Which scalar quantity has both direction and magnitude?
Understanding Scalar And Vector Quantities : Example Question #2. Which of the following is a vector quantity? Explanation: A vector has both magnitude and direction, while a scalar has only magnitude.
Which of the following has both direction and magnitude?
A vector is a quantity that has both magnitude and direction.
Which quantity has both magnitude and direction but not a vector?
Another such quantity that has both magnitude and direction but is not a vector is electric current. Electric current has a certain magnitude and direction of flow. However, two currents are always added algebraically similar to scalars.
Does pressure have both magnitude and direction?
Hence pressure is a scalar quantity. So pressure has magnitude but no specific direction.
What measurement has both size and direction?
A vector is a measurement that has both size and direction and may be represented by an arrow. A vector can be used to represent both distance and direction of motion.
Is vector a physical quantity?
A vector quantity is defined as the physical quantity that has both directions as well as magnitude. A vector with the value of magnitude equal to one is called a unit vector and is represented by a lowercase alphabet with a “hat” circumflex i.e. “รป”.
Why vector has both magnitude and direction?
Does it mean that anything that has magnitude and direction is necessarily a vector ? The rotation of a body can be specified by the direction of the axis of rotation, and the angle of rotation about the axis.
Which of the following gives both direction and magnitude vector or unit vector?
Answer. b) vector is the correct option.
What is the magnitude and direction of vector?
A vector is a directed line segment with an initial point and a terminal point. Vectors are identified by magnitude, or the length of the line, and direction, represented by the arrowhead pointing toward the terminal point. The position vector has an initial point at (0,0) and is identified by its terminal point โจa,bโฉ.
Which of the following gives both direction and magnitude Mcq?
Force is a vector quantity which has both magnitude and direction. 9.
What explains a quantity that has both speed and direction?
Vector, in physics, a quantity that has both magnitude and direction.
What is called if a body possess only magnitude and direction of velocity?
Vector quantity A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass, energy and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force, weight, acceleration and velocity.
Does momentum have direction and magnitude?
momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.
What is a vector and scalar?
Vectors have magnitude and direction, scalars only have magnitude. The fact that magnitude occurs for both scalars and vectors can lead to some confusion. There are some quantities, like speed, which have very special definitions for scientists. By definition, speed is the scalar magnitude of a velocity vector.
What is a vector quantity?
Vector Quantity Definition The physical quantities for which both magnitude and direction are defined distinctly are known as vector quantities.
What has magnitude but no direction?
Scalar Quantities are those which have magnitude but no direction. Eg: Distance, Speed, Work, Temperature etc.
Is density a vector quantity?
Current density is a vector quantity.
Which is a scalar quantity?
Scalar quantities have a size or magnitude only and need no other information to specify them. Thus, 10 cm, 50 sec, 7 litres and 3 kg are all examples of scalar quantities. (b) Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity.
Is velocity a vector?
Speed is a scalar quantity โ it is the rate of change in the distance travelled by an object, while velocity is a vector quantity โ it is the speed of an object in a particular direction.
Is force a vector?
A force has both magnitude and direction, therefore: Force is a vector quantity; its units are newtons, N. Forces can cause motion; alternatively forces can act to keep (an) object(s) at rest.
Are all physical quantities that have magnitude and direction vectors give example to support your answer when is a physical quantity called vector?
Yes, definitely there exists physical quantities which have magnitude as well as direction but are not vector quantities. One such example is “Current”. It has made and direction both but still it’s not a vector quantity.
What is the magnitude and direction of the force?
Magnitude of a Single Force Vector Extending the link, the angle the hypotenuse makes with the base is the direction of the force. So, 5 N is the magnitude of force.
How do you find the magnitude and direction of an electric force?
We can use the equation E = k | Q | r 2 E = k | Q | r 2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge, which is negative in this case. E = k | Q | r 2 = ( 8.99 ร 10 9 N โ m 2 /C 2 ) | โ 1.5 ร 10 โ 9 C | ( 0.035 m ) 2 = 1.1 ร 10 4 N/C.
