<h2>Magnitude of force doubles.</h2>

Explanation:

Force between two charges is given by

              F=k\frac{q_1q_2}{r^2}

where q₁ and q₂ are charges and r is the distance between them.

Here one charge is doubled with keeping all others same.

            q₁ = 2 q₁

We have

               F_1=k\frac{q_1q_2}{r^2}\\\\F_2=k\frac{2q_1q_2}{r^2}\\\\\frac{F_1}{F_2}=\frac{k\frac{q_1q_2}{r^2}}{k\frac{2q_1q_2}{r^2}}\\\\\frac{F_1}{F_2}=\frac{1}{2}\\\\F_2=2F_1

Magnitude of force doubles.

Carlos was camping and getting cold as the sun went down. He wanted to light a fire for warmth and light. However, he discovered
storchak [24]
1. The chemical reaction produced by Carlo's fire is exergonic because energy is "going out". As the reaction proceeds, entropy increases as the energy stored in the dry wood and leaves are used up as fuel to create the fire which produces low quality light and warmth.  

2. This reaction is a classic example of an exothermic reaction. Exothermic reactions are characterized with the presence of heat and light in the products. Combustion reactions are always exothermic in nature.

3. Catalyst are substances that are used to speed up reactions by lowering the activation requirement. Catalysts aren't consumed in the reaction and can still be chemically retrieved afterwards. In this situation, the leaves cannot be retrieved after the reaction ends. The leaves speed up the heating of the wood but it does not behave as a catalyst.
