Answer:1.27
Explanation:
Given
incident angle ![i=36^{\circ}](https://tex.z-dn.net/?f=i%3D36%5E%7B%5Ccirc%7D)
refracted angle ![r=27.5^{\circ}](https://tex.z-dn.net/?f=r%3D27.5%5E%7B%5Ccirc%7D)
Suppose
is the refractive index of material then using Snell's law we can write
![n_1\sin i=n_2\sin r](https://tex.z-dn.net/?f=n_1%5Csin%20i%3Dn_2%5Csin%20r)
where
=refractive index of air
![1\times \sin (36)=n_2\times \sin (27.5)](https://tex.z-dn.net/?f=1%5Ctimes%20%5Csin%20%2836%29%3Dn_2%5Ctimes%20%5Csin%20%2827.5%29)
![n_2=\dfrac{0.5877}{0.4617}](https://tex.z-dn.net/?f=n_2%3D%5Cdfrac%7B0.5877%7D%7B0.4617%7D)
![n_2=1.27](https://tex.z-dn.net/?f=n_2%3D1.27)
Examples of medium are solid ,liquid ,and gas basically matter. :D

Explanation:
Answer:I think I’m not sure But I think that the force that would be accurated the car would be friction or something like that and to solve the equation you would do f/m
Explanation:
It just makes sense
