Phys 10 the speed of light is roughly 300,000,000 meters per second (m/s). in scientific notation, this quantity is:

The speed of light = 300,000,000 m/s

As this number is too large.So we often use scientific notation to represent large values as well as small values

Now to represent  300,000,000 m/s  to scientific notion

                  =3×(100000000) m/s

                  =3×10⁸ m/s

 Where 8 is exponent
