## Which quantities have both a magnitude and direction apex?

Velocity has both a magnitude and direction.

## Which quantity has both magnitude and direction choose the correct answer?

vector quantities

## Which has both magnitude and direction speed or velocity?

Velocity has both magnitude and direction that is why it is a vector quantity. Whereas, Speed has only magnitude and no direction that is why it is a scalar quantity.

## Is a quantity which has a magnitude and direction always a vector?

Answer. It is a universal law in physics. If any quantity has direction and magnitude then it ought to be a vector quantity. It is not necessary that a quantity having both direction and magnitude is a vector.

## Has both magnitude and direction is called?

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude.

## Which physical quantity has no direction?

Scaler Quantity

## Which quantity does not show direction?

A scalar is any quantity that has a magnitude, but no direction. For example, a 20ºC temperature, the 250 kilocalories (250 Calories) of energy in a candy bar, a 90 km/h speed limit, a person’s 1.8 m height, and a distance of 2.0 m are all scalars—quantities with no specified direction.

## Do scalar quantities have direction?

A quantity which does not depend on direction is called a scalar quantity. Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude. When comparing two vector quantities of the same type, you have to compare both the magnitude and the direction.

## Does energy have direction?

Energy Around Us That energy must be used to do work, or accelerate, an object. Energy is called a scalar; there is no direction to energy (as opposed to vectors). We also speak of kinetic energy, potential energy, and energy in springs. Energy is not something you can hold or touch.

## Do electric field lines exist?

Electric field lines never intersect. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential. If the electric field in a given region of space is zero, electric field lines do not exist.

## Can you see electric fields?

The science behind seeing electricity Normally, we can’t see electricity. It’s like gravity – an invisible force we only recognise when it acts upon other objects.

## Which quantities have both a magnitude and direction apex?

velocity is the answer. it is a vector quantity. which has both magnitude and direction.

## Which quantity has both magnitude and direction choose the correct answer?

vector quantities

A quantity which has both magnitude and direction is called vector quantities.

## What requires both magnitude and direction?

Explanation: Vector quantities have both magnitude and direction, while scalar quantities have only magnitude. Velocity, acceleration, force, and displacement are all vectors.

## Which quantity has both magnitude and direction but not a vector quantity?

electric current

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.

## Is distance 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 refractive index a vector or scalar?

Ya refractive index has no units and also it is a ratio but also it doesn’t have any direction so it is considered as a scalar quantity.

## Does speed has both magnitude and direction?

Speed is a scalar quantity. It does not change at all with direction changes; therefore, it has magnitude only. If it were a vector quantity, it would change as direction changes (even if its magnitude remained constant).

## What has magnitude but no direction?

A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

## What is both magnitude and direction called?

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position.

## Does mass has both magnitude and direction?

Mass has only magnitude while weight has both magnitude and direction.

## Does speed have both magnitude and direction?

Speed has only magnitude and Velocity has both magnitude and direction.

## Is refractive index a number?

Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n’ in descriptive text and mathematical equations.

## Which scalar quantity has no unit?

Ya refractive index has no units and also it is a ratio but also it doesn’t have any direction so it is considered as a scalar quantity. So there is no magnitude !!!

## Is a value that only has a magnitude with no direction?

In contrast to vectors, ordinary quantities that have a magnitude but not a direction are called scalars. For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.

## What has only magnitude or size?

Scalar and vector quantities 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. Vector quantities have both a size or magnitude and a direction, called the line of action of the quantity.
