True

The length of the arrow represents the magnitude.

That depends on what the vector, itself, represents. For example, if the vector represents velocity, then the magnitude of the vector represents speed. If the vector represents displacement, then the magnitude of the vector represents distance.

To specify a vector, you need a length (or magnitude), and a direction.

the answer is 12.

A vector represents distance and direction by having both a magnitude (length) that denotes the distance and a direction in space. The magnitude of the vector indicates how far the point is from the origin, while the direction shows the orientation in which the point is located in relation to the coordinate system.

A vector quantity has both magnitude and direction. It is represented by an arrow where the length represents the magnitude and the direction represents the direction. Examples of vector quantities include displacement, velocity, acceleration, and force.

True

The direction of the arrow represents the direction of the force; the length of the arrow is proportional to the magnitude of the force.

direction in space. It is represented by an arrow, where the length of the arrow represents the magnitude and the direction it is pointing represents the direction of the vector. Vectors are commonly used in physics to represent forces, velocities, and other physical quantities.

A vector has magnitude, which represents its length or size, and direction, which indicates where the vector points in space.

The magnitude of a vector is indicated by the length of its arrow.

A vector has two properties: magnitude and direction. The representation of a vector is an arrow. The tip of the arrow points to the direction the vector is acting. The length of the arrow represents the magnitude.

An arrow is commonly used to represent vector quantities in physics. The direction of the arrow indicates the direction of the vector, while the length of the arrow represents the magnitude of the vector.

Start with a point O. Draw a line OA in the direction of the first vector and whose length represents the magnitude of that vector (to some scale). From A, draw the line AB in the direction of the second vector and whose length represents the magnitude of that second vector (to the same scale). Then the direction and length of the straight line OB represent the direction and (to the same scale) the magnitude of the resultant vector.

Magnitude of the force.

Vector quantities have both magnitude and direction. Examples include force, velocity, and acceleration. These quantities are represented by arrows where the length of the arrow represents the magnitude and the direction of the arrow represents the direction.
