प्रत्येक मोड़ के बाद कागज़ की मोटाई का क्या होता है?
Answer
हर मोड़ के बाद मोटाई दोगुनी हो जाती है। यह गुणक वृद्धि है, जिसे घातीय वृद्धि भी कहा जाता है। अगर कागज़ 0.001 cm से शुरू होता है, तो 1 मोड़ के बाद यह 0.002 cm हो जाता है, 2 मोड़ के बाद 0.004 cm और 3 मो…
What happens to the thickness of a sheet of paper after each fold?
Answer
The thickness doubles after every fold. This is multiplicative growth, also called exponential growth. If the paper starts at 0.001 cm, then after 1 fold it becomes 0.002 cm, after 2 folds 0.004 cm, a…
Why is paper folding an example of exponential growth?
Answer
Because each fold multiplies the thickness by 2. The growth is not by a fixed amount; it keeps doubling. That is why it is multiplicative growth, not additive growth.
कागज को मोड़ना घातीय वृद्धि का उदाहरण क्यों है?
Answer
क्योंकि प्रत्येक परत मोटाई को 2 से गुणा करती है। वृद्धि एक निश्चित राशि से नहीं होती है; यह दोगुनी होती रहती है। यही कारण है कि यह गुणात्मक वृद्धि है, न कि योगात्मक वृद्धि।…
किसी भी 3 परतों के बाद, मोटाई कितनी गुना बढ़ जाती है?
Answer
किसी भी 3 परतों के बाद, मोटाई 8 गुना बढ़ जाती है। ऐसा इसलिए है क्योंकि 2 × 2 × 2 = 8, इसलिए 2^3 = 8।…
After any 3 folds, by how many times does the thickness increase?
Answer
After any 3 folds, the thickness increases 8 times. This is because 2 × 2 × 2 = 8, so 2^3 = 8.
After any 10 folds, by how many times does the thickness increase?
Answer
After any 10 folds, the thickness increases 1024 times. This is because 2^10 = 1024.
किसी भी 10 परतों के बाद, मोटाई कितनी गुना बढ़ जाती है?
Answer
किसी भी 10 परतों के बाद, मोटाई 1024 गुना बढ़ जाती है। ऐसा इसलिए है क्योंकि 2^10 = 1024 है।…
