26 miles is roughly 41.84 kilometers. So all we have to do is put 41.84 over the time.
 
41.84/4.5

<u>9.298 km/hr</u>

Which of the following phrases defines the angle of refraction?
Sophie [7]
<h2>Answer:The angle between the refracted ray and the normal.</h2>

Explanation:

Refraction is defined as the phenomenon of bending or changing course of a light ray when it passes from one medium to another medium.

The new ray formed after the bending at the surface of new medium is called the refracted ray.

The angle between the refracted ray and the normal of the point on the surface of the new medium where the ray enters is called angle of refraction.

Refer the attachment for instance.

In short,it is the angle between the refracted ray and the normal.

Lindsay is planning a flight from St. Catherines to Hamilton, which lies due west of St. Catharines.
Schach [20]

Lindsay should fly the plane in the direction [W 12.5° S] to get Hamilton.

Using Sine rule to solve this question

Sine rule => SinA/a = SinB/b = SinC/c = constant

The magnitude of wind is 50 with an angle of 60 degrees.

The magnitude of plane is 200 and the angle at which it should fly is unknown and should be θ.

One side is 50 km/hr at an angle of 60 degrees.

sin 60°/200 = sin θ / 50

50 × sin 60° = 200 × sin θ

√3/2 = 4 × sin θ

√3/8 = sin θ

sin θ = 0.2165

θ = sin⁻¹(0.2165)

θ = 12.5°

So Lindsay have to fly the plane in the direction of [W 12.5° S].
