200 miles and 480 miles so the answer would be the second car travelled 280 miles further
Answer:
12.99km
Step-by-step explanation:
Using the formula
C=2(pi)(r)
Answer:
A
Step-by-step explanation:
4/5x3= 12/5
Answer:
x = 17.2
Step-by-step explanation:
cos 35 = x/21
0.8192(21) = x
x = 17.2
Answer:
θ = 36.94°
Step-by-step explanation:
Brewster's law for polarization states that; tan(θ_p) = n2/n1
Where ;
θ_p is the polarizing angle
n1 is the index of refraction of first material
n2 is the index of refraction of second material
Now, our first material here is air while second material is water.
Index of refraction of water = 1.33 while index of refraction of air is 1
Thus,
tan(θ_p) = n2/n1 = 1.33/1
tan(θ_p) = 1.33
(θ_p) = tan^(-1)1.33
(θ_p) = 53.06°
Now, polarizing angle is the angle of incidence for which all the reflected light is polarized and it's above the vertical. Thus to get the angle to the horizontal, it will be;
θ = 90° - (θ_p) = 90° - 53.06° = 36.94°
