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.
It should be the B
Low frequency and long wavelength
I personally would live on Mars cuz that is red cuz
The work of Brian mind interface is to learn that’s my guess lol
Answer:
The correct option is;
Still constant
Explanation:
The relative refractive index ₁n₂ between the two medium can be as follows;
Therefore, given that the speed of light in medium 1 is constant and the speed of light on medium 2 is also constant, the relative refractive index ₁n₂ = c₁/c₂ is always constant.
