Answer:
breaking apart of atoms of certain elements to release rays of energy or particles.
Atoms are the building blocks of elements. However, some atoms have an excessive number of neutrons or protons in their nuclei. This causes an imbalance in the forces that keep them together, resulting in an excessive amount of internal energy. These atoms are referred to as radioactive or unstable.
hope this is helpful...
It can be purified or be used by a filter
Answer:
Explanation:
Two
The nuclear force does not work
under long distances
is greater in strength the the electomagnetic force when the distances are small.
I'm not sure what D means.
I think it does depend on charge.
You have to choose D but this is a notes question and I'm not at all certain of the answer.
One
If its number is 19, the the number of protons = the number of electrons = 19
Answer B
<h2>
Magnitude of force doubles.</h2>
Explanation:
Force between two charges is given by
where q₁ and q₂ are charges and r is the distance between them.
Here one charge is doubled with keeping all others same.
q₁ = 2 q₁
We have
Magnitude of force doubles.
