Because they move with wind currents (which can be different at different altitudes). If they are going in opposite directions, they cannot be at the same altitude. If they were at the same altitude, they would be subject to the same winds, so could not be going in opposite directions.
It's because of the wind.

a node results from the superposition of two waves going in the opposite directions. Where the node is, the two waves cancel each other out.
Forces are vector quantities. This means they have both a magnitude and direction associated with them. If you add vectors going in the opposite directions it is the same as subtracting one from the other. Therefore, the resultant force is the difference between the forces.
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
Velocity can be a positive or a negative because velocity is a vector, which means it is also affected by direction. This that if one car is going +10 m/s and another is travelling at -10 m/s, this means that they are travelling the same speed in opposite directions.
Assuming the two forces are acting ON THE SAME OBJECT, you can subtract the two forces, to get the net force. Important: This does not apply to Newton's Third Law, since the forces act on DIFFERENT OBJECTS. I mention this because people tend to get this confused.
Hot air balloons are steered by changing altitude. The air currents are often going different directions at different altitudes, and by changing altitude you can get into an air current going the direction that you want to go. This isn't complete control like the steering on a car or airplane, you are still limited to the directions that the wind is going, but you have some control.
According to google maps, it is approximately 1,621 miles (~2,609 km) from Albuquerque, NM, to Winnipeg, MB, Canada. If you'd like directions, try going to www.google.com and typing 'Albuquerque to Winnipeg', then searching....then after you search, click 'Maps' at the VERY top of the results page.

Uh...they were going in opposite directions?
yes
Start in the same point but are going in opposite directions
Is a solid yellow line to my left on the road means what
Because we can't see the image you're referring to, we can't give the answer to which ray is opposite to BA. However, we can help. Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. So, if there are two rays (BA and BC) with a common endpoint (B) going in different directions, they are called opposite rays.
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
Never, since they are travelling in opposite directions.. . . but probably not the one the algebra book's authors intended....If you assume that "opposite directions" means the cars are travelling towards each other, their closing speed (i.e. relative speed) is 105 mph. That means they'll meet in 100/105 hours, or slightly more than 57 minutes.
On a road, a solid line divides lanes of traffic which are going in opposite directions. A line composed of dashes divides lanes of traffic going in the same direction.
i dont really understand what your saying, Take a rubber band for example if your stretching it is it going in 2 directions or 1? Confusing isn't it?
