Help, pls. it's due tomorrow night. An airplane flies due north at 200 km/h, and the wind blows in a direction N30°E
at 40 km/h. Find the coordinates for the vector representing the resultant for
the airplane with the wind factored in, and the resultant airspeed. show calculation and a diagram.

a and b sometimes have a positive value

gas and liquid

at right angles to each other

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
