Answer:
It is caused by air molecules colliding with smoke particles
Explanation:
To start with, Brownian motion is the erratic or irregular movement of very small particles in a medium due to continuous bombardment by molecules that surround the medium.
Thus, smoke moves in a Zig-Zag manner (Brownian motion) due to continious air bombardment. If it were pollen grain suspended in water, the erratic movement (Brownian motion) of the grains is caused by bombardment from water molecules.

What??? maybe not keep doing what you are doing.

I don't know
Answer:
n₁ > n₂.
prisms are made of glass with refractive index n₂ = 1.50, so the fluid that surrounds the prism must have an index n₁> 1.50
Explanation:
Total internal reflection occurs when the refractive index of the incident medium the light is greater than the medium to which the light is refracted, let's use the refraction equation
n₁ sin θ₁ = n₂ sin θ₂
the incident medium is 1, at the limit point where refraction occurs is when the angle in the refracted medium is 90º, so sin θ₂ = 1
n₁ sin θ₁ = n₂
sin θ₁ = n₂ / n₁
We mean that this equation is defined only for n₁ > n₂.
In our case, for the total internal reflection to occur, the refractive incidence of the medium must be greater than the index of refraction of the prism.
In general, prisms are made of glass with refractive index n₂ = 1.50, so the fluid that surrounds the prism must have an index n₁> 1.50
Answer:
no it can not effect the speed of sound not shure tho
Answer A is correct - m1l
