"It acts over a very small distance" would be the best answer as to a characteristic of the strong nuclear force, since its primary purpose is to bind the smallest particles together.
The change in the internal energy of the system is 110 kJ.
<h3>What is internal energy?</h3>
Internal energy is defined as the energy associated with the random, disorder motions of molecules.
calculate the change in internal energy, we apply the formula below.
Formula:
- ΔU = Q-W.................... Equation 1
Where:
- ΔU = Change in internal energy
- Q = Heat absorbed from the surroundings
- W = work done by the system
From the question,
Given:
Substitute these values into equation 1
Hence, The change in the internal energy of the system is 110 kJ.

I believe it would be x because you are trying to find the width of the wave but i could be wrong
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound.
<h3>What is the Avogadro’s number?</h3>
The Avogadro’s number is used to represent the number of elementary entities that exist in one mole of a compound. The numerical value of the Avogadro’s number is obtained as 6.02 x 10^23 and consists of the atoms, molecules and ions in the compound.
The scientist Josef Loschmidt strengthened the Avogadro’s number by obtaining the number of particles in one cubic centimeter of gas under standard conditions.

To solve this problem we will apply the concepts of Boiling Point elevation and Freezing Point Depression. The mathematical expression that allows us to find the temperature range in which these phenomena occur is given by
Boiling Point Elevation
Here,
= Constant ( Different for each solvent)
m = Molality
Freezing Point Depression
Here,
Constant ( Different for each solvent)
m = Molality
According to the statement we have that
From the two previous relation we can find the ratio between them, therefore
We already know the change in the freezing point, then
The temperature difference in the boiling point is 100°C (Aqueous solution), therefore
Therefore the boiling point of an aqueous solution is
