6 फीट लंबे व्यक्ति की ऊंचाई नैनोमीटर में कैसे व्यक्त की जाएगी (लगभग)?
How will the height of a 6 feet tall person be expressed in nanometers (approximately)?
SELECT CORRECT OPTION:
A
$183 \times 10^6$ नैनोमीटर
$183 \times 10^6$ nanometers
B
$234 \times 10^6$ नैनोमीटर
$234 \times 10^6$ nanometers
C
$183 \times 10^7$ नैनोमीटर
$183 \times 10^7$ nanometers
Correct
D
$181 \times 10^7$ नैनोमीटर
$181 \times 10^7$ nanometers
Official Solution & Explanation:
Correct Answer: Option C($183 \times 10^7$ नैनोमीटर)
$1 \text{ नैनोमीटर} = 10^{-9} \text{ मीटर}$। $1 \text{ फीट} = 0.3048 \text{ मीटर} \approx 30.5 \times 10^7 \text{ नैनोमीटर}$। अतः $6 \text{ फीट} = 6 \times 30.5 \times 10^7 \approx 183 \times 10^7 \text{ नैनोमीटर}$।
$1 \text{ nanometer} = 10^{-9} \text{ m}$. $1 \text{ foot} = 0.3048 \text{ m} \approx 30.5 \times 10^7 \text{ nm}$. Therefore, $6 \text{ feet} = 6 \times 30.5 \times 10^7 \approx 183 \times 10^7 \text{ nanometers}$.
