Answer:
The bohr's model is the primitive model for the hydrogen atom, comparatively to the atom of valence shell. And it is derived from the hydrogen atom of the first approximation by using the quantum mechanics.
Basically, the model state that the electron revolved around in circular orbit in atom around the central nucleus. And it can be fixed in the circular orbit at the set of discrete distance at the nucleus.
Most of the time the towns get flooded and many people die and lose their homes and their jobs, businesses by the floods and the natural environment is destroyed ,air pollution is produced, the ecosystem could be disrupted and dams are known to fall over and dams are really expensive to build, The dams also cause geological damage, example earthquakes and spills happen.

Explanation:
Answer:
Gravitational Potential Energy
Explanation:
a ball is held rest at the top of hill
gravitational potential energy will store due to its height
it. and body will start move downward and its potential energy will convert into kinetic energy due to motion of body
at the ground level it will stop and potential energy will became zero and kinetic energy get convert into internal energy due to collisions
