The key to answering this question is to realize that you have two polyhedrons combined to form one thus the overall volume would be equal to the sum of the two polyhedron.
Total volume= (volume of prism) + (volume of cuboid)
a) Volume of cuboid (
)=
l = 13ft
w = 18ft
h = 21ft
: . <span>
= 13ft * 18 ft * 21ft
</span> = 4914
b) Volume of Prism (<span>
)</span> =
b = 18ft
h = 16ft
H = 13ft
: .
=
= 1872
Thus Overall Volume = 6786
The elements heavier than hydrogen and helium were produced inside stars.
During most of a star's lifetime, hydrogen nuclei fuse together to form helium nuclei.As the star runs out of hydrogen, other elements. Heavier elements than hydrogen and helium are form. Elements heavier than iron are formed in supernovas.
Answer:
they have same number of electrons
Answer:
Result of the formation of positive and negative ions.
