Is plane angle a vector or scalar?
It is a scalar.
Can a scalar quantity be made into a vector quantity by adding a direction to its magnitude why or why not?
Yes this happens in case of area. Usually area is a scalar quantity. But we provide the direction of course perpendicular to its plane area we make it as a vector. Same way though electric current is not a vector it is sensed as vector as we put along with length of conductor. I is scalar but Idl is vector.
Why vector quantities cannot be added and subtracted like scalar quantities?
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
Is calories a scalar or a vector quantity?
well, by definition vector is something that has both direction and magnitude, in this case weight is only countable when gravity exists, and of course gravity has direction direction for vector doesnt have to be like north, south or within the plane because vectors are free and can be moved anywhere without changing its magnitude.
What is complainer vector?
Coplanar vectors are vectors lying in the same plane.

How do you determine if -y x is a two dimensional vector or not?
(-y, x) is generally a point in the Cartesian plane - not a vector nor a scalar. You can have a vector going from any point in the plane to the point (-y, x) but that is not the same thing.

Is angle scalar or vector?
Almost all of us would say that angle is a scalar quantity. But the beauty is that angle is a vector quantity. Now the question arises. Where will be the direction? As we measure the angle in a plane in counter clockwise direction, then direction of angle vector will be perpendicular to the plane and coming out of the surface. If the angle is measured in clockwise then vector would go into the surface normally. As angle becomes vector then angular velocity w = @/t also becomes a vector.

Is area a vector or a scalar quantity?
it's a rather puzzling idea, but area can be either a scalar or vector quantity. Usually area is a scalar quantity. E.g. the area of my house is 2000 square feet. In more advanced calculus courses you'll run into area vectors. area is a vector because as u know pressure=force/area which is scalar"pressure"=vector"force" / X"area" area"X"= force/pressure which is vector/scalar =vector so area is a vectorIn geometry, for a finite planar surface of scalar area S, the vector area : is defined as a vector whose magnitude is S and whose direction is perpendicular to the plane, as determined by the right hand rule on the rim (moving one's right hand counterclockwise around the rim, when the palm of the hand is "touching" the surface, and the straight thumb indicate the direction). :
Why pressure is a scalar quantity while stress is a vector?
For specifying pressure u need only magnitude, but for specifying stress u need magnitude,direction and plane Remember stress is not a vector but it is 2nd order tensor..........
When on a plane do passengers fly or ride?
Passengers fly on a plane.
Is reactive power a vector or scalar?
I am not sure what exactly you mean by "reactive power" (I guess you mean electrical reactive power), but power is the ratio of energy for a period of time. So that makes power (and reactive power as well) a scalar, since you can describe it with only one number. The fact that electrical reactive power is drawn on a XY plane, should not confuse you.

Is electric potential difference a vector?
We generally think of electric current as a scalar quantity. When we think of 1/4th amp or 20 amps, we think of an amount (a scalar quantity) of current flow. On another plane, the electromagnetic forces at work in current generation are actually force vectors. In the traditional sense, electric current, which is the movement of electrons, is from negative to positive. This is not a vector, though. In the macro or "large" world, think of current as scalar.---------------------------------------------------------------------The beauty is that though current is not a vector definitely its direction of flow is used to make length as vector. I is not vector. dl is not vector but I dl will be considered as vector. So innovative and essential concept.Current density is a vector which appears in Maxwell's equations.
