Share & grow the world's knowledge!
We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
A potential difference of 200 V is maintained across a conductor of resistance 100 Ω The number of electrons passing through it in 1 second is
The correct answer is (b) 2.5 × 10¹⁸. Using Ohm’s law, I = V/R =200V/100Ω =2A. The charge flow per second is Q = It = 2C. The number of electrons is Q/e = 2/(1.6 × 10⁻¹⁹) = 2.5 ×10¹⁸. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-1/

The manuscript intrigued me because it demonstrated how people preserved knowledge before books and printing. The careful craftsmanship, the use of natural inks and the structured script fascinated me. It was amazing to see a document that had survived for centuries, reflecting the patience and dedication of early scholars. The artefact also emphasized the importance of preserving written history, as it contained knowledge that might have otherwise been lost. Seeing it in a museum reinforced the value of conserving our historical documents.

The history of artefacts can be presented through various formats like digital slideshows, posters, short documentaries and live storytelling sessions. Using charts and detailed labels provides structured information about each object. A video demonstration explaining its use and significance makes it more engaging. Virtual museum tours or 3D models allow interactive learning. Role-play or dramatized narratives can help in bringing history to life. Displaying QR codes linked to additional research materials also enhances visitor engagement and understanding.

An ancient palm-leaf manuscript was the most fascinating exhibit I saw in a museum. It was carefully preserved and displayed in a glass case. The script, written with natural ink, revealed centuries-old wisdom and historical records. This artefact highlighted the challenges and craftsmanship of early documentation. The preservation techniques used ensured the delicate leaves remained intact. Observing such an exhibit made me appreciate how knowledge was recorded and passed down before the invention of paper and printing.
