human skin has a thickness of about 5×10⁻³ meter. a grain of sand has a thickness of about 1×10⁻³ meter. which is thicker, human skin or a grain of sand?
Answer
Explanation:
Step1: Compare the thickness values
We have human - skin thickness (5\times10^{-3}) m and sand - grain thickness (1\times10^{-3}) m. Since (5\times10^{-3}>1\times10^{-3}) (when the exponents are the same, we compare the coefficients, and (5 > 1)).
Answer:
Human skin
