You did not specify the types, but I believe the answer would be gamma radiation.
Answer:
Hello there! How are you doing today :] Sand would be a covalent bond.
Explanation:
Silica is one of the main compounds found in sand. It also contains many silicon and oxygen atoms. which; are joined together by covalent bonds in a regular arrangement, forming a giant covalent structure.
Answer: An atom in an excited state contains more of kinetic energy than the same atom in the ground state.
Explanation:
Kinetic energy is the energy acquired by an object due to its motion. And, thermal energy is the internal energy of an object arisen because of the kinetic energy present within the molecules of the object.
Potential energy is the energy acquired by an object due to its position.
The total energy present at the center of mass of an object is known as mass-energy.
So, when an atom gets excited then it means it is gaining kinetic energy due to which it moves from its initial position after getting excited.
Thus, we can conclude that an atom in an excited state contains more of kinetic energy than the same atom in the ground state.
I would say the answer is A.
