## What is vector subscript out of range?

vector subscript out of bounds means accessing memory, that is not under your control. We don’t see your debugger, hence we can’t answer your questions.

**What is a vector subscript?**

A vector subscript is an integer array expression of rank one, designating a sequence of subscripts that correspond to the values of the elements of the expression. A vector subscript can be a real array expression of rank one in XL Fortran.

**How do I get the size of a vector in C++?**

size() – Returns the number of elements in the vector. max_size() – Returns the maximum number of elements that the vector can hold. capacity() – Returns the size of the storage space currently allocated to the vector expressed as number of elements. resize(n) – Resizes the container so that it contains ‘n’ elements.

### What is the default size of vector in C++?

0

**What is the length of a vector?**

The length of a vector is the square root of the sum of the squares of the horizontal and vertical components. If the horizontal or vertical component is zero: If a a or b b is zero, then you don’t need the vector length formula. In this case, the length is just the absolute value of the nonzero component.

**Is magnitude the length of a vector?**

The magnitude of a vector is the length of the vector. The magnitude of the vector a is denoted as ∥a∥.

## What is the length of the vector (- 3 2?

Answer. Answer: √13 is the answer.

**Is length a vector or scalar?**

Length and distance are not vector quantities (they are scalar quantities), but position and displacement are vector quantities (at least according to common terminological conventions).

**Does vector mean distance?**

Distance is an example of a scalar quantity. A vector is any quantity with both magnitude and direction. Some physical quantities, like distance, either have no direction or none is specified. A scalar is any quantity that has a magnitude, but no direction.

### Why mass is scalar?

Note: Mass of a body is scalar quantity. Mass has only magnitude, not direction. If we consider weight it is the force experienced by the object due to its mass. Hence, weight has both the magnitude and direction.

**Is displacement a vector or scalar?**

Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position.

**Why current is called tensor quantity?**

So, since it is the dot product of two vectors, current is a scalar. Most of the confusion is not whether or not current is a vector but rather whether or not you are using current or current density in a particular instant. Note, both scalars and vectors are tensors.

## Does current is a tensor quantity?

So yes, the electric current is a tensor model, but only for the induced part, not the driving part. The distribution of vector fields needs surfaces to exist. It’s differential geometry.

**Is current scalar quantity?**

Complete answer: Electric current is a scalar quantity. When two currents meet at a point the resultant current will be an algebraic sum.

**Is charge a vector quantity?**

Electric charge is a scalar quantity because charge never graduated into the level of vectors or tensors that need both magnitude and direction.

### Is electric flux a vector quantity?

It is a dot product of electric field vector (vector E) and area vector (vector ds). So, electric flux is a scalar quantity.

**Is heat a vector quantity?**

Heat is always transferred in the direction of decreasing temperature. Temperature is a scalar, but heat flux is a vector quantity.

**Is electricity a vector quantity?**

Power is energy (or work) per unit time. Time is not considered a vector quantity, and neither is energy or work — work isn’t directional. So power is the ratio of two scalar quantities, and is thus scalar, not vector.

## Is EMF scalar or vector?

Electromotive force (EMF) is a scalar quantity.

**Is angular momentum is a vector quantity?**

Angular momentum is a vector quantity, requiring the specification of both a magnitude and a direction for its complete description.

**Which type of quantity is the power?**

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.

### Is force a scalar quantity?

Force cannot be described using a scalar, since force has both direction and magnitude; however, the magnitude of a force alone can be described with a scalar, for instance the gravitational force acting on a particle is not a scalar, but its magnitude is.

**Can power be negative?**

Generally, if something absorbs power, the power is positive. Anything that provides power is negative. This actually comes from the formula P = I*V (I is current, V is voltage, and P is power) and the sign conventions for current and voltage.

**Is density a vector quantity?**

since density is a scalar quantity. Thus density can be expressed as vector using scalar density field.

## Which is the following is not a vector quantity?

Distance is the quantity which is not vector.

**Which of following is a vector quantity?**

Vector Quantity: A physical quantity is said to be a vector quantity when it has both magnitude and direction. The scalar quantities are distance, mass, time, volume, density, speed, temperature, and energy, The vector quantities are weight, velocity, acceleration, and force.

**What is the quantity of density?**

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of air is 1.2 kilograms per cubic metre.
