## Unravelling the Dynamic Duo: Exploring What is Variables and Constants

## FAQs on Difference Between Variables and Constants

1. Can a variable have multiple values at the same time?

Variables can exist in superposition, or multiple states, as in quantum mechanics, where they can have numerous values at once. However, variables normally take on one value at a time in the majority of actual applications.

2. Can constants be reassigned to new values?

No, constants are defined with fixed values that remain constant throughout a specific context or problem. They cannot be reassigned or modified once their initial value is assigned.

3. Can constants have units of measurement?

Yes, constants can have units of measurement associated with them, depending on the specific physical or mathematical property they represent. Units are used to provide the necessary context for the constant's value.
