If the two forces act in the same direction, their resultant is 13N .
If they act in opposite directions, their resultant is 3N .
These are the limits. The resultant is always between 3N and 13N.
So (B), (C), and (D) (3N, 10N, and 13N are possible.)
<em>(A)</em> 2N is not possible.

.Internal energy is the total potential and kinetic energies in a substance, and thermal energy is the part of internal energy that can be transferred to another substance. Thus, option "C" is correct.
<h3>What is the thermal energy Meaning?</h3>
Thermal energy, is internal energy present in a system in a form of thermodynamic equilibrium probity by its temperature.
Thermal energy cannot be transformed to useful work as easily as the energy of systems that are not in conditions of thermodynamic equilibrium.
Thus, option "C" is correct
