kinetic energy into potential energy.
when the rocks go down it will be kinetic energy but when the rock reach the bottom of the hill it will be converted into potential energy.
Answer:

Explanation:
The Industrial Revolution impacted the environment. The world saw a major increase in population, which, along with an increase in living standards, led to the depletion of natural resources. The use of chemicals and fuel in factories resulted in increased air and waterpollution and an increased use of fossil fuels.
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes.
A rock is an aggregate of one or more minerals. It may also contain organic remains and mineraloids apart from regular mineral formations. Since rocks vary in their mineral and chemical composition, they are classified according to the process of their formation.

The wavelength of the light produced by the laser is determined by the Composition of the active medium
Explanation:
As stipulated by Bohr's theory, different atoms have different and unique absorption and emission spectra that can also be used to identify them. The electrons of the atoms when excited (the enter an inversion state), using specific photons of electromagnetic waves, they move up energy levels. When the electrons move back to their ground state, they release the same wavelength of photons. The photos then excite other atoms and the amplification continues. Therefore the lasing medium is the main determinant of the wavelength of the laser beam.
For example, the use of argon fluoride as an active medium produces lasers of 193 nm in wavelength and the use of nitrogen produces laser of
