Answer:
Let N = N0 where N0 is the number of atoms originally present.
In 6 days N = N0 / 2
In 12 days N = N0 / 4
In 18 days N = N0 / 8 = .125 N0
So it would take 18 days.

The electric potential energy of the electron depends on the potential difference applied between the two ends of the cable. Indeed, the electric potential energy of a charge is given by
where q is the magnitude of the charge, while
is the potential difference applied. So, U depends on
.
Answer:
number of Protons=16
number of Neutrons=16
number of electrons=32
Explanation:
Tip:-
<em><u>Always the number of protons = the number of neutrons.</u></em>
<em><u>Add them and you will get the number of electrons.</u></em>

Newton's new “reflecting telescope” was more powerful than ... Before Newton, scientists primarily adhered to ancient theories on ... laws of motion laid the groundwork for classical mechanics. Newton's research on motion helped give credibility to the heliocentric view. Newton also helped pioneer telescopic innovations, and he is sometimes credited with inventing the first reflecting telescope. He also conducted experiments using the prism, and developed a theory about the nature of color and light.
