What is the significance of the divergence of a scalar times a vector in the context of vector calculus?
The significance of the divergence of a scalar times a vector in vector calculus is that it simplifies to the scalar multiplied by the divergence of the vector. This property is important in understanding how scalar fields interact with vector fields and helps in analyzing the flow and behavior of physical quantities in various fields of science and engineering.
What cannot be a scalar quantity?
A scalar quantity is something that only has magnitude and no direction. Any physical quantity that has both magnitude and direction, such as velocity or force, cannot be a scalar quantity.
What does a scalar measure?
A scalar is a quantity that has only magnitude and no direction. In terms of measurement, a scalar measure is a numerical value representing the size or magnitude of a physical quantity without specifying the direction. Examples of scalar measures include temperature, distance, and speed.
What is the formula of scalar quantity?
Scalar quantity is a physical quantity that has magnitude only, without any direction. It is often represented by a number with a unit. There is no specific formula for scalar quantity as it is independent of directions. Examples of scalar quantities include mass, temperature, and speed.
Is 30 apples a scalar quantity?
No, 30 apples is not a scalar quantity. Scalar quantities are physical quantities that have magnitude only, with no direction. In this case, the quantity of apples has magnitude (30) but also has a directional component (apples).

What is scalar field?
In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.
What physical quantity has a direction but no magnitude?
scalar

Scalar physical quantity used to describe change?
watt
When a vector is multiplied by a scalar physical quantitythen what will be dimensions of resulting vector?
The same as the original vector. The scalar will change the numbers, but not the dimensions.
Why is force a scalar quantity?
Force is not a SCALAR because it always has a DIRECTION, making it a VECTOR. A SCALAR quantity is a one-dimensional physical quantity, i.e. one that can be described by a single real number.

Which physical quantity is obtained when acceleration is differentiated with respect to time is it a scalar or vector or tensor?
For differentiation, you have to divide a vector by a scalar. Therefore, you should get a vector.
What is light life science or physical science?
physical science
Is cosmology life science or physical science?
It is physical science.
