Standard form

It is impossible to do Physics without mathematics, therefore you need to polish your rusty mathematics skill .

Some physical quantities have extremely large magnitudes.
These extremely large and small values can be written in standard form ( scientific Notation ) so that it is neat, simple and easy to read.

Example :
a) Diameter of the earth is
= 130 000 000 metres
= 1.3 x 10⁷

b) Length of Paramyxoviruses
= 0.000014 m
= 1.4 x 10^-5


Polish my skills :

Write the following quantities in standard form :

a. The length of virus = 0.00 000 008 m
b. Red light wavelength = 0.00 000 067 m
c. the mass of a ship = 75 000 000 kg
