How are velocities in the same direction combined?
As the velocities are in the same direction then addition of vectors becomes so easy. We simply add the magnitudes of the velocities. If velocities go exactly opposite, then we get the difference of their magnitudes. If velocity vectors get inclined, then we use the parallelogram law of vectors to get the resultant.
Physical values in the real world have two componets magnitude and?
Some physical values - not all of them - have a magnitude and a direction. Such physical values are known as vectors. As an example, when applying a force, a direction is often relevant. Also, when specifying a speed, a direction may be relevant (you end up in quite different places if you go north vs. east, for example). In physics, a speed, combined with a direction, is called a velocity.
Where can you get a premade sun vector?
Go to photobucket.com & type in sun vectors. (:
How do you find the direction of a cross product vector?
Think of a screw-thread, threaded just like a screw that you might use to screw a hook into a piece of wood. In the US, all woodscrews are manufactured with what's called a "right-hand thread". That means you turn it right to go into the wood, and you turn it left to bring it out of the wood. Now keep that 'right-hand thread' in the back of your mind, and we'll look at a vector cross-product. A cross-product is the new vector you get when you operate on two vectors that you already have. You obviously know the directions of the vectors that you already have, and you're asking "What is the direction of the new vector ?". Well, call the first two vectors 'A' and 'B'. If you do the cross-product (A x B), think of that right-handed screwthread rotating from the 'A' direction to the 'B' direction. What direction did the right-hand thread advance ? That's the direction of the cross-product ! Can you picture the three-dimensional Cartesian coordinate system ? Down at the origin, where the three axes come together, if you draw three little tiny vectors down on the three axes, you'll notice that ( x cross y = z ). This will help you a lot if you ever have to draw the axes properly on a blank sheet of paper. Notice that (B x A) goes in the opposite direction of (A x B), because when you turn a right-hand thread the other way, the screw advances oppositely. Another contributor may improve this answer by describing the "Right Hand Rule", which is another, maybe better, way to get the direction of the cross product. If he is not a total genius at descriptive language, it will confuse you.
In what way does friction always act?
And it not only DOES; it works in no other way. Friction is a sneaky thing. You know how a thermos "knows" to keep the hot stuff hot and the cold stuff cold? Well, friction always knows in which direction you're trying to go and pushes against you!

Combined Vectors that go only forward or backward are one demensional?
True
How are vectors useful to moving objects?
they have both direction and magnitude. They can go in one direction and thus have a magnitude in that direction... uh yeah

Problems regarding graphical method of determining resultant vector?
When you add vectors graphically you connect them head to tail, keeping their length and direction constant. The difference from the tail of the first one to the head of the last one is the resultant vector. Go to the related link below.
