1 मीटर लम्बा 1 मीटर चौड़ा और 1 मीटर ऊंचा पानी का ब्लॉक 1000 kg वहीं सोने का ब्लॉक 19320kg तांबे का 8930kg लोहे का 7850kg रहेगा। आकार वही किन्तु भार में अंतर द्रव्यमान है। यही स्पेसिफिक ग्रेविटी है। शायद में समझ गया हूँ😍😍

If a diamond rough has shells and skins then obviously even if it is diamond it will show different specific gravity . Specific gravity test cannot be done on roughs but only on polished gem stones. Moreover specific gravity should be done with distilled water bottle RO water because it contains dissolved minerals.

नकली सोना बनाने के लिए तांबे में वजन के अनुपात में 10% एल्युमिनियम मिलाया जाता है। इसे असली नकली सोने में फर्क नहीं किया जा सकता। किन्तु नकली सोने का वजन असली की अपेक्षा आधे से थोड़ा कम होता है। सिंपल😀

No sir you are wrong. Two objects will touch ground simultaneously. Velocity of free falling object doesn't depend on the mass of the object, it depends on acceleration and here acceleration due to gravity is constant.
