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.


What is the name given to the physical quantity which can be completely described by specifying both magnitude and direction. name four such quantities?

That's a 'vector'. Examples include displacement, velocity, acceleration, force,momentum, torque, gradient, divergence, and curl.Distance, speed, temperature, price, weight, energy, power, voltage, resistance,and duration are not vectors.


A vector is a quantity with magnitude and ___?

A vector is described by magnitude and direction (a scalar has only magnitude).


What quantity has a magnitude but no direction?

scalar


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.


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..........


Is quantity described by both magnitude and direction is a vector?

Yes


A physical quantity described by both magnitude and direction is called what?

A physical quantity described by both magnitude and direction is called a vector. Vectors are commonly represented by an arrow pointing in a specific direction, with the length of the arrow representing the magnitude of the quantity.


A 20 newton force moves an object southeast What two properties of force have been described?

The two properties described are magnitude (20 newtons) and direction (southeast).


Is speed a scalar quantity or vector quantity?

Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.


How many types of quantities?

there are three types of quantities:-1.Scalar quantities - Scalarsare quantities that are fully described by a magnitude (or numerical value) alone.2.vector quantities - Vectorsare quantities that are fully described by both a magnitude and a direction.3.Tensor quantities - tensors are quantities that are fully described by magnitude, direction and the plane thecomponent acts on.


What is magnitude of speed?

Magnitude of speed refers to the numerical value of an object's speed without any indication of direction. It is a scalar quantity that describes how fast an object is moving without specifying the direction of motion.
