Expert Solution

(a) SI (le Système International d'Unités) base units are seven decimal-based measurement systems used to quantify length, mass, time, electric current, temperature, luminous intensity and amount of a substance.

(b) Significant figures are an indication of the capability of the measuring device and how precise can the measurement can possibly be.

(c) Natural law is the reduction of observed data into a simple mathematical or verbal expression.

(d) Exponential notation is a method of expressing numbers as multiples of powers of 10.
