आयशा ने रेसिंग प्रतियोगिता के लिए एक ड्रोन बनाया, जो 20 मीटर की ऊँचाई पर उड़ता है। पिछले साल के विजेता ड्रोन की गति 40 किमी/घंटा थी, लेकिन आयशा के ड्रोन में गति मापने का यंत्र या जीपीएस नहीं था। उसके दोस्त विवेक ने उड़ते हुए ड्रोन की कुछ तस्वीरें ली थीं। तस्वीरों में टाइमस्टैम्प देखकर, आयशा ने अपने और ड्रोन के बीच के कोण (30° और 60°) मापे, जिनके बीच 1.53 सेकंड का अंतर था। त्रिकोणमिति का उपयोग करके, उसने ड्रोन की गति 54 किमी/घंटा निकाली, जो 40 किमी/घंटा से अधिक है। अब इस साल जीत पक्की है!
Ayesha built a drone for a racing competition that flies at a height of 20 meters. Last year’s winning drone had a speed of 40 km/h, but Ayesha’s drone lacked a speedometer or GPS to measure its speed. Her friend Vivek suggested using photos he had taken of the drone in flight. Noticing the timestamps, Ayesha measured the angles between her and the drone in two photos (30° and 60°) with a time gap of 1.53 seconds. Using trigonometry, she calculated the drone’s speed to be 54 km/h—well above 40 km/h. This year, victory seems certain!
Ayesha ne racing competition ke liye ek drone banaya.
Joki 20 m ki height pe udta hai. Par pichle saal competition jeetne wale drone ki speed 40 kilometer prati ghanta thi. Kya ye drone 40 ki speed se udd sakta hai? Chalo dekhte hain kaise Ayesha ne apne drone ki speed naapi, aur kya wo iss saal race jeet payegi?

About TicTacLearn -
We firmly believe that education is the greatest equalizer of all! But unfortunately, we live in a world where access to quality learning resources is limited and comes with an associated price-tag, effectively perpetuating inequity in the society.
We have set out to change that.
At TICTACLEARN we believe that digital content has the power to reshape the learning spaces in the country and we want to take it one step closer to every learner, educator and parent. With that in mind we have created one of the largest open-source repositories of high-quality, curriculum aligned digital learning resources (~12,000 videos, aligned item bank, etc.) available for everyone, free of cost! Furthermore, we know that educational resources are most effective when in the learners native language, and hence we aim to make our videos available in all major Indian languages.
