A vector has magnitude and direction. You can specify the direction with an angle, then the magnitude depends on what you're measuring (force, velocity, etc.) The direction could also be something specific to the quantity measured, like saying the wind is blowing 15 miles per hour to the Northwest.

The direction of a vector that points somewhere between due north and due east is measured in?
degrees
Is power a vector quantity or a scalar quantity?
vector, power= work/time and work= force * distance, force is vector.
In a 2 - dimensional cartesian coordinate system the y-component of a given vector is equal to the vector magnitude multiplied by which trigonometric function with respect to the angle between vector?
I disagree with the last response. It is implied that the angle you are speaking of is the angle between the x-axis and the vector (this conventionally where the angle of a vector is always measured from). The function you are asking about is the sine function. previous answer: This question is incorrect, first of all you have to tell the angle between vector and what other thing is formed?
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
Is vector A parallel vector B given that vector A is equal to the zero vector and vector B is equal to the zero vector?
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
