السلام عليكم ورحمة الله وبركاته Question 1 Part a) density = mass/volume , ρ = m / V Mass is given , Volume of sphere is = (4/3)*pi*r^3 Part b) Specific gravity = density of fluid or substance / density of water , SG = = ρ / ρH2O density of fluid or substance we have found it in part a density of water we knew it as 1000 kg/m^3 يرجى التأكد من الإجابات .. وإن شاء الله تكون صحيحه ووفقك الله |
