Work Step by Step
a) SI base units: The SI (International System of Units) base units are a set of seven standard units used to measure physical quantities. These units provide a standard and internationally recognized system for measurement in scientific and engineering fields.
(b) Significant figures: they are the number of digits that are considered reliable or significant in a measurement or calculation.
(c) Natural law: A claim that describes an observed pattern in the natural world and has been supported by numerous observations and experiments is known as a natural law. These rules, which are used to describe and forecast the behavior of physical systems, are typically stated in mathematical equations.
(d) Exponential notation: Whether expressing large or tiny numbers, exponential notation, commonly referred to as scientific notation, uses powers of 10. A number is expressed in exponential notation as a coefficient multiplied by 10 raised to a power.
