Sorry i don’t understand would love to help tho !
Answer:
the index of refraction of the coating is 1.33
Explanation:
Given the data in the question;
refraction index of interior portion of the rod η
= 1.55
angle of incidence θ
= 59.5°
From Snell's law, we know that;
η
× sinθ
= η
× sinθ
where η
is the index of refraction of the rod ( material 1 )
θ
is the angle of incidence
η
is the index of refraction in outer coating ( material 2 )
θ
is the angle of refraction
so we substitute our values into the equation;
η
× sinθ
= η
× sinθ
1.55 × sin( 59.5° ) = η
× sin( 90° )
1.55 × 0.861629 = η
× 1
1.3355 = η
× 1
η
= 1.33 { 2 decimal places }
Therefore, the index of refraction of the coating is 1.33
Answer:
48 meters north
Explanation:
If you measure the distance between the point Marus started and the point where they stopped after traveling 1,250 meters back south, you get 48 meters. To make this a displacement quantity, you add 'north' to the end and get 48 meters north, considering this was the initial direction of the motorcycle.
