I'd say it's A because while the energy cannot be lost, it can not be 100% efficient because if it was we wouldn't have to worry about energy.
Explanation:
In a magnetic field, the radius of the charged particle is as follows.
r =
where, m = mass, v = velocity
q = charge, B = magnetic field
Therefore, q will be calculated as follows.
q =
=
=
=
= +2e
Thus, we can conclude that the charge of the ionized atom is +2e.
Answer:
Molecules vibrate in a fixed position.
Explanation:
first one is just wrong.
third is liquid
fourth is gas
Answer:
billion is larger \ part if billion
It required a fixed finite amount these zones are known as energy levels
