Answer:
Explanation:
The kinetic energy of an object is given by 
where 
is the mass of the object and 
is the velocity of the object.
We can set up the following equations with the information given:
For part B, we have the same equation, but kinetic energy is now 
.
Therefore:
.
They don't require a medium to propagate, meaning that they can travel through air, solid objects, and space.
Answer:
B) Electrons and protons
Explanation:
Each proton has a positive charge, and each electron has a negative charge. If the atom is electrically neutral, there must be the same number of electrons and protons.
A) and C) are wrong. Neutrons have no charge, so they can't counteract that of the protons or the electrons.
D) is wrong. The atomic number is the number of protons, and the mass number is the number of protons plus neutrons. The neutrons can't counteract the charge of the protons,
.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
