Answer:
If the angle of incidence is bigger than the critical angle, the refracted ray will not emerge from the medium, but will be reflected back into the medium. This is called total internal reflection. The critical angle occurs when the angle of incidence where the angle of refraction
It's an aspect of geography that delves into the relationship, including the social, economic and spatial interconnections between people and their environment.

Answer:
1.199km/h towards west
2.17km/h towards upstream direction
3.702km/h towards east
4.2km/h towards downstream direction
5.a.149km/h towards east
b.1043km
Explanation:
1.V p,e = Vp,w + Vw,e
= 211km/h-12km/h
=199km/h towards west
2. Vb,o=Vb,r+Vr,o
Vb,o=22-5km/h
=17km/h towards upstream direction
3.Vj,w= Vj,e + Ve,w
Vj,w = 740-38km/h
= 702km/h towards east
4.Vk,r= Vk,e+ Ve,r
Vk,r=33 - 31km/h
=2km/h towards downstream direction
5.a.Vp,e=Vp,w +Vw,e
Vp,e=216-67km/h
=149km/h towards east
b. distance =speed * time
= 149km/h * 7h
=1043km
