समुंदर में तैरना नदी के मुक़ाबले आसान क्यों होता है?

कदोस्तोँ क्या कभी आपने सोचा है की नदी में तैरना इतना मुश्किल क्यों और समुंदर में तैरना आसान क्यों होता है? इसके पीछे भी साइंस है आर्कमिडीज प्रिंसिपल कहता है की कोई भी ऑब्जेक्ट पानी की सतह पर तभी तैरेगा जब उसके द्वारा पानी में की गयी डिस्प्लेसमेंट उसके वज़न के बराबर होगी।

दोस्तों जब हम समुंदर के पानी पर तैर रहे होते हैं तो हमारे द्वारा हटाए गए पानी का वज़न ज्यादा होता है जबकि नदी में तैरने पर हटाए गए पानी का वज़न कम होता है इसका कारण है समुंद्री पानी का नमकीन होना। नदी की अपेक्षा समुंदर के पानी का घनत्व ज्यादा होता है। ज्यादा डेंसिटी होने के कारण समुंदर के पानी में बोयनकी फाॅर्स ज्यादा लगती है जिससे हम समुंदर पर आसानी से तैर सकते हैं। है न कमाल!!

However, there are significant advantages to using a bonus code. It often opens up a lot of other rewards and bonuses for new players. It also stops existing players from exploiting bonuses and makes the playing ground much fairer.
