The width of a human hair is 2 x 10-5 meters. The width of a piece of sand is 1.5 x 10¹ meters.
Elena L [17]

The difference in the widths, in meters, of the human hair and the piece of sand is 1.4998*10^{-1} m.

It is given in the question that:-

Width of a human hair = 2*10^{-5} m

Width of a piece of sand = 1.5*10^{-1}m

We have to find the difference in the widths, in meters, of the human hair and the piece of sand.

We know that,

Difference between the widths = Width of a piece of sand - Width of a human hair

Hence, we can write,

Difference between the widths =  2*10^{-5} m - 1.5*10^{-1}m

We can write,

1.5*10^{-1}=15000*10^{-5}

Hence,

Difference between the widths =

15000*10^{-5} - 2*10^{-5}= 14998*10^{-5} = 1.4998*10^{-1} m
