The correct answer for the given question above would be option C. ULTRAVIOLET RAYS. The electromagnetic wave that can permanently damage the skin is the ultraviolet waves. Ultraviolet or UV waves <span>can interact with your skin and your eyes. This is usually the main cause in the skin color changes, and acquiring skin cancer. Hope this answer helps.</span>
The top of the wavelength is called the crest.
No, there were other scientists who developed the cell theory with him.
If there are no dissipative forces acting on the string, than the <em>principle of conservation of energy</em> holds.
When the string is relaxed, it has zero elastic potential energy
If we were strech the she spring, we would increase it's potential energy. After releasing the spring, when it's relaxed again, all potential energy will have been converted into kinetic energy.
Therefore, the elastic potential energy of the stretched spring should be equal to the amount of kinetic energy when it's relaxed
