According to Bohr, the electrons in an atom were only allowed to exist at certain energy levels. ... Just as children cannot hover between two steps on a staircase, Bohr suggested that electrons cannot hover between two energy levels in the atom. Bohr developed his energy level model further using principles from physic
So really you only need to answer the first one because you have more than enough og everything. 2×(what)=14 then that will be your answer
This equation is balanced
Answer:
Speed, 
Explanation:
The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.
Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.
The work done by the particles is equal to the kinetic energy stored in it such that,

v is the speed with which the particles enter the cyclotron
So,

So, the speed with which the particles enter the cyclotron is
. Hence, this is the required solution.
I think it’s a baller for you and your
