Answer:
Given that refractive index of the material is √2. i.e. n = √2. Hence, critical angle for the material is 45°
-- There is nothing on the list of choices that you provided that has no mass.
-- There are no "things" that have no mass. Every sample of a liquid, a gas,
or a solid has mass, even if it's only an atom or two.
I think the only possible items you could name that have no mass would be
spiritual, conceptual, or sensory ones, like maybe ...
-- idea
-- conviction
-- belief
-- concept
-- image
-- sound
-- illusion
-- impression
-- agreement
-- inclination
-- tendency
-- sparkle
-- tingle
-- pain
Things like that.

widely known for his theories regarding communicative rationality and the
public sphere. This concept of intersubjectivity is called as:
“Intersubjectivity
of mutual understanding”
Answer:
a = 0.16 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.

where:
Vf = final velocity = 3.2 [m/s]
Vo = initial velocity = 1.1 [m/s]
t = time = 13 [s]
a = acceleration [m/s²]
Now replacing:
![3.2=1.1+a*13\\2.1=13*a\\a=0.16[m/s^{2} ]](https://tex.z-dn.net/?f=3.2%3D1.1%2Ba%2A13%5C%5C2.1%3D13%2Aa%5C%5Ca%3D0.16%5Bm%2Fs%5E%7B2%7D%20%5D)
