... the angular tilt of the Earth's position on its axis relative to the sun
Answer:
b) the refracted ray has an angle of 90 degrees
Explanation:
The angle of incidence is measured with respect to the normal separation of the media. The critical angle for total internal reflection occurs is:

Here
and
are the refractive index of the mediums. This equation is an application of Snell's law, for the case where the refracted ray has an angle of
.
Answer:
Save the file and try to put stuff over the file. (kinda off like a picture)
Answer:
The answer is the kinetic energy of sled B after it crash is 6439j.
Answer:
The other angle is 120°.
Explanation:
Given that,
Angle = 60
Speed = 5.0
We need to calculate the range
Using formula of range
...(I)
The range for the other angle is
....(II)
Here, distance and speed are same
On comparing both range






Hence, The other angle is 120°
