Answer:
4:5
Step-by-step explanation:
Binh's = 40
Davina's = 50
40:50 = 4:5
The answer to this question is 3744
The length of the circumference is (being
the diameter, and using 3.14 for
):
The perimeter of the hexagon is 12 cm.
Hence, the circumference is 0.56 cm longer than the perimeter of the hexagon.
Answer: trapezoid
Step-by-step explanation: A <u>trapezoid</u> is a quadrilateral
with exactly one pair of parallel sides.
Also, quadrilaterals are two-dimensional shapes.
So it's impossible that's its 3-d.
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°
