<span>In thermodynamics, the internal energy of a thermodynamic system, or a body with well-defined boundaries, denoted by U, or sometimes E, is the total of the kinetic energy due to the motion of molecules (translational, rotational, vibrational) and the potential energy associated with the vibrational and electric energy of atoms within molecules or crystals. It includes the energy in all the chemical bonds, and the energy of the free, conduction electrons in metals.</span>
The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
No if you pass the rest you will not have to retake the credit trust me i know
I think it’s The second option sorry if I’m wrong
