Answer:
E = 1.25×10¹³ N/m²
Explanation:
Young's modulus is defined as:
E = stress / strain
E = (F / A) / (dL / L)
E = (F L) / (A dL)
Given:
F = 10 kg × 9.8 m/s² = 98 N
L = 1 m
dL = 10⁻⁵ m
A = π/4 (0.001 m)² = 7.85×10⁻⁷ m²
Solve:
E = (98 N × 1 m) / (7.85×10⁻⁷ m² × 10⁻⁵ m)
E = 1.25×10¹³ N/m²
Round as needed.
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

Answer:
$ 18.75
Explanation:
given,
capacity of the Dave’s car = 12 gallons
Assuming that the tank is 3/8 full before
Cost of gas per gallon = $2.50 per gallon of gas
Volume Dave have to fill
=
=
of full tank
=
volume Dave have to fill = 7.5 gallons
total money Dave spent
= 7.5 gallons x $2.50
= $ 18.75
Dave have to spend $ 18.75 to fill tank to it capacity.
