Answer:-
In physics a law describes a natural phenomenon, but does not attempt to describe how it works.
Newton's law of gravitation describes the attractive force F between two bodies with masses m1 and m2, which are a distance r apart.
/r²
Where G is the gravitational constant.
This is a law because it describes the force but makes not attempt to explain how the force works.
A theory is an explanation of a natural phenomenon. Einstein's General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.
Einstein also produced an equation which describes gravity. It may look simple, but in reality it is very complex and very hard to solve.
Gμν=
So, we have both a law and a theory of gravity.
Answer: Electrons.
Explanation:
Electrons are the negatively charged particles that orbit the nucleus of an atom. Protons, on the other hand, are the positively charged particles that orbit the nucleus of an atom.
in the picture, the protons and neutrons are “in” the nucleus and you’ll also see the the electrons are orbiting all around the nucleus.
