The force acting on the bag is equal and opposite to the force acting on the fist.
The fist creates the action force and the punching bag creates the reaction force.
Idk but look it up on google
Answer:
The concentration of [A⁻] is 0,0166M
Explanation:
In the equilibrium of a weak acid:
HA ⇄ A⁻ + H⁺
The solution of a weak acid contains, initially, the concentration of HA is Y. In equilibrium, the concentrations of each compound are:
[HA] = Y-x
[A⁻] = x
[H⁺] = x
That means [H⁺] = [A⁻].
The pH is defined as -log₁₀ [H⁺]. As the pH was 1,78:
1,78 = -log₁₀ [H⁺]
0,0166M = [H⁺]
As [H⁺] = [A⁻], <em>the concentration of [A⁻] is 0,0166M</em>

From the calculation, the binding energy of the oxygen atom is 1.98 * 10^11 J
<h3>What is the binding energy?</h3>
The term binding energy has to do with the energy that must be supplied to the nucleus of an atom for the nucleus of the atoms to be bonded together.
We must note that;
E = mc^2
E = 2.20 × 10 -28 kg * ( 3 * 10^8m/s)^2 = 1.98 * 10^11 J
