The centripetal acceleration of an object is given by the relation,
where Ac = centripetal acceleration =
R = radius of rotation = 15 m
V = speed of astronaut
Hence,
solving this we get, V = 38.34 m/s
Answer:
The refractive index of the plastic, n₂ is between 0.73696 and 0.85034
Explanation:
Here we have;
Snell's law which is the relationship of the refractive index of light in two media. The law, in mathematical terms, states the ratio of the refractive index of light between two media is inversely proportional to the ratio of the sine of the angle of incidence to the sine of the angle of refraction.
That is the sine of the angle of incidence and the sine of the angle of refraction are inversely proportional.
0.79365 ± 0.05669
If θ₂ = Angle inside the plastic object and
θ₁ = Angle outside the plastic object
n₁ = Refractive index of air outside the plastic = 1
n₂ = Refractive index of the plastic
Therefore, , which gives;
∴ 0.73696 ≤ n₂ ≤ 0.85034.
The refractive index of the plastic, n₂ is between 0.73696 and 0.85034.
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individualwaves upon the particles of the medium.Hope this help!
