Answer:
Yes, why has been explained
Explanation:
Yes, Fusion takes place in the atmosphere of stars. Mostly stars are composed of hydrogen and helium, small quantity of other heavier elements.
The stars get their energy by the fusion reaction that continuously takes place inside them. The fusion of two hydrogen molecules to form a helium molecule. This reaction generates enormous amount of heat and light, which why the stars are so shiny and hot.
The answer is C. I hope this helps you.
Answer:
The dimension is L
Explanation:
Dimension analysis is a method of representing quantities majorly with respect to some fundamental quantities of mass (M), length (L), time (T).
A sphere has a definite volume which relates to its radius by:
V = 
In this equation is a dimensionless quantity, and the unit of v is 
.
But, metre is a measure of length, thus it has a dimension of L.
So that,
≅ 
Then,
=
Find the cube root of both sides to have,
r = L
Therefore, the dimension of the radius of a sphere is L.
This group is called “noble gases” because they do not react with other elements. This is because they have a full valence shell.
