Question

Q The thickness of human hair is approximately 5 X 10 to the power-3

cm. How many

strands of human hair together will be 1 cm thick?
​

Answer 1

Answer:

2 x $10^{2}$ hairs

Step-by-step explanation:

5x$10^{-3}$ cm = 1 human hair

1 cm = ? human hair

Clearly, ?= $\frac{1 x 1}{5 x 10^{-3} }$ hairs

              = $\frac{1}{5}$ x $10^{3}$ hairs

              = 0.2 x $10^{3}$

              = 2 x $10^{2}$

Hence,  2 x $10^{2}$ human hairs will be needed to be stuck together to make it 1 cm thick
