Answer:
Electromagnetic radiation
Explanation:
Answer:
t = 1023.9 seconds
Explanation:
Given that,
The average velocity of a Mustang, v = 33m/s
Distance, d = 21 miles = 33789 m
Let the driver takes t seconds. So,
Speed = distance/time
So, it will take 1023.9 seconds to complete the course.
n₂ = index of refraction of glass = 1.58
n₁ = index of refraction of air = 1
θ = Brewster's angle
Brewster's angle is that incident angle at which the the reflected light from the interface of two medium is completely polarized.
Brewster's angle is given as
θ = tan⁻¹(n₂ /n₁ )
θ = tan⁻¹(1.58/1 )
θ = 57.7 deg
hence the Brewster's angle comes out to be 57.7 deg
Answer:
The distance the plane covered while it was accelerating is 80,633.3 m
Explanation:
Given;
initial velocity of the plane, u = 90 m/s
acceleration of the plane, a = 1.5 m/s²
final velocity of the plane, v = 500 m/s
The distance covered by the plane is given as;
v² = u² + 2ad
where;
d is the distance covered by the plane;
500² = 90² + 2(1.5)d
500² - 90² = 3d
241900 = 3d
d = 241900 / 3
d = 80,633.3 m
Therefore, the distance the plane covered while it was accelerating is 80,633.3 m
