Answer:
Diamond
Explanation:
As light moves from a less dense medium to a denser medium it slows down.
This is because the wave length of the light reduces. The denser the medium the less the wavelength. Diamond is the most dense solid among the provided choices thus light travelling through it has the least wavelength.

Answer:
one kilogram is the answer
It is more energetically stable to do that. Nature prefers to have a low energy state. If you go somewhere in nature you will usually find a low energy state object or material.
Answer:
Option A. It has stayed the same.
Explanation:
To answer the question given above, we assumed:
Initial volume (V₁) = V
Initial temperature (T₁) = T
Initial pressure (P₁) = P
From the question given above, the following data were:
Final volume (V₂) = 2V
Final temperature (T₂) = 2T
Final pressure (P₂) =?
The final pressure of the gas can be obtained as follow:
P₁V₁/T₁ = P₂V₂/T₂
PV/T = P₂ × 2V / 2T
Cross multiply
P₂ × 2V × T = PV × 2T
Divide both side by 2V × T
P₂ = PV × 2T / 2V × T
P₂ = P
Thus, the final pressure is the same as the initial pressure.
Option A gives the correct answer to the question.
