
Since the flux, Ф = 9.20 Nm²/C and Ф = q/ε₀ for a closed Gaussian surface
So, q = ε₀Ф = σA'
ε₀Ф = σA'
making A' the area of the Gaussian surface the subject of the formula, we have
A' = ε₀Ф/σ
A' = 8.854 × 10⁻¹² F/m × 9.20 Nm²/C ÷ 1.34 × 10⁻⁸ C/m²
A' = 81.4568/1.34 × 10⁻⁴ m²
A' = 60.79 × 10⁻⁴ m²
A' ≅ 60.8 cm²
