Is A vector is a quantity that is fully described by magnitude alone?
No, a vector is a quantity that is fully described by both magnitude and direction. Magnitude represents the size or amount of the vector, while direction indicates the orientation of the vector in space.
Is possession of magnitude and direction sufficient for calling a quantity a vector explain?
No, possession of magnitude and direction alone is not always sufficient for calling a quantity a vector. A vector must also obey the rules of vector addition and scalar multiplication to be considered a true vector in physics and mathematics.
Area is scaler or vector quantity?
Well it is technically a vector because it has a magnitude and a direction on zero degrees. Reactive power will have a direction of either + or - 90 degrees and apparent power will be the vector sum of the real and reactive power.
What quantity has a magnitude but no direction?
scalar
What quantity is completely described by magnitude alone?
Scalar quantity is completely described by magnitude alone, without any direction. Examples include temperature, speed, and mass.

Which are the scalar quantities?
A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity.

Scalar quantity is completely described by magnitude alone, without any direction. Examples include temperature, speed, and mass.
What are properties of a vector quantity?
A vector quantity not only has a size, it also has a direction. Velocity is a vector quantity. "30 mph north" and "30 mph east" are different velocities. "Speed" is a part of velocity ... its size alone, without its direction, so speed is not a vector quantity.
Is velocity scalars or vectors?
It is a vector since it has both a magnitude and a direction. Scalar quantities only have a magnitude.
Why is wind called a vector quantity?
Definitely. In fact, you always see TV weathermen completely describe the wind vector."Winds are from the North at 27."There's the vector . . . magnitude = 27, direction is from north to south.You'll never hear a radio or TV weatherman say "Winds are 20 miles an hour."and leave it at that.At least not the same weatherman for a second time.
are human beings vector quantities or scalar?
A human being is not a measurement. You can measure a human's height, mass, weight, albedo, loudness when he shouts, or whatever, and each of these can be expressed as a measurement, but the human being itself is not a measurement. In general, you have to distinguish an object from its properties.
How do you find the y-component of a vector if you are given the magnitude?
The magnitude alone can't tell you anything about its components. You also need to know its direction.
What are some examples of scalar and vector quantities?
Scalar QuantitiesMost of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy.Vector QuantitiesA vectorquantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis, as shown in Figure 1. Using north/south and east/west reference axes, vector "A" is oriented in the NE quadrant with a direction of 45 north of the o EW axis. G iving direction to scalar "A" makes it a vector. The length of "A" is representative of its magnitude or displacement.Another AnswerA scalar quantity refers only to the magnitude of the quantity and answers the question how much. Ex. height, weight, volume, and the like. 2 lbs of sugar is scalar, 4 m long is scalarA vector quantity refers to both magnitude and direction and answers how much and where is it going, (in that sense)Ex. forces, velocity. 200 km/hr at N30degE is a vector, the force required to push a drum up or down a ramp is a vector, the force exerted by the cue stick in billiards is a vector a scalar is a number, like a distance... like the moon is 300.000km away from earth.a vector is a number AND a direction. It's like "moving east at 100km/h"while "moving at 100km/h" alone is a scalar.The idea is that a scalar has only ONE dimension, while a vector has several.
