This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Area can be represented as a vector quantity because it has both magnitude and direction. The direction of area vector
of a surface is along the perpendicular to the surface.
Is area is a scalar quantity?
The magnitude of area is a scalar quantity.
How is area vector defined?
: the vector of a plane surface whose magnitude is the area of the figure and whose direction is that of a perpendicular to the plane of the figure.
How do you know if its scalar or vector?
A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it. Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude.
Is a plane a vector area?
Hint: Area vector is a vector quantity related to the plane or curved surface. If the area of the surface is A and the normal unit vector to the plane or surface is ˆn then the area vector is given as Aˆn. Now, get the correct option related to the area vector with the help of above definition.

Is density scalar or vector?
Most recent answer
since density is a scalar quantity. it does not inherently shows the direction. thus different in density between two points in flow filed is expresses as scalar density field or density gradient at point at given instant of time. Thus density can be expressed as vector using scalar density field.
Is electric flux a vector quantity?
Is Electric flux a scalar or a vector quantity? Answer: Electric flux is a scalar quantity. It is a scalar because it is the dot product of two vector quantities, electric field and the perpendicular differential area.
Can time be a vector?
From a modern physics viewpoint, time is not a vector nor a scalar, it is a coordinate. This is because time is relative depending on the observer, so it cannot be defined as a scalar or a vector. In Newtonian physics, however, time has a universal meaning and is usually thought of as a scalar.
Is acceleration a vector or scalar?
For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination.
Is pressure a vector or scalar?
Therefore, pressure is a scalar quantity, not a vector quantity. It has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface.
What is difference between area and area vector?
It is equal to the surface integral of the surface normal, and distinct from the usual (scalar) surface area. … Vector area can be seen as the three dimensional generalization of signed area in two dimensions.
What is a total surface area?
The total surface area of a solid is the sum of the areas of all of the faces or surfaces that enclose the solid. The faces include the tops and bottoms (bases) and the remaining surfaces. … The sum of the areas of the rectangle and the two circles is the total surface area.
What is vector data structure?
Vector is a data structure, used to store spatial data. Vector data is comprised of lines or arcs, defined by beginning and end points, which meet at nodes. The locations of these nodes and the topological structure are usually stored explicitly.
Is current scalar quantity?
Electric current is a scalar quantity. Any physical quantity is defined as a vector quantity when the quantity has both magnitude and direction but there are some other factors which show that electric current is a scalar quantity . When two currents meet at a point the resultant current will be an algebraic sum.
What is scalar and example?
Scalar, a physical quantity that is completely described by its magnitude; examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors.
Why is area scalar?
Still only area is a scalar. Area can be represented as a vector quantity because it has both magnitude and direction. The direction of area vector of a surface is along the perpendicular to the surface. … Then, area is scalar.
Is vector quantity a force?
(Introduction to Mechanics) vector quantities are quantities that possess both magnitude and direction. A force has both magnitude and direction, therefore: Force is a vector quantity; its units are newtons, N.
Which is not a vector quality?
Speed is not a vector quantity. It has only magnitude and no direction and hence it is a scalar quantity.
What are 3 types of acceleration?
The three types of acceleration are 1) Change in velocity 2) Change in direction 3) Both change in velocity and direction .
Is distance is a vector quantity?
Displacement is an example of a vector quantity. Distance is an example of a scalar quantity. A vector is any quantity with both magnitude and direction.
Is temperature a vector or a scalar?
Temperature is an example of a scalar physical quantity; it has a magnitude associated with it, but no directional sense. Other examples of scalar quantities include pressure, energy, concentration or density.
What is SI unit of electric flux?
Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C−1). Thus, the SI base units of electric flux are kg·m3·s−3·A−1.
Is dipole moment a scalar or vector?
Electric dipole moment is a vector quantity and it is represented as →p=q×→d in vector form.
Why is flux a vector?
For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface.
Is electrical resistance scalar or vector?
Voltage is a scalar quantity and can be calculated by the product of current (scalar) and resistance (scalar). Work is a vector quantity and can be calculated by the product of a force (vector) and displacement (vector).
