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 is meant by unit of a physical quantity?
A unit of a physical quantity is a standardized quantity used to express measurements. These units help provide a clear and consistent way to quantify different physical properties such as length, mass, time, and temperature. Units allow for effective communication and comparison of measurements across different contexts.
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.
What is considered vector quantity?
A vector quantity is a physical quantity that has magnitude and direction, such as velocity, force, and acceleration. This means that in addition to knowing the size of the quantity, you also need to know the direction in which it is acting.
Can a quantity be dimensionless and have no units?
Yes, a dimensionless quantity is a quantity that does not have any physical dimensions or units. It is a pure number or ratio that represents a comparison between two quantities. Examples of dimensionless quantities include angles, ratios, and pure numbers like pi.
What is fluid gradient?

What does the inverse square law state?
any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.
Quantity?
Any physical property that can be measured and represented in numbers.
What is significance of correlation?
it shows any pattern that may emerge in any given set of date, this includes a positive or negative correlation. positive where a gradient goes from low to high negative where a gradient goes from high to low
In imperial system we what measure?
Any physical quantity, but in mostly obsolete units.
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.
Why expectation values are used?
In quantum mechanics,we are not certain about any physical quantity(unlike classical echanics).So,here value of every physical quantity can only be approximated or expected
What is difference between a physical quantity and a number?
A physical quantity is a number of object(s) that are tangible objects. A number doesn't have to represent any specific quantity of items, but rather just a quantity in an equation. Phsyical quantity: 5 chairs, 2 apples
