Answer:
45.93°
Explanation:
The angle of incidence is given as 32.7°
The refractive index of the water that is
Refractive index of the air that is (because the refractive index of air is 1 )
We have to find the angle at which the light leave the water means angle of refraction
So according to snell's law
r =45.93°
So the light leave the water at an angle of 45.93°
Answer: East of North
Explanation:
We have the following data:
Speed of the wind from East to West:
Speed of the bee relative to the air:
If we graph these speeds (which in fact are velocities because are vectors) in a vector diagram, we will have a right triangle in which the airspeed of the bee (its speed relative to te air) is the hypotense and the two sides of the triangle will be the <u>Speed of the wind from East to West</u> (in the horintal part) and the <u>speed due North relative to the ground</u> (in the vertical part).
Now, we need to find the direction the bee should fly directly to the flower (due North):
