SI units or International System of Units is defined as basic set of measurement of seven units. The physical quantities and base units are as follows:
Length is measured in meter (m), mass in kilogram (kg), time in second (s), electric current in ampere (A), temperature in Kelvin (K), luminous intensity in candela (cd) and amount of substance in mole (mol).
Therefore, SI units of physical quantities is known as base units and other units are known as derived units because they can derived from the SI units.
Thus, the correct match will be:
From the rest of the units, degree Fahrenheit is derived unit for temperature, gram is derived unit for mass, nanosecond is derived unit for time and candela is SI unit for luminous intensity.

0.0006 in scientific notation is 6 × 10-4
<h2>Step by step Explanation:</h2>All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.0006 into scientific notation, follow these steps:
Move the decimal 4 times to right in the number so that the resulting number, m = 6, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -4
Write in the scientific notation form m × 10n
= 6 × 10-4
Therefore,
6 × 10-4 is the scientific notation form of 0.0006 number and 6e-4 is the scientific e-notation form for 0.0006
